1 SCOPE OF THE EAD


1.1 Description of the construction product
1.1.1 Common

External Thermal Insulation Composite System (ETICS) with rendering, on insulation boards based on
expanded polystyrene and cement, is intended for use as external thermal insulation to the walls of
buildings. The kit is based on thermal insulation made of boards based on expanded polystyrene and
cement, covered by EAD 040065-00-1201. The thermal insulation boards are factory made products of
homogenous mixture of the granulates of expanded polystyrene and Portland cement Cem I 42,5 according
to EN 197-1 1, not containing any other natural or artificial aggregate. The walls for installation of the product
are made of masonry (bricks, blocks, stones ...) or concrete (cast on site or as prefabricated panels).

The ETICS kit 2 comprises a prefabricated thermal insulation product installed onto the wall by bonding
with supplementary mechanical fixings (anchors) or by mechanical fixing (anchors) with supplementary
bonding. Types of installation are detailed in 1.3.2. The thermal insulation product is faced with a rendering
consisting of one or more layers applied in-situ, one of which contains reinforcement. The rendering is
applied directly to the insulating panels, without any air gap or disconnecting layer.

This EAD applies only to ETICS kit based on following specifications:

- specific thermal insulation product, based on expanded polystyrene and cement boards
according to EAD 040065-00-1201, with short-term water absorption higher than 1 kg/m2
after 24 hours of partial immersion and with accuracy of width ± 3 mm as maximum, and
base coat specified by manufacturer
- rendering system with the water absorption after 1 hour less than 1 kg/m2, if the water
absorption of the reinforced base coat itself after 1 hour is equal to or more than 1 kg/m2,
- base coat reinforced by glass fibre mesh,
- render coating created by any combination of key coat, finishing coat and/or decorative
coat; eventually created by thin facing elements based on aqueous dispersion of
macromolecular binders and bonded to the base coat by dispersion adhesive,
- kit fixed to the substrate by means of one of the following methods:
o by bonding with supplementary mechanical fixings (see 1.1.2.1.2) with 20 %
bonded surface area as minimum,
o by mechanical fixing with supplementary adhesive (see 1.1.2.2.1),
- kit, where following features comply with provisions of:
o 2.2.9.2 for bond strength between adhesive and thermal insulation product
o 2.2.9.3 for bond strength between thermal insulation product and base coat
o 2.2.11 for shear strength and shear modulus of elasticity of thermal insulation
product.
- plastic anchors for ETICS according to EAD 330196-01-0604.
- biocide preparations only, used for treatment of render coat, approved according to
Regulation (EU) No 528/2012.
This EAD does not apply to ETICS kit based on any of following components and/or conditions: 3

1 All undated references to standards or to EADs in this EAD are to be understood as references to the dated
versions listed in Chapter 4.
2 See 1.3.2.
3 ETICS kits based on any construction parameter(s) mentioned below may lead to serious imperfections of
installed ETICS and therefore they may require for their proper function as product additional testing not included
in the scope of this EAD.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 6/97

- other types of facings such as brick slips and/or ceramic tiles or artificial and/or natural
stone boards etc.,
- special plastic anchors with plate where connection between anchor plate and thermal
insulation product is provided only by layer of adhesive,
- ETICS applied down to the ground on foot of buildings and exposed to rising damp.

The insulation layer can consist of two insulation boards, bonded together by an adhesive, specified by the
manufacturer. The ETICS with such an insulation layer shall be assessed only as a mechanically fixed one
with a supplementary bonding (see 1.1.2.2.1). Installation of kit goes beyond the EAD.

The ETICS can optionally include special fittings (e.g. base profiles, corner profiles ...) for its connection to
adjacent building structures (apertures, corners, parapets ...). These optional accessories are to be
specified by manufacturer either by specific type or by intended performances and implemented by him into
the ETICS kit specification. These optional accessories can have a significant impact on the durability of
system installed.

The product is not covered by a harmonised European standard. The product is not fully covered by EAD
040083-00-0404, which doesn’t cover:

- ETICS based on insulation product with water absorption higher, than specified as limit
of scope of EAD 040083-00-0404,
- ETICS based on thermal insulation product with coefficient of thermal conductivity
exceeding 0,065 W/(m.K), specified as limit of scope of EAD 040083-00-0404
- façade fire performance,
- mass activity of natural radionuclides,
- content, emission and/or release of dangerous substances,
- test of hygrothermal behaviour according to EN 16383.

It is assumed that the product will be installed according to the manufacturer’s instructions and/or in
absence of such instructions according to the usual good practice of the building professionals. Original
expansion joints in substrate walls shall be abiding in the entire composition of ETICS installed.

Relevant manufacturer’s stipulations having influence on the performances of the product covered by this
European Assessment Document shall be considered for the determination of the performance and detailed
in the ETA.

1.1.2 Types of ETICS

From the design point of view and content of this EAD, ETICS are differentiated according to the
methods of fixing to transfer embedded load into substrate:

1.1.2.1 Bonded ETICS

ETICS where the connection to the substrate is ensured by bonding. If specified, optionally they can
include supplementary mechanical fixings.
The load is distributed only by the bonding layer. Requirements on fire safety for position, shape and
dimensions of strips and/or dabs are to be taken into account.

1.1.2.1.1 Purely bonded ETICS

ETICS where no mechanical fixing is used. Purely bonded ETICS may be fully bonded (over the
entire surface) or partially bonded in strips and/or dabs. No mechanical fixing is used.
Note: This type of ETICS is stated in this specification only for complete information and it is not
covered by this EAD.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 7/97

1.1.2.1.2 Bonded ETICS with supplementary mechanical fixings

ETICS where the mechanical fixing is used primarily to provide stability and flatness of outer face
insulation boards and acts as a connection to avoid the risk of detachment. Mechanical fixing can
also provide stability in case of fire.
The load is distributed only by the bonding layer. Requirements on fire safety for position, shape and
dimensions of strips and/or dabs are to be taken into account.

1.1.2.2 Mechanically fixed ETICS

ETICS where the connection to the substrate is ensured by mechanical fixing. If specified, it can
optionally include supplementary bonding.
The load is distributed primarily by the mechanical fixing. Requirements on fire safety on position,
shape and dimensions of strips and/or dabs in case of mechanically fixed ETICS with supplementary
adhesive are to be taken into account.

1.1.2.2.1 Mechanically fixed ETICS with supplementary adhesive

ETICS where the load is distributed to substrate primarily by the mechanical fixing. The adhesive is
used primarily to ensure the flatness of the installed ETICS and, if specified, to distribute the self-
weight of system into substrate. Requirements on fire safety on position, shape and dimensions of
strips and/or dabs in case of mechanically fixed ETICS with supplementary adhesive are to be taken
into account.

1.1.2.2.2 Purely mechanically fixed ETICS

ETICS where the complete load is distributed to the substrate by mechanical fixing only. It is secured
on the wall only by mechanical fixing at all-times. The ETICS with the bonded area less than 20 % is
considered to be purely mechanically fixed too.
Note: This type of ETICS is stated in this specification only for complete information and it is not
covered by this EAD.

1.2 Information on the intended use(s) of the construction product


1.2.1 Intended use(s)

The product is intended for use as external thermal insulation to the external walls of buildings. The
ETICS can be used on new or existing (retrofit) vertical walls. It can be used on adjacent horizontal or
inclined surfaces of façades (e.g. bow windows), which are not exposed to precipitation, too. Types of
substrate walls, this EAD refers to, are specified in 1.1.1.
The ETICS is designed to give the wall, to which it is applied, satisfactory thermal insulation. It should
provide a minimal thermal resistance in excess of 1 m2.K/W. In specific use, smaller thicknesses of
insulation can be used subject to checking, that there is no particular problem.
The ETICS is non load-bearing construction element. It does not contribute directly to the stability of the
wall on which it is installed. The ETICS can contribute to durability by providing enhanced protection
from the effects of weathering.
The ETICS as the product is not intended to ensure the airtightness of the building structure. Types of
ETICS covered by this EAD are specified in 1.1.1.
ETICS is expected to be designed and installed on action of dead mass, wind action and/or on action
of thermal expansion in accordance with provisions of EN 1990, EN 1991-1-1, EN 1991-1-4 and EN
1991-1-5. The assessment methods given in the 2.2 are based on general experience with behaviour
of ETICS in different climatic conditions of the Europe.
Surface temperatures of the order from -20 °C up to +80 °C are generally regarded as the extremes in
temperature change. However, the temperatures of the air can sometimes in Northern Europe decrease to
-40 °C, according to common experience test temperature -20 C is generally considered to be sufficient
for testing of freeze/thaw resistance. Solar radiation, depending on radiation flow and absorbability of the

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 8/97

surface (esp. its colour) can increase the surface temperature up to +80 °C. More details are stated in EN
1991-1-5.

1.2.2 Working life/Durability

The assessment methods included or referred to in this EAD have been written based on the request to
take into account a working life of the ETICS for the intended use of 25 years when installed in the works.
These provisions are based upon the current state of the art and the available knowledge and experience.
When assessing the product, the intended use as foreseen by the manufacturer is to be taken into account.
The real working life may be, in normal use conditions, considerably longer without major degradation
affecting the basic requirements for works. 4
The indications given as to the working life of the construction product cannot be interpreted as a guarantee
neither given by the product manufacturer or his representative nor by EOTA when drafting this EAD nor
by the Technical Assessment Body issuing an ETA based on this EAD, but are regarded only as a means
for expressing the expected economically reasonable working life of the product. 5

4 The real working life of a product incorporated in a specific works depends on the environmental conditions to
which that works is subject, as well as on the particular conditions of the design, execution, use and maintenance
of that works.
5 Therefore it cannot be excluded that in certain cases the real working life of the product may also be shorter than
referred to above.

European Assessment Document – EAD 040759-00-0404 9/97

1.3.3 Composition of ETICS components

Composition of ETICS components as the adhesive, the base coat and the finishing coat can include
a range of binders from pure polymeric to pure cementitious. They are available in the following
forms:

- Powder (dry mortar) blended at the factory that requires only mixing with a quantity of water
specified by the manufacturer;

- Powder requiring addition of extra binder;

- Paste requiring addition of cement;

- Ready to use paste, supplied in workable consistency;

1.3.4 Adhesive

ETICS component used for bonding of the thermal insulation product to the wall substrate.

1.3.5 Thermal insulation product

Factory made boards based on expanded polystyrene and cement according to EAD 040065-00-
1201, prepared by casting of fresh mass into moulds. The insulation layer may consist of two
insulation boards bonded together by an adhesive defined by the manufacturer of thermal insulation
product. In this case, the ETICS shall be executed as mechanically fixed only.

For purpose of specification of ETICS according to this EAD the thermal insulation product is
determined at least by its material base, macrostructure of cross section of boards, tensile strength
perpendicular to faces without significant variability in wet conditions, class of reaction to fire and
its coefficient of thermal conductivity (D value).

Lambda declared D declared at 23 ºC and 50 % relative humidity is to be applied for evaluation


according to this EAD.

1.3.6 Rendering system

All the coats applied to the outer face of the thermal insulation product together with the
reinforcement. Rendering system consists of one or more site applied layers, one of which contains
reinforcement (see 1.1.1.).

- Base coat:

Coat applied directly onto the thermal insulation product; the reinforcement is embedded into it
and provides most of the mechanical properties of the rendering,

- Reinforcement:

Glass fibre mesh embedded in the base coat to improve its mechanical strength. Differentiation
is made between:

- Standard mesh: embedded in the base coat all over the area and tied positively at joints,
mostly by overlapping,

- Reinforced mesh: optionally embedded in the base coat to the standard mesh to improve
the impact resistance, generally applied without overlapping.

- Render coating:

The render coating is applied to the base coat in one or several layers by application of a new
layer on top of a last existing hardened layer. Installation also can be done in several layers
(putting one layer on top of a fresh layer).

Generally, multi-layer renders include the following:

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 10/97

- Key coat: Very thin coat which may be applied to the base coat and is intended to act as
a preparation for the application of the finishing coat. It can also be possibly used for
aesthetic reasons (for example in case of “dark” ribbed finishing coats),

- Finishing coat: Coat which contributes to the protection against weathering and can
provide a decorative finish; it is applied onto the base coat with or without a key coat. If
two finishing coats differ only in size of aggregate, they are considered as one type,
concerning their composition EN 15824 and/or EN 998-1 apply

- Decorative coat: Coat which generally contributes to the aesthetic finishing (to cover
efflorescence ...) of the finishing coat and can also provide supplementary protection
against weathering.

Render coating eventually can be replaced by thin facing elements based on aqueous dispersion
of macromolecular binders and bonded to the base coat by dispersion adhesive.

In specific case base coat can work as finishing coat as well and no more layers are applied on its
surface. In this case the application of a finishing coat prescribed in relevant test procedures shall
be omitted.

1.3.7 Mechanical fixing - plastic anchors for ETICS

Plastic anchors for ETICS according to EAD 330196-01-0604 used to fix the ETICS on the substrate
against effects of wind action (if specified), against thermal actions (if specified and/or if necessary)
and/or to provide stability of outer surface of thermal insulation boards.

1.3.8 Ancillary components

Any supplementary component or product specified by manufacturer as the option part of the
ETICS kit and used in the ETICS, e.g. to form joints (mastics, corner strips, etc...) or to achieve
continuity (mastic, joint-covers ...).

1.3.9 Substrate

The term “substrate” refers to a wall, which in itself already meets the necessary airtightness and
mechanical strength requirements (resistance to static and dynamic loads).

It may be raw (without any covering) or faced with mineral or organic renders or paints or with tiles.

- Masonry walls:

Walls constructed from units of burnt clay, concrete, calcium silicate, autoclaved aerated concrete
or stone laid using mortar and/or adhesive.

- Concrete walls:

Walls made of concrete either cast in situ or prefabricated at the factory.

1.3.10 Rpanel

of thermal insulation product tested, expressed in N.

1.3.11 Rjoint

The mean or single failure load in pull-through test with single anchor placed at “T” panel joints
between bodies of thermal insulation product tested, expressed in N.

1.3.12 Rk

expressed in kN/m2.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 11/97

1.3.13 Design value of wind load resistance Rd

Design value of wind load resistance Rd is to be determined according to equation:

where:
- Rd design value of wind load action
- M partial safety coefficient, representing all potential negative effects of
manufacturing, storage, installation and use of product, usually given in national
regulations for design of ETICS. If no national regulations are given, value of 2.0
can be applied. Values of partial safety coefficient can differ for evaluated sections
of kit.
- Rk characteristic value of wind load action (see 1.3.12), determined by tests or as
lower value determined by calculation according to equations:
Rk = (Rpanel × npanel + Rjoint × njoint) × kk
and
Rk = NRk × (npanel + njoint)
where:
- Rpanel the mean failure load in pull-through test with single anchor placed at the middle
of body of insulation panel (see 1.3.10),
- Rjoint the mean failure load in pull-through test with single anchor placed at “T” panel
joint of insulation panels (see 1.3.11)
- NRk characteristic value of pull-off resistance of plastic anchor for ETICS given in its
technical specification
- npanel number of plastic anchors for ETICS placed at the middle of body of insulation
panel
- njoint number of plastic anchors for ETICS placed at “T” panel joint of insulation panels
- kk reduction factor for calculation of characteristic value from mean values of Rpanel,
Rjoint, given in national regulations for design of ETICS,

1.3.14 Minimal bonded surface area S for bonded ETICS

The minimal bonded surface area S for bonded ETICS is calculated as follows:

30
S=  100 in %
B

where:

- S minimal bonded surface area, expressed in %

- B minimum single failure resistance of the adhesive to the thermal insulation product
in dry conditions for all failure modes, expressed in kPa

- 30 bond strength between adhesive and thermal insulation product in kPa


corresponding to minimal requirement on bonded ETICS (see 1.1.2.1).

Taking this formula into account, the minimum bond strength lower than 30 kPa would lead to a bonded
surface higher than 100 %. Such the ETICS is to be consequently mechanically fixed.

1.3.15 Length of the wall or the distance between expansion joints

The length of the wall or the distance between expansion joints L [m] is calculated using the following
equation as a function of the relevant T:

T temperature variations in the reinforced base coat of rendering according to EN 1991-1-5 and
its national annexes,

L length of wall or distance between expansion joints expressed in m.

1.3.16 Countersunk assembly

flat hole of specified depth in external surface of thermal insulation product or screwed into specified
position in thickness of thermal insulation product. Position of anchor plate in thickness of thermal insulation
product specifies manufacturer of ETICS in his manual.

Countersunk assembly significantly effects achieved test level of resistance of mechanical fixing in relation
of position of anchor plate to back surface of board of thermal insulation product and its macrostructure
(see 1.3.5).

1.3.17 Surface assembly

Surface assembly is the opposite type of countersunk assembly, when complete plate of anchor, or its
substantial part, consisting of external circle in case of spatially shaped plate, leans on external surface of
thermal insulation product.

2.2 Methods and criteria for assessing the performance of the product in relation
to essential characteristics of the product
This chapter is intended to provide instructions for TABs. Therefore, the use of wordings such as “shall be
stated in the ETA” or “it has to be given in the ETA” shall be understood only as such instructions for TABs
on how results of assessments shall be presented in the ETA. Such wordings do not impose any obligations
for the manufacturer, and the TAB shall not carry out the assessment of the performance in relation to a
given essential characteristic when the manufacturer does not wish to declare this performance in the
Declaration of Performance.

If for any components covered by harmonised standards or European Technical Assessments the
manufacturer of the component has included the performance regarding the relevant essential
characteristic in the Declaration of Performance, retesting of that component for issuing the ETA under the
current EAD is not required.

2.2.1 Reaction to fire

The external thermal insulation composite systems (ETICS) with rendering on boards based on polystyrene
and cement shall be tested using the test method(s) for the corresponding reaction to fire class according
to EN 13501-1 in order to be classified according to the Commission Delegated Regulation (EU) No
2016/364.

The determination of the critical case(s) as well as the mounting and fixing provisions that are considered
to be appropriate for the testing and are representative of the intended end use application are specified in
Annex A. The mounting and fixing conditions for the tests are specified in Annex A.

The class of reaction to fire of the kit is given in the ETA.

The reaction to fire of thermal insulation product is given in the ETA, preferably according to CE marking of
product, given by its manufacturer. If its class of reaction to fire is not available and when the product
destination is a MS with this specific regulatory requirement, it is to be tested using the test method(s)
relevant for the corresponding class of reaction to fire according to the Commission Delegated Regulation
(EU) No 2016/364.

2.2.2 Facade fire performance

If the manufacturer intends to declare the façade fire performance of the product, in absence of a European
assessment approach, the ETA shall be issued taking into account the situation in the Member States
where the manufacturer intends his product to be made available on the market.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 16/97

Information about such situation is included in Annex A.6.

The test result(s) according to relevant test method(s), selected by manufacturer from content of Annex
A.6, expressed as level and/or description, is(are) given in the ETA.

2.2.3 Water absorption

Water absorption of reinforced base coat itself and of complete rendering system(s) of ETICS, applied on
thermal insulation product, is to be tested according to Annex B.

This characteristic of base coat depends on action and penetration of fresh base coat into surface of thermal
insulation product. The characteristic of complete rendering system depends on its ingredients (key coat,
finishing coat, decorative coat) and their material composition (particle size grading, type and content of
binder and additives and admixtures). Achieved level of both characteristics can vary with change of any
detail in composition.

If the average value of the water absorption of the reinforced base coat after 1 hour is more than 1 kg/m2
the average value of the water absorption after 1 hour of the ETICS with each complete rendering system
shall be less than 1 kg/m2 otherwise the ETICS with the corresponding rendering is not acceptable – see
the synopsis given on the Figure 1 6.

Following characteristics are given in the ETA:


- the average value of the water absorption in kg/(m2.h) of the reinforced base coat after 1 hour and
after 24 hours,
- the average value of the water absorption after 1 hour and after 24 hours of each complete rendering
system (i.e. reinforced base coat covered with each type of finishing coat and /associating or not/
key coat and/or decorative coat).
Besides, the short-term water absorption of the thermal insulation product, determined according to Clause
2.2.3.1 of EAD 040065-00-1201, should be given in the technical description of the ETICS.

2.2.4 Water vapour permeability

The water vapour permeability is expressed as water-vapour diffusion-equivalent air layer thickness
according to EN ISO 12572.

The characteristic depends directly on content and type of binder, particle size grading of used aggregate
and filler and content of other components (e.g. additives, admixtures or pigment) and varies with their
changes.

Water vapour permeability of the system and of its parts and related characteristics are to be tested for the
critical case according to 2.2.4.1 and 2.2.4.2.

Following characteristics are given in the ETA:


- the average value of water-vapour diffusion-equivalent air layer thickness in meters (of air) of each
rendering system(s) according to 2.2.4.1,
- the two-sided confidence interval of water-vapour resistance factor  at the confidence level 95% of
thermal insulation product according to Clause 2.2.2 of EAD 040065-00-1201.
- particle size grading of base coat material and finishing coat (if relevant) used for tests according to
L.11.4 of Annex L,
- ash content of base coat, finishing coat, key coat and/or decorative coat used for tests according to
L.1.1.3 of AnnexL,

- average value of density of hardened base coat used for tests according to L.1.3 of Annex L.

European Assessment Document – EAD 040759-00-0404 17/97

2.2.4.1 Water-vapour diffusion-equivalent air layer thickness of system

The test is to be performed on all the configurations of rendering systems proposed by the manufacturer,
i.e. reinforced base coat covered with each type of finishing coat and (associating or not) key coat and/or
decorative coat. If the application of the key coat and/or the decorative coat is optional, configurations with
and without have to be tested.

The test of water vapour permeability of system is to be performed at least on five test samples for each
configuration according to Annex C.

2.2.4.2 Characteristics of rendering

Particle size grading of base coat material and finishing coat is to be tested according to L.1.1.4 of Annex
L, using test method appropriate to material tested (paste or powder).

Ash content of base coat, finishing coat, key coat and/or decorative coat are to be tested according to
L.1.1.3 of Annex L,

Density of hardened base coat is to be tested according to L.1.3 of Annex L, on samples for tests according
to L.1.3.1 and/or L.1.3.2 of Annex L. Average value of density shall be calculated with accuracy in 10 kg.

2.2.5 Watertightness

Based on evaluation of water absorption according to 2.2.3 and Annex B, watertightness of ETICS is to be
determined by the hygrothermal test on the rig, the test of freeze-thaw resistance according to synopsis
given on the Figure 1, the test of water retention capability of fresh mortar of base coat according to L.1.2.1
of Annex L, and the test of freeze-thaw resistance with the complete system exposed to water.

The characteristic depends directly on tensile strength and thickness of used base coat, its capability to be
applied in vertical position expressed by water retention capability of fresh mortar, particle size grading and
type of binder and additives/admixtures in used finishing coat, application or not of key coat and/or
decorative coat, on tensile strength of used glass fibre reinforcement and its position in layer of base coat
and on execution of connections between strips of reinforcement. The characteristic can vary significantly
with any change of mentioned components.

The characteristic can vary in dependence on number and type of applied climatic cycles too.

Following characteristics are given in the ETA:


- the selected type of test of hygrothermal behaviour, description of condition of surface of test rig after
finish of hygrothermal behaviour test, eventual presence of surface damage and its type and size
according to 2.2.5.1

rendering system according to 2.2.5.2, if applicable
- assessment of freeze-thaw resistance of the complete system determined by tests and description
of samples after test according to 2.2.5.4, if applicable
- the average value, the minimum value and the estimation of standard deviation of bond strength
after freeze-thaw test according to 2.2.5.2 and 2.2.5.4 if applicable,

European Assessment Document – EAD 040759-00-0404 19/97

2.2.5.1 Hygrothermal behaviour

The hygrothermal behaviour of the product is to be assessed by hygrothermal test on the rig. Manufacturer
can select type of test according to his intent and/or national rules for application of the product in the
Member States, as follows:

- Test according to Annex I (test equivalent to Clause 2.2.6 of EAD 040083-00-0404), consisting from:
a) 80 cycles of heating to (70 ± 5) C and spraying by water (15 ± 5) C
b) 5 cycles of heating to (50 ± 5) C and cooling to (-20 ± 5) °C

- Test according to EN 16383 with area of the test rig minimally 6 m2, consisting from:
a) 80 cycles of heating to (70 ± 5) C and spraying by water (15 ± 5) C
b) 5 cycles of heating to (50 ± 5) C and cooling to (-20 ± 5) °C
c) 30 cycles of wetting by water (15 ± 5) C, freezing to (-20 ± 5) °C and thawing by spraying water
(15 ± 5) C.

Details of test (e.g. air humidity, time of test segments, water flow for sprinkling etc.) are given in relevant
test document.

If manufacturer doesn’t specify type of the test, the test according to EN 16383 with area of the test rig
minimally 6 m2 is to be performed.

The critical configuration of the specimen shall be selected in both cases according to the following rules:

- At least the worst case (e.g. maximum water absorption of the ETICS components, minimum cohesion
and adherence of ETICS components, minimum thickness of ETICS components, minimum bonded
surface area, minimum density of fixings, etc.) or the more representative case of the ETICS shall be
tested.

- Generally, only one reinforced base coat shall be used for the whole specimen.

- At the very most two exterior skins (different nature of finishing coats) can be applied per opening in
the test wall (vertical divisions). Maximum two configurations in the case one opening and maximum
four configurations in the case of two openings.

- If several ETICS differ only in the type of insulation board, two insulation boards can be applied to the
test wall (one per opening). If two different insulation boards are tested, they shall have the same
thickness.

- If different exterior skins are used, the lower part of the test wall (A = 1/3 of the total height) consists of
the reinforced base coat alone (without any skin).

If base coat of product has specified thickness up to 5 mm, in both cases at least 5 test specimens for test
of static modulus of elasticity, tensile strength and elongation at break according to 2.2.16.3.3 are to be
prepared together with installation of the product on the rig, inserted into window on the rig before the
intrinsic test and exposed during the whole test.

Test of water retention capability of fresh mortar of base coat, used for preparation of the test rig, is to be
performed according to 2.2.5.3.

After finishing the test of the hygrothermal behaviour and conditioning of the test rig at minimum for 7 days
at ambient temperature (20 ± 10) °C, in both cases the tests of resistance to impact according to Annex E,
the tensile bond strength of reinforced base coat to the thermal insulation product to F.4 of Annex F, and
the tensile bond strength of the finishing layer to the base coat according to F.5 of Annex F, are to be
performed.

The test in both cases is evaluated as satisfactory if following defects either on the reinforced base coat (if
a part without finishing coat is required) or on the ETICS itself have occurred neither during nor at the end
of each part of test:

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 20/97

- blistering or peeling of any finishing coat,


- failure or cracking associated with joints between thermal insulation product boards or profiles fitted
with ETICS,
- detachment of the render coat,
- cracking allowing water penetration to the insulating layer (normally ≤ 0.2 mm).

2.2.5.2 Freeze-thaw resistance

Freeze-thaw resistance of the ETICS is considered as to be satisfactory if the water absorption according
to 2.2.3 of both the reinforced base coat and the rendering system is less than 0.5 kg/m² after 24 hours.

In all other cases the test of freeze-thaw resistance according to Annex D is to be performed. Synopsis for
tests of watertightness and freeze-thaw resistance is given on the Figure 1.

The freeze-thaw resistance of the ETICS is evaluated as to be satisfactory if:


- samples after test show none of the defects described in 2.2.5.1 and
- bond resistances in failure after cycles satisfy the requirements of 2.2.9.3. and/or 2.2.16.1.

2.2.5.3 Water retention capability of fresh mortar of base coat

The water retention capability of fresh mortar prepared for base coat is to be tested on one specimen
according to L.1.2.1 of Annex L.

2.2.5.4 Freeze-thaw resistance of the complete system exposed to water

The freeze-thaw test with the complete system exposed to water, if the water absorption of the thermal
insulation is higher than 1 kg/m2 is to be performed according Annex D.

Freeze-thaw behaviour of the ETICS shall be assessed by means of bond strength tests (see 2.2.16.1) of
specimens taken from the ETICS submitted to the freeze-thaw cycles indicated in D.5 of Annex D.

At least the worst case (e.g. maximum water absorption of the ETICS components, minimum cohesion and
adherence of ETICS components, maximum thickness of ETICS components, etc.) or the more
representative case of the ETICS shall be tested.

If any of the following defects occur during or at the end of the freeze-thaw cycles programme, it shall be
recorded:
- deterioration such as cracking that allows water penetration to the internal layers;
- detachment of the skin;
- irreversible deformation.

2.2.6 Mass activity of natural radionuclides

Mass activity of natural radionuclides Radium Ra-226, Thorium Th-232 and Potassium K-40 and activity
concentration index I are to be determined for ETICS based on component(s) from any of building materials
specified in positive list given in Directive 2013/59/EURATOM, Annex VIII on one test specimen for each
relevant component of ETICS.

Mass activity of natural radionuclides Radium Ra-226, Thorium Th-232 and Potassium K-40 is to be
determined by test according to EN ISO 10703 with modifications in Clause 10.1 (Preparation of sample)
and Clause 11.1, Equation 4 (Calculation of volume activity) given below.

Materials in powder or paste form are to be used for test directly, hardened materials are to be crushed to
particle size grading 0/2 mm. Test specimen is to be prepared by filling of tested material with natural
humidity of volume of the amount 0,45 to 0,50 litre into Marinelli’s container. Net weight m [kg] of test
specimen is to be determined with accuracy in grams.

Than mass activity of radionuclides Radium Ra-226, Thorium Th-232 and Potassium K-40 is to be
measured according to Clause 10.1.1 of EN ISO 10703, Test is to be evaluated according to Clause 11 of
EN ISO 10703, in calculation relations instead of volume of tested specimen V the measured net weight of
tested specimen m in [kg] is to be used.

The activity concentration index I [-] is to be calculated from determined values of mass activity of Radium
Ra-226, Thorium Th-232 and Potassium K-40 by the formula given in Directive 2013/59/EURATOM, Annex
VIII.

Following characteristics for relevant component(s) are given in the ETA:


- the mass activity of the radionuclides Ra-226, Th-232 and K-40 in Bq/kg;
- the calculated value of activity concentration index I [-].

2.2.7 Content, emission and/or release of dangerous substances

The performance of the product related to the emissions and/or release and, where appropriate, the content
of dangerous substances will be assessed on the basis of the information provided by the manufacturer 7 after
identifying the release scenarios (in accordance with EOTA GD 014) taking into account the intended use
of the product and the Member States where the manufacturer intends his product to be made available on
the market. Purely inorganic materials (e.g. boards, adhesives) do not have to be tested.

The identified intended release scenarios for this product and intended use with respect to dangerous
substances are:
IA2: Product with indirect contact to indoor air (e.g. covered products) but possible impact on indoor
air
S/W1: Product with direct contact to soil, ground- and surface water
S/W2: Product with indirect contact to soil, ground- and surface water.

2.2.7.1 SVOC and VOC

For the intended uses covered by the release scenarios IA2, semi-volatile organic compounds (SVOC) and
volatile organic compounds (VOC) shall be determined in accordance with EN 16516. The loading factor
to be used for emission testing is 0,007 m2/m3.

The preparation of the test specimen is to be performed as follows: The inert substrate (sandblasted glass
or stainless steel) shall be coated by tested material as described in the manufacturer's instructions. Testing
is performed using ¾ of the maximum wet film thickness according to the manufacturer's instructions. For
each layer the quantity applied is verified in terms of wet weight [g/m²] by taking weight differences.

The coating shall be carried out exactly in accordance with the manufacturer's specifications. Environmental
conditions and drying time have to be reported. Cross contaminations shall be avoided.

Once the test specimen has been completely coated, it is preconditioned for 3 or 28 days. The
preconditioning process takes place in a test chamber under the test chamber conditions or in a storage
facility where the relevant test chamber conditions can be created.

7 The manufacturer may be asked to provide to the TAB the REACH related information which he must accompany the DoP with
(cf. Article 6(5) of Regulation (EU) No 305/2011). The manufacturer is not obliged:
− to provide the chemical constitution and composition of the product (or of constituents of the product) to the TAB, or
− to provide a written declaration to the TAB stating whether the product (or constituents of the product) contain(s) substances
which are classified as dangerous according to Directive 67/548/EEC and Regulation (EC) No 1272/2008 and listed in the
"Indicative list on dangerous substances" of the SGDS.
Any information provided by the manufacturer regarding the chemical composition of the products may not be distributed to
EOTA or to TABs.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 22/97

Once the preconditioning time has been observed, the test specimen is transferred to the emission test
chamber. This point in time is considered to be the starting time of the emission test. A 28-day test period
using the area-specific air flow rate q = 1,5 m/h takes place.

The test results have to be reported for the relevant parameters (e.g. chamber size, temperature and
relative humidity, air exchange rate, loading factor, size of test specimen, preconditioning, production date,
arrival date, test period, test result).

The relevant test results after 28 days shall be expressed in [mg/m³] and given in the ETA.

2.2.7.2 Leachable substances


For the intended use covered by the release scenario S/W1 or S/W2 the performance of the rendering
system applied on inert substrate (sandblasted glass or stainless steel) (hereafter “sub-kit”) concerning
leachable substances is to be assessed. A leaching test with subsequent eluate analysis must take place,
each in duplicate. Leaching tests of the test specimens are conducted according to CEN/TS 16637-2:2014.
The leachant shall be pH-neutral demineralised water and the ratio of liquid volume to surface area shall
be (80 ± 10) l/m².

The sub-kit to be tested shall be assembled according to manufacturer’s instructions. Preparation is


performed using ¾ of the maximum wet film thickness for each layer. The quantity applied in each layer is
verified in terms of wet weight [g/m²] by taking weight differences.

Notes: 1) Superficial damage, provided there is no cracking, is considered as showing “no deterioration” for all the
impacts
2) The test result is assessed as being “penetrated” if circular cracking penetrating as far as the thermal
insulation product is observed for at least 3 of the 5 impacts.

2.2.9 Resistance to embedded loads - bond resistance

Evaluation of resistance to embedded loads for bond resistance and resistance of mechanical fixing (see
2.2.10) is to be performed according to type of ETICS (see 1.1.2) according to synopsis of tests given in
Table 4.

All external and internal loading of system shall be transferred safely from ETICS into loadbearing substrate.
Safety of complete system is determined by the weakest part of its composition: either by cohesion of used
solid components (esp. thermal insulation product) or by adhesion and coverage ratio and/or cohesion after
curing of used adhesive or paste components. Any change of any component can change achieved level
of resistance.

2.2.10 Resistance to embedded loads - resistance of mechanical fixing

Mechanical resistance to embedded loads of mechanically fixed ETICS with supplementary bonding (see
1.1.2.2.1) can be determined by one or more tests according to Annex H and/or Annex I selected according
to synopsis of tests of bond strength and wind load resistance given in Table 4.

In case of incapacity of bond resistance to transfer any inserted type of load from system into substrate
safely, the particular load shall be transferred from by mechanical fixing. The characteristic divides into two
details: conjunction of thermal insulation product with mechanical fixing device as the first and conjunction
of mechanical fixing device with substrate as the second. Level of the characteristic varies with changes of
respective characteristics of thermal insulation product, mechanical fixing device, substrate and/or
composition and construction of ETICS itself.

Resistance of mechanical fixing and evaluation of tests is to be performed by appropriate procedure


according to:
- 2.2.10.1 for ETICS fixed by plastic anchor(s) for ETICS (EAD 330196-01-0604) if pull-through
resistance at panel joints (Rjoint) can be determined by the pull-through test according to H.2 of Annex
H,
- 2.2.10.2 for ETICS fixed by plastic anchor(s) for ETICS (EAD 330196-01-0604) in case than
pull-through resistance at panel joints (Rjoint) cannot be determined by the pull-through test due to
unacceptable behaviour of test specimens during the test,
- 2.2.10.3 for ETICS fixed by plastic anchor(s) for ETICS (EAD 330196-01-0604) – anchoring in
substrate.

Final value of mechanical resistance according to 2.2.10.1 is to be obtained by calculation from relevant
type of resistance (Rpanel or Rjoint) and number of anchor used for area unit.

2.2.10.1 Resistance based on pull-through test of plastic anchor(s) for ETICS

Resistance based on pull-through test of fixings only is based on:


- pull-through resistance of single anchor placed at the middle of body of body of thermal insulation
product (Rpanel, see 1.3.10)
and
- pull-through resistance of single anchor placed at “T” panel joints (Rjoint, see 1.3.11) between bodies
of thermal insulation product.

Test of pull-through resistance of plastic anchor(s) for ETICS is to be performed on 5 test specimens at
least according to H.2 and Figure H2, scheme 2a of Annex H,. If type of installation of fixing can effect
measured values (e.g. countersunk assembly), test for each specified type of installation is to be performed
if necessary.

It is not recommended to determine Rpanel and/or Rjoint values by testing of thermal insulation products of
thickness higher than 80 mm 13. If necessary to test them, thickness tested has to be reported together
with value of displacement of anchor plate for possibility to be taken into account in evaluation of wind load
resistance of ETICS.

The average values of Rpanel (see 1.3.10) and/or Rjoint (see 1.3.11) in N per fixing in dry conditions and
average deformation in failure, are valid for configuration of ETICS given as: 14
- thermal insulation product of the same type with higher thickness and/or the same or higher thickness
and higher nominal tensile strength perpendicular to the faces,

13 According to achieved experience tests performed on higher thickness give although higher values of single
anchor resistance, but these higher values are achieved in very high deformations inappropriate for durability of
product.
14 Sometimes it may be suitable to give separate values Rpanel and/or Rjoint for more specific types of plastic anchors
for ETICS separately due to differences of their load bearing capacity and/or different behaviour of insulation
product on the same material basis.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 28/97

- anchors with the same or larger nominal plate diameter and the same or higher nominal plate stiffness
(see Annex M).

Following characteristics are given in the ETA:


- the average values, the minimal values and the estimations of standard deviation of Rpanel and/or
Rjoint in N per fixing in dry conditions,
- the average value at deformation in failure in mm,
- the material type and nominal value of thickness of thermal insulation product used for tests,
- average and minimum value of tensile strength perpendicular to faces of thermal insulation product
used for tests,
- the type(s), nominal plate diameter, nominal plate stiffness, type of installation (surface or
countersunk) and the characteristic value of resistance under tension load according to type of
substrate of single anchor NRk for type(s) of plastic anchors for ETICS used for tests (see 2.2.9.3) or
reference on type of mechanical fixing device (plastic anchors for ETICS), its harmonized technical
specification (i.e. EAD 330196-01-0604) and number of its European Technical Assessment,
- if countersunk assembly of anchor(s) is used (see 1.3.16), nominal thickness of thermal insulation
product between bottom edge of plate of anchor and back side of board of thermal insulation product,
(i.e. thickness non-effected by installation of anchor).

2.2.10.2 Resistance based on combination of pull-through test and static foam block test

Resistance based on combination of pull-through test and static foam block test applies if resistance at “T”
panel joints (Rjoint) (see 1.3.11) cannot be determined by the pull-through test due to unacceptable
behaviour of test specimens during the test).

This resistance is based on combination of tests according to Annex H, Figure H.2, scheme 2b and
calculation as follows:
- pull-through resistance of single anchor placed at the middle of body of thermal insulation product
(Rpanel, see 1.3.10)
and
- static foam block test according to H3 of Annex H,
and
- calculation of pull-through resistance of single anchor placed at “T” panel joints (Rjoint, see 1.3.11)
between bodies of thermal insulation product, as given below.

The test of pull-through resistance of plastic anchor(s) for ETICS placed at the middle of body of thermal
insulation product according to H.2 of Annex H, is to be performed on 5 test specimens at least (historical
data obtained from testing of 3 samples may be used – see H.2 of Annex H).

Than the test specimens for static foam block test are to be prepared with plastic anchor(s) for ETICS,
placed at the middle of body of thermal insulation product and in the “T” joints between them according to
Figure H.2., scheme 2b of Annex H. The test is to be performed according to H.3 of Annex H, at least on 3
test specimens for thermal insulation product.

When using the combination of tests described above (see Figure H.2, scheme 2b of Annex H), the
resistance Rjoint of anchors positioned at “T” panel joints is calculated then as:

Rjoint = (Fk – 2 × Rpanel) / 6

where:

pull-through test according to H.2 of Annex H (see 1.3.10),

device (plastic anchors for ETICS), its harmonized technical specification (i.e. EAD 330196-01-0604)
and number of its European Technical Assessment
- if countersunk assembly of anchor(s) is used (see 1.3.16), nominal thickness of thermal insulation
product between plate of anchor and back side of board of thermal insulation product (i.e. thickness
not effected by installation of anchor).

2.2.10.3 Pull-out resistance NRk of mechanical fixing devices (anchors) from substrate

Pull-out resistance NRk of mechanical fixing devices (anchors) can be determined and evaluated according
to EAD 330196-01-0604 for plastic anchors for ETICS if its value according to its manufacturer specification
is not available.

The shear strength and shear modulus of elasticity of thermal insulation product are to be tested and
evaluated according to EN 12090 – see Clause 2.2.5 of EAD 040065-00-1201.

2.2.14 Airborne sound insulation

The airborne sound insulation of ETICS is to be determined on the basis of laboratory tests carried out in
accordance with the standards EN ISO 10140-1, EN ISO 10140-2, EN ISO 10140-4 and EN ISO 10140-5
and evaluated in accordance with EN ISO 717-1.

2.2.14.1 Airborne sound insulation of ETICS

ETICS is to be tested on a basic wall with low coincidence frequency (heavy basic wall) specified by EN
ISO 10140-1 and EN ISO 10140-5. Single number improvement values ∆RW,heavy, ∆(RW + C)heavy and ∆(RW
+ Ctr)heavy are to be reported as evaluated according to EN ISO 10140-1, Annex G, and EN ISO 10140-5.
Meaning of stated quantities and indices see 1.3.18. This test covers the acoustic performance of ETICS
when combined with walls of low coincidence frequency with no abnormalities concerning their airborne
sound transmission and having a mass per unit area at least ten times larger than that of the ETICS.

ETICS designed for use with another type of basic wall not corresponding to the standard heavy basic wall
(e.g. hollow ceramics or cellular concrete) is to be tested on that type of wall. In such a case, the direct
difference of the weighted sound reduction indices of the wall with and without the ETICS, ∆RW,direct, ∆(RW
+ C)direct and ∆(RW + Ctr)direct, are to be reported as evaluated according to EN ISO 10140-1, Annex G
together with the description of the wall used for testing.

For the configuration of the ETICS to be tested, the following rules are to be taken into account:
- thermal insulation products with higher dynamic stiffness provide worse performance
- a higher number of fixings provides worse performance
- a higher adhesive surface coverage provides worse performance
- a higher mass of a rendering system provides better performance
- a greater thickness of the thermal insulation product provides better performance
- the performance for an thermal insulation product thickness between two tested ones can be linearly
interpolated
- anchors with plastic screws/nails provide better performance than with metal screws/nails

Single number improvement values ∆RW,heavy, ∆(RW + C)heavy and ∆(RW + Ctr)heavy or ∆RW,direct, ∆(RW + C)direct
and ∆(RW + Ctr)direct are to be calculated using following formulas:

∆RW,direct = RW,with – RW,without

∆(RW + C)direct = (RW,with + Cwith) – (RW,without + Cwithout)

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 32/97

∆(RW + Ctr)direct = (RW,with + Ctr,with) – (RW,without + Ctr,without)

References to symbols used see in 1.3.19.

The following extension rules are to be applied:


- the performance measured may also be used for heavier rendering systems than that measured (all
other parameters identical),
- the performance measured may also be used for the same type of thermal insulation product with
lower dynamic stiffness than that measured (all other parameters identical),
- if the performance has been measured with different thicknesses of thermal insulation product (all
other parameters identical) the values at an intermediate thickness can be obtained by linear
interpolation,
- the performance measured may also be used for the same type of thermal insulation product with
greater thickness than that measured (all other parameters identical),
- the performance measured may also be used for an ETICS fixed with fewer fixings than that
measured (all other parameters identical),
- the performance measured may also be used for an ETICS with lower bonded surface area than that
measured (all other parameters identical),
- the performance measured on the heavy wall (according to the definition in EN ISO 10140-5, Annex
B) may be used in extended application for all other heavy walls (of mass per square metre between
150 kg/m2 and 400 kg/m2).

Following characteristics are given in the ETA:


- airborne sound insulation as single number improvement value:
- ∆RW,heavy, ∆(RW + C)heavy and ∆(RW + Ctr)heavy for use with wall substrate corresponding to the
standard heavy basic wall walls of heavy type
and/or

bonded systems, see 1.1.2.1.1) and (if relevant) reference on its harmonized technical specification
(i.e. EAD 330196-01-0604) and number of its European Technical Assessment,
- nominal percentage of bonded surface, used for preparation of test specimen,
- type and characteristics (dimensions, density in kg/m², nature, design ) of wall(s) substrate used for

ANNEX A – REACTION TO FIRE - SPECIFIC TEST CONDITIONS

A.1. Common

The determination of reaction to fire of the ETICS is based on testing of “the critical case” - the most critical
configuration in sense of reaction to fire. According to the rules described further in the text, the
classification obtained on the most critical ETICS configuration is valid for all configurations having better
performance in sense of reaction to fire.

For the particular types of ETICS components the following principles apply:

- the base coat and finishing coat with the highest amount of organic content (related to the mass in
dried condition as in end use application) or the highest QPCS value (according to EN ISO 1716. 25)
shall be used for preparing the specimen,

- each decorative coat and key coat shall be tested unless it can be neglected according to the rules
below. If there are only differences in the amount of organic content but no difference in the organic
component itself, the decorative coat and the key coat with the highest organic content or the highest
QPCS value according to EN ISO 1716 25) of this organic component shall be tested,

- the decorative coat and/or the key coat can be neglected as long as they comply with the following:
26)

• the thickness of the decorative coat is less than 200 μm,

• and the content of organic components is of not more than 5 % (related to the mass in dried
condition as in end use application)

- In addition, each coat selected for testing according to the rules above before shall have the lowest
amount of flame retardants.

Product characteristics influencing the reaction to fire behaviour:

- Type of thermal insulation product (composition, thickness, density)

- Type of base coat and finishing coats (composition, thickness, mass per unit area)

- Type of key coats and decorative coats (composition, mass per unit area)

- Type of reinforcement (composition, thickness, mass per unit area)

- Type and nature of fixings

- Type and nature of fire breaks (interruptions to the continuity of insulation or any cavity

- The organic content of the binder and of any organic additive; this can be checked by providing the
formulation of the component, by performing suitable identification tests or by determining the glow
loss or net calorific value

- Type and amount of flame retardant intended to maintain or improve the reaction to fire performance
of the ETICS or its components and consequently of building elements to which they are applied.

Although the rest of this annex applies the “critical case scenario” for deciding what to test, it is accepted
that, where the manufacturer produces a range of ETICS having different overall classifications, he may
group these together into a number of different sub-groups (e.g. each sub-group corresponding to a
different overall classification) with the ‘critical case scenario’ being identified for each sub-group.

25) The manufacturer is responsible for the information on organic content per unit area and gross heat of
combustion (QPCS). If the information is not available, the QPCS value is tested to decide about the critical case.
26) This rule can be reconsidered when more experience and test result are available.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 46/97

Components of an ETICS, where these require separate assessment (as opposed to being tested as part
of the ETICS as a whole), which are classified A1 without testing according to Decision 96/603, as
amended, do not need to be tested.

If necessary, gross heat of combustion (QPCS) is to be determined according to EN ISO 1716.

A.2. Testing according to EN ISO 1182

This test method is relevant for the classes A1 and A2.

Using this test method, only the ‘substantial components’ of the ETICS need to be tested. ‘Substantial
components’ are defined by thickness ( 1 mm) and/or mass per unit area ( 1 kg/m2).

In the following, the thermal insulation product, the base coat and the finishing coat are identified as the
most significant ‘substantial components’, but the adhesive, the key coat, the decorative coat and any
reinforcement may also be ‘substantial components’.

Parameters relevant for this test method are:

- composition,

- density.

A.2.1 Thermal insulation product

For ETICS expected to be classified as A1 or A2, it is anticipated that only thermal insulation products with
reaction to fire class A1 or A2 will form the insulation layer. For testing the thermal insulation product
reference shall be made to the relevant product standards.

A.2.2 Render coatings

A.2.2.1 Base coats and finishing coats

The reaction to fire behaviour of base coats and finishing coats not falling under EC Decision 96/603/EC
(as amended) shall be tested according to the principle specified in § General.

The test result can be directly applied to all variants with the same base coat and finishing coat and with a
lower amount of organic components. When the subject of the directly applied result contains a flame
retardant, it shall be of the same type and its content shall be at least that of the product tested.

Differences concerning the density shall be considered by testing the lowest and the highest density.

A.2.2.2 Key coats and decorative coats

The principles specified in A.1 “Principle” shall be applied.

A.2.3 Adhesive

The same rules as given in A.2.2 above shall be applied.

A.2.4 Reinforcement

Each type of reinforcement that fulfils the requirements of a ‘substantial component’ shall be tested
according to EN ISO 1182. Reinforcement that is randomly dispersed (e.g. fibres) in the render shall be
tested as part of the render.

A.3 Testing according to EN ISO 1716

This test method is relevant for the classes A1 and A2.

This test method shall be performed to all components of the ETICS except for cases which are classified
as A1 without testing.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 47/97

Parameters relevant for this test method are: composition (when performing calculation of the QPCS-value,
density or mass per unit area and thickness are relevant). Mechanical fixings and ancillary materials which
are not continuous but discrete components of ETICS shall not to be considered for testing and for the
calculation of the QPCS.

A.3.1 Thermal insulation product

For testing the thermal insulation product, reference shall be made to the relevant product standards.

It is not realistic to require that each thermal insulation product of the same type is tested within the
classification of an ETICS. If the thermal insulation products come from different manufacturers and/or are
of different thickness, density and formulation from those used in the testing, these may be used subject to
the requirements of class A1 and A2 still being fulfilled.

It shall be proved by calculation (undertaken by responsible body) that the ETICS, together with the actual
thermal insulation product used in end use application, still fulfils the requirements concerning the QPCS -
value of product as the whole. For example, it is sufficient to determine the QPCS -value of the thermal
insulation material and if this is lower than the originally tested product then it is acceptable to use the
alternative insulation product instead of that used in the original test. 27

A.3.2 Render coating

In general, when performing calculations of the unit area referred QPCS-value (related to the surface) the
variant that provides the highest QPCS -value shall be considered.

The test shall be performed in accordance with the principles specified in A.1 General applied to each
component of the render coating.

It is not necessary to test a finishing coat with different grain sizes if the organic content is the same as or
lower than that of the tested coat.

The test results can be directly applied to all variants with the same render coating but with a lower amount
of organic components. When the subject of the directly applied result contains a flame retardant, it shall
be of the same type and its content shall be at least that of the product tested.

A.3.3 Adhesive

For the component adhesive of the ETICS, each product with a different formulation shall be tested for
reaction to fire behaviour by selecting the variant with the highest amount of organic components. The test
results can be directly applied to all variants with the same composition but lower amount of organic
components. For the case where one of the render coatings is used as the adhesive, the rules according
to A.3.2 shall be applied.

A.3.4 Reinforcement

Each type of reinforcement shall be tested according to EN ISO 1716. For reinforcement that is randomly
dispersed (e.g. fibres) in the render then it shall be tested as part of the render.

A.4 Testing according to EN 13823 (SBI-test)

This test method is relevant for the classes A2, B, C and D, in some cases also for A1. 28)

In this test procedure the complete ETICS shall be tested. The ETICS is fixed to a substrate as given in
Clause 5.3.2.2 of EN 15715. The fixing shall be made using either the adhesive used in the end use
application or, in the case of purely mechanical fixing, by using the means of mechanical fixing used in the
end use application. When adhesives are used, the test result is valid also for mechanical fixings.

27 ) Information relating to alternative insulation products of the same type to that originally tested may be evaluated
on the basis of the supplier's evidence provided within the context of its CE marking.
28) In cases according to Regulation (EU) 2016/364, Table 1, Footnote 2a; case A1 mentioned in EN 13501-1+A1
does not apply to ETICS.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 48/97

When a purely mechanical fixing with plastic anchors is used the test result is valid also for metallic anchors.

The maximum testable thickness of the test specimen, including a standard substrate according to EN
13238, is 200 mm. However, in practice, for many ETICS, the total overall thickness may be greater than
200 mm. In such cases, using a standard substrate, the thickness of the thermal insulation product shall be
reduced to provide for the maximum specimen thickness of 200 mm. Results obtained on an ETICS at 200
mm thickness are accepted for greater thicknesses.

The test specimen consists of a corner construction which shall be representative of the construction in
practice. All edges are covered with the rendering system excluding the bottom edge and the top of the
specimen. The floor of the test trolley beneath the test specimen can be covered by an aluminium foil (see
figure A.1).

It is recommended to:

- either prepare the specimens at the lab and then put it onto the trolley (with the foil on)

or

- the manufacturer builds the wall at the factory and carries it to the lab where it is put onto the trolley.

After preparation of the test specimens they shall be conditioned according to EN 13238.

Parameters which are relevant:

- amount of adhesive

- type, thickness and density of thermal insulation product

- type, binder and thickness of each coat of render coating

- amount of organic content of each coat of render coating

- amount of flame retardant of each coat of render coating

- type of reinforcement

In principle, it is desirable to find the test specimen configuration that gives the critical case concerning the
reaction to fire test results. In the test procedure according to EN 13823, values for the rate of heat release,
total heat release, lateral flame spread, rate of smoke release, total smoke release and burning droplets
are determined. Due to the possible effects of the thermal insulation product, the following proposals are
divided by considering separately the testing of ETICS with class A1 and A2 thermal insulation products
and the testing of ETICS with class B, C, D and E thermal insulation products.

A.4.1 Thermal insulation product

For the testing of ETICS with thermal insulation products with reaction to fire class A1 or A2 the thermal
insulation product with the highest thickness, the highest density (with a tolerance of ±10 %) and the highest
organic content (related to the mass in dried condition) has to be used for preparing the test specimen. The
reaction to fire classes A1 or A2 of the thermal insulation product shall be proven separately. 29)

For the testing of ETICS with thermal insulation products with reaction to fire class B, C, D or E, each type
of thermal insulation product shall be tested within the system. For each type of thermal insulation product
the thermal insulation product with the highest thickness and the highest density (with a tolerance of 10 %)
shall be used for preparing the test specimen. The reaction to fire class B, C, D or E of the thermal insulation
product shall be proven separately. 29)

29) In some Member States requirements might exist to demonstrate the behaviour of products with respect to
continuous glowing combustion in the case of fire. The mandates for the product standards, therefore, are
currently under revision. Additional national assessment e.g. on the basis of national procedures to demonstrate
this behaviour might be required until a European harmonised procedure is available.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 49/97

Annex A of EAD 040065-00-1201, for choosing the samples and executing the relevant reaction to fire tests
shall be applied.

For testing ETICS which are mounted onto the substrate by using an adhesive (only bonded or
mechanically fixed and bonded) three specimens shall be prepared and tested

- with the highest thickness of the thermal insulation product in cases where the adhesive has an
organic content of equal to or less than 15 % (related to the mass in dried condition and in end use
application) and

- with the highest and the lowest thickness of the thermal insulation product in cases where the
adhesive has an organic content of more than 15 % (related to the mass in dried condition and in
end use application).

A.4.2 Render coatings

By testing one specific render coating representing a range of different coats, the following rules shall be
applied to discriminate the composition, which is able to represent a range of coats:

- The base coat, the key coat, the finishing coat and the decorative coat to be used for preparing the
specimen, taking account of the permissible combination(s) allowed by the manufacturer, shall be
determined in accordance with the principles specified in A.1. General.

- For a base coat and a finishing coat having an organic content less than or equal to 5 % (related to
the mass in dried condition as used in the end use application), only the lowest thickness needs to
be used for preparing the test specimen.

- For a base coat or a finishing coat having an organic content higher than 5 %, both the lowest and
the highest thickness of the layer of the base coat and finishing coat shall be used for preparing the
test specimens.

Regardless of the organic content, only the highest thickness of a base coat and a finishing coat shall be
tested on insulation material with class A1 or A2-s1, d0.

When the only difference in coatings is thickness and it is 0,5 mm or less, the coatings may be considered
to be the same.

A.4.3 Adhesive

The influence of the type of adhesive having an organic content of equal to or less than 15 % (related to
the mass in dry condition) is assumed to be negligible. Only the amount of organic content is considered
important. Therefore, an adhesive with the highest amount of organic content should be used for preparing
the test specimens applied at the maximum thickness.

The influence of adhesives having an organic content of more than 15 % cannot be assumed to be
negligible. Therefore, each type of adhesive with a different composition shall be tested by selecting the
variant with the highest organic content.

A.4.4 Reinforcement

The specimens shall be prepared with the reinforcement that is intended to be used in end use application.
If different reinforcements are intended to be used, the reinforcement with the highest QPCS-value per unit
area shall be used for preparing the SBI specimen. At the long wing of the SBI specimens a vertical joint of
the reinforcement shall be included at a distance of 200 mm away from the inner corner of the specimens
by 100 mm overlapping of the two layers of the reinforcement (that means the joint begins at a distance of
150 mm and ends at a distance of 250 mm away from the inner corner). The test results from a system with
an overlap of the reinforcement of 10 cm are valid for all joints with an overlapping of 10 cm or more.

A.4.5 Application of test results

The test result is valid for:

- thermal insulation products:

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 50/97

• of the same type,

• with lower density,

• with lower thickness or between those evaluated in the tests, provided that the worst result of
the two thicknesses tested is used for intermediate thicknesses,

• with equal or less organic content,

- base coats and finishing coats:

• with equal or less organic content,

• with equal or greater content of the same type of flame retardants,

• with equal or greater thickness if the organic content is equal to or less than 5 %,

• with thickness between those evaluated, provided that the worst result of the two thicknesses
tested is used for intermediate thicknesses

- key coats:

• with equal or less organic content,

• with equal or greater content of the same type of flame retardants,

- decorative coats:

• with equal or less organic content per unit area,

• with equal or greater content of the same type of flame retardants,

- adhesives:

• with equal or less organic content and equal or less thickness if the organic content is equal to
or less than 15 %,

• of the same type, with equal or less organic content and equal or less thickness if the organic
content is greater than 15 %,

- reinforcements:

• with an equal or lower QPCS-value per unit area.

A.5 Testing according to EN ISO 11925-2

This test method is relevant for the classes B, C, D and E.

In this test procedure, the ETICS is tested without using a substrate. The maximum thickness of the test
specimen is 60 mm. In cases where the thickness of the ETICS is larger than 60 mm, the thermal insulation
product may be reduced for the purposes of testing. The results from the testing of specimens at 60 mm
are applicable to greater thicknesses.

Parameters which are relevant:

- type and amount of adhesive,

- type, thickness and density of thermal insulation product

- type, binder and thickness of each coat of render coating

- amount of organic content of each coat of render coating

- amount of flame retardant of each coat of render coating

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 51/97

- type of reinforcement.

The specimens are prepared in such a way that the edges are not covered with the rendering system (cut
edges). The tests are performed with surface flaming of the front side and possibly edge flaming of the test
specimen turned by 90° according to the rules of standard EN ISO 11925-2.

A.5.1 Thermal insulation product

A thermal insulation product, representative in its characterisation (type, reaction to fire classification and
density) for the end use application shall be used. The ETICS shall be evaluated incorporating the thermal
insulation product at the highest possible thickness and the highest and the lowest possible densities.

For ETICS with thermal insulation products classified class E, the test results are valid only for the thermal
insulation products as used in the test. Manufacturer has the possibility of using thermal insulation products
from different manufacturers when the following additional tests are performed and conditions are fulfilled
or the manufacturer provides the necessary evidence. For thermal insulation products, it shall be proven
separately that the product fulfils the requirements for reaction to fire class E.

Annex A of EAD 040065-00-1201, for choosing the samples and executing the relevant reaction to fire tests
shall be applied.

A.5.2 Render coatings

For testing one specific rendering system representing a range of different coats, the rules as mentioned in
A.4.2 apply.

A.5.3 Adhesive

For adhesives (mortars) having an organic content of equal to or lower than 15 % (related to the mass in
dried condition) it can be assumed that they fulfil the requirements of the class B without testing according
to EN ISO 11925-2. Therefore, no need exists to take into account such adhesives for preparing and testing
specimens of ETICS according to this standard.

For adhesives having an organic content of more than 15 % (related to the mass in dried condition) it is
necessary to carry out a complete set of six additional tests on specimens turned at 90 degrees on their
vertical axis with edge exposure of the adhesive layer. The specimens consist of the substrate, the adhesive
and the thermal insulation product. The following rules shall be applied for preparing the specimens.

- Each type of adhesive with a different composition shall be used by selecting the variant with the
highest amount of organic content and with the highest thickness.

- The thermal insulation product shall be used with the lowest thickness applied for the assessment.

- The substrate shall be the same as the one used for SBI testing of the ETICS as a whole.

A.5.4 Reinforcement

The specimen shall be prepared with the reinforcement intended to be used in end use application. If
different reinforcements are intended to be used, the reinforcement with the highest QPCS-value per unit
area has to be tested.

A.5.5 Application of test results

The test result covers end use application arrangements with the same type of thermal insulation product
(excluding insulation made of polystyrene classified as reaction to fire class E) as used in the tests with
thicknesses and densities as described in A.5.1 and equal or lower organic content.

The test results from tests with thermal insulation products made of polystyrene classified class E are valid
for ETICS with thermal insulation products as used in the test or for ETICS with any polystyrene thermal
insulation products classified class E when the test evidence according to A.5.1 was provided.

For the direct application of test results regarding base coat, key coat, finishing coat, decorative coat,
reinforcement and adhesive the same rules shall apply as given in clause A.4.5.

ANNEX B – WATER ABSORPTION TEST


B.1 Common

These tests have 3 purposes, to determine:

- the water absorption, in order to assess according to 2.2.2 further process of testing,

- which finishing coats should be applied on the rig to be subjected to hygrothermal test on the rig,

- whether the freeze-thaw testing described in Annex D is necessary.

B. 2 Preparation of the samples


Samples are prepared each by taking a piece of the specified thermal insulation product. Surface area to be at
least 200 mm x 200 mm. Samples are applying in accordance with the manufacturer’s instructions, e.g. thickness,
mass per unit area and method of application, both:

- the reinforced base coat alone

and

- all the configurations of complete rendering systems proposed by the manufacturer, i.e. reinforced
base coat covered with each type of finishing coat and (associating or not) key coat and/or decorative
coat. If the application of the key coat and/or the decorative coat is optional, at least configurations
without them shall be tested.

Within a type of finishing coat, the test shall be carried out with at least the thickest layer (generally higher particle
size grading with floated finishing aspect).

Three samples are prepared for each configuration. Quantities and/or thicknesses applied shall be recorded as
well as identification of the render’s components according to Annex L.

The edges of the samples the thermal insulation product included are sealed against water to ensure that during
subsequent testing only the face of the reinforced base coat or the rendering system is subjected to water
absorption. After preparation the samples are conditioned for at least 7 days, but no more than 10 days at (23 ±
2) °C and (50 ± 5) % RH.

After conditioning the test samples are subjected to a series of 3 cycles comprising the following phases:

- 24 h immersion in a water bath (tap water) at (23 ± 2) °C. The samples are immersed rendered face
downwards, to a depth of 2 to 10 mm, the depth of immersion dependent upon surface roughness. To
achieve complete wetting of rough surfaces, the samples shall be tilted as they are introduced into the
water. The depth of immersion can be regulated in the water tank by means of a height-adjustable slat.

- 24 h drying at (50 ± 5) °C.

If interruptions are necessary (e.g. at week-ends etc.) the samples are stored at (23 ± 2) °C and (50 ± 5) % RH
after the drying at (50 ± 5) °C.

After the cycles the samples are stored for at least 24 h at (23 ± 2) °C and (50 ± 5) % RH.

B.3 Capillarity test procedure:

To start the capillarity, test the samples are again immersed in a water bath as described above.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 56/97

The samples are weighed after 3 minutes’ immersion in the bath and weight is recorded as reference mass with
accuracy in 0.1 g.

The samples are immersed for 1 hour and then for 24 hours in total. After both of periods they are removed, the
surface of the samples is dried with a damp sponge cloth carefully and samples are weighted. Their weight is
recorded again.

B.3 Analysis of test results:

Calculation is undertaken to determine the mean (average) water absorption of the three samples per square
meter after 1 and 24 hours. The outcome of these results will determine the following:

- Necessity of further testing of water absorption of the reinforced base coat with finishing coat and key
coat / decorative coat respectively according to this EAD:

If the water absorption of the reinforced base coat after 1 hour is equal to or more than 1 kg/m2,
the water absorption after 1 hour of each rendering system shall be tested.

- Hygrothermal behaviour:

For the choice of the finishing coats to be applied on the rig, see 2.2.5.1,

- Freeze-thaw test:

For the choice of the finishing coats see 2.2.5 and Figure 1.

The freeze-thaw test (see 2.2.5 and Figure 1) shall be performed if the water absorption of either
the reinforced base coat or the rendering coating is equal to or more than 0.5 kg/m2 after 24
hours.

Note: In order to provide information about the stabilization for some ETICS the water absorption measured can be plotted
on a chart as a function of t.

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 57/97

ANNEX C – TESTS OF WATER VAPOUR PERMEABILITY

C.1 Common

Within a type the test has to be carried out with the thickest continuous layer (generally higher particles size
grading with floated finishing aspect).

C.2 Samples

The samples are prepared by applying the rendering to the thermal insulation product in accordance with the
manufacturer’s instructions and conditioned for at least 28 days at (23 ± 2) °C and (50 ± 5) % RH. Quantities
and/or thicknesses applied are to be recorded as well as density of hardened base coat, particle size grading of
base coat and finishing coat and ash content of base coat, finishing coat, key coat and decorative coat (if used).

Than five test samples of at least 5000 mm2 are obtained by separating the rendering system from the thermal
insulation product.

C.3 Test procedure

The test is carried out on the rendering system in accordance with EN ISO 12572.

The test is to be carried out in according to Test conditions set C, wet state, aqueous solution of of ammonium
dihydrogen phosphate (NH4H2PO4).

C.4 Result of test

The results are expressed as water-vapour diffusion-equivalent air layer thickness in metres (of air) and the
resistance to water vapour diffusion is determined as the mean value of measured specimens.

The value of water-vapour diffusion-equivalent air layer thickness in metres (of air) is to be stated on the tested
rendering system(s) with precision corresponding to enable the designer to evaluate the risk of interstitial
condensation.

Usually the result of tests is to be rounded to 1/10 m (one decimal).

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 58/97

ANNEX D – FREEZE-THAW TESTS


D.1 Freeze-thaw test of rendering - Common

Freeze-thaw resistance of the ETICS is considered as acceptable if the water absorption of both the
reinforced base coat and the rendering system is less than 0.5 kg/m² after 24 hours.

In all other cases the following test of freeze-thaw shall be performed.

The test shall be carried out on three samples 500 mm x 500 mm consisting of a piece of the specified
thermal insulation product covered by:

- reinforced base coat without finishing coat if its water absorption is equal to or higher than 0.5
kg/m2 after 24 hours,

- all the configurations of rendering systems proposed by the manufacturer (i.e. reinforced base
coat covered with each type of finishing coat and (associating or not) key coat and/or decorative
coat which lead to a water absorption equal to or higher than 0.5 kg/m2 after 24 hours. If the
application of the key coat and/or the decorative coat is optional, at least configurations without
them shall be tested.

These samples are prepared according to the manufacturer’s instructions and then stored for at least
28 days at (23 ± 2) °C and (50 ± 5) % RH.

If the thermal insulation board has one dimension at least smaller, the test can be performed on square
specimens of smaller dimensions. Dimensions of test specimen in that case are to be given in the ETA.

Quantities and/or thicknesses applied shall be recorded as well as related characteristics of the render’s
components according to Annex L.

D.2 Cycles

Than the samples are subjected to a series of 30 cycles (one cycle lasts for 24 hours) comprising of:

- exposure to water for 8 hours at initial temperature of (23 ± 2) °C by immersion of the samples,
render face downwards in a water bath, by the method described in Annex B (water absorption
test),

- freezing to (-20 ± 2) °C, fall to prescribed temperature for 5 hours measured at the sample surface
or for 2 hours measured in the conditioned air, standing for 11 and 14 hours respectively, total of
16 hours. The regulation is to be obtained by conditioned air.

Starting the test samples are manually inserted in water bath as prescribed. After their conditioning they

The purpose of the test is to determine the longitudinal displacement of the ETICS at the edges of the
wall.

G.2 Preparation of samples

The test is performed with the thinnest thermal insulation product envisaged to be covered by the ETA.
A reinforced concrete slab measuring 1.0 m × 2.0 m with a thickness of 100 mm is prepared with a
smooth surface.

A small layer of sand is placed on top of the slab to allow the insulation panel to slide. Three (2 + 2/2)
insulating boards are applied to the concrete slab with tight butt joints as illustrated in Figure G.1. The
ETICS shall be fixed with the minimum number of mechanical fixing devices according to the
manufacturer’s instructions.

> 1000

> 500 > 500 > 500

Figure G.1 Arrangement of insulation boards in displacement test

The reinforced base coat is then applied to the thermal insulation product according to the
manufacturer’s specification. The reinforcement shall protrude on all sides of the slab by about 300 mm.

The rendering shall be cured for at least 28 days at (23  2) ºC and (50  5) % RH.

Before testing, a foam block is bonded to the cured rendering; the protruding ends of the reinforcement
are then fixed to the clamping jaws over their full length.

G.3 Execution of test

A simulated wind suction load of 2 000 Pa is applied to the ETICS via the foam block and glued plywood
or other rigid panel. Principle for preparation of test is illustrated in Figure G.2

Simultaneously a normal tensile load is applied to the rendering of the ETICS via the clamped-in
reinforcement. At a tensioning speed of 1 mm/min the displacement of the ETICS relative to the concrete
slab and the corresponding load is measured and recorded.

Preferably the concrete slab is placed on top and the ETICS is applied under the slab.

ANNEX H – PULL-THROUGH TESTS


H.1 Common

The purpose of the test is to determine the working diagram and failure load in pull-through of anchor
through thermal insulation product.

The pull-through test can be performed in dry conditions in two possible configurations according to
assessed ETICS specification:

- with anchors placed at the body of the thermal insulation product (Rpanel) – see 1.3.9 and Figure
H.1

and

- with anchors placed at the panel joints (Rjoint) – see 1.3.11 and scheme 2a on Figure H.2

It is not recommended to determine Rpanel or Rjoint values by testing of thermal insulation products of
thickness higher than 80 mm. These values have to be reported together with information about
displacement so that they can be taken into account in assessment of wind load resistance of an ETICS.

If ETICS is specified with thermal insulation product of thickness higher than 80 mm only, effect of
thickness on Rpanel and Rjoint values shall be considered in evaluation.

H.2 Pull-through test of anchors

The pull-through test of anchors is not required if the ETICS is a bonded one with anchors used as
supplementary device only (see 1.1.2.1.2).

The test is to be performed in dry conditions.

Samples consisting of board of thermal insulation product of dimensions 350 mm × 350 mm with an
anchor driven through the centre of each sample (or at panel joints as described at Figure H.1 and
Figure H.2), are bonded, using a suitable adhesive, to a rigid substrate (see Figure. H.3). The head of
the anchor is covered previously with a self-release sheet.

When the adhesive has cured, a pulling force is exerted, at a loading rate of 20 mm/min between the
rigid plate and the end of the anchor protruding through the thermal insulation product until failure.

5 or more tests depending on the variance of test results shall be carried out. However, historical data
obtained from testing of 3 samples can be used on responsibility of TAB.

according to the standard production size of the thermal insulation product using the minimum thickness.

Test samples shall be prepared in accordance with the manufacturer’s instructions on position of
anchors and/or profiles and taking into account the influence of the anchors and/or profiles positioned
at the panel joints.

For thermal insulation product based on EAD 040065-00-1201, 3 or more tests (depending on the
variance of test results) shall be carried out.

Figure H.4 Test set-up for the static foam block test

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 73/97

Test details are illustrated in Figure H.4. The testing load F is generated by a hydraulic jack and
transferred via a load cell to plywood or other rigid panel of sufficient stiffness. The loading speed shall
be in the order of 10  1 mm/min.

Plywood or other rigid panel is connected to a base coat of tested specimen by foam blocks glued on
both sides by appropriate adhesive. The foam blocks shall be weak enough to follow all displacements
of the coating without affecting the bending stiffness of the ETICS. Therefore, the blocks are cut to
rectangular pieces not exceeding 300 mm × 300 mm in width. The height of the blocks shall be at least
300 mm. 1)

As the surface of the sample is not directly accessible, the displacement of the render surface is
measured via an extension rod passing through a hole in one of the foam blocks.

The test is carried out to failure in dry conditions.

Test report on static foam block test shall contain at least:

- registered data of the stages of the installation:

• the date and time of the various stages

• name and production lot of the components

• way of base coat preparation (tool, % of mixing, possible pause time before application, …)
as well as their way of application (hand tool, machines, number of layers, …)

• tensile strength perpendicular to the face of the thermal insulation product tested

• quantities and/or thickness of base coat applied per square metre

• quantities, position and type of anchors and/or profiles used

• any other information meaningful for the test and its result.

- registered values of displacement and failure load during the test.

1) A suitable initial length of the foam block elements is 500 mm. The foam blocks can be cut off with a hot wire
after the test is finished. They may be reused at least 20 times until the remaining length reaches about 300
mm.
The tensile strength of the foam material shall be in the range of 80 - 150 kPa, the rupture strain shall exceed
160 %. The compressive strength according to ISO 3386-1 or -2 shall be in the order of 1,5 - 7,0 kPa. An
example of a suitable material is polyether foam.

European Assessment Document – EAD 040759-00-0404 74/97

ANNEX I – HYGROTHERMAL TEST ON THE RIG


I.1 Common

Hygrothermal test on the rig is to be performed as a part of determination of watertightness of ETICS


according to 2.2.6.
Based on the outcome of the water absorption test (see 2.2.3) the specification of the product to be
tested is specified (see 2.2.5 and Figure 1).
Accompanying samples are prepared at the same time as the rig in order to evaluate the following
characteristics after heat/rain and heat/cold cycles (for sample size and number: see relevant test
method):
- bond strength between the base coat and thermal insulation product – only if the low part of the
rig does not only consist of the reinforced base coat alone, i.e. ETICS with only one finishing coat)
(see F.5 of Annex F)

- Tensile strength and elongation at break (see L1.3.2 of Annex L,) – only for products with an
application thickness up to 5 mm.

In the case of reinforced base coat with a thickness greater than 5 mm complementary samples shall
be prepared also to perform the test on the hardened product according to L.1.3.1 of Annex L.

I.2 Principles related to the preparation of the rig

- As a general rule, only one reinforced base coat and at the very most four finishing coats in vertical
divisions can be applied per one rig.

- If several adhesives are proposed for the ETICS, only one with the lowest bond strength between
adhesive (mortar or paste) and thermal insulation product (see F.3 of Annex F) shall be tested on
the rig.

- If more than 4 finishing coats are proposed for the ETICS, the maximum number of coats,
representative of the different types proposed, shall be tested on rig(s). Furthermore, if the water
absorption of the reinforced base coat after 24 h is equal to or more than 0.5 kg/m² (see 2.2.2),
each type of finishing coat containing a pure polymeric binder (non cementitious) shall be
submitted to hygrothermal cycles on rig(s). Any finishing coats not tested on the rig shall be
examined according to 2.2.16.1 and F.5 of Annex F.

- If different finishing coats can be used in the ETICS, the lower part of the test rig (height of 1.5 x
insulating panel width) consists of the reinforced base coat only without any finishing coat.

- If several ETICS differ only in the method of fixing (bonded or mechanically fixed) of the thermal
insulation product, the test is only carried out on the ETICS applied with adhesive at the edge of
the rig and with mechanical fixings devices in the centre.

- If several ETICS differ only in the type of thermal insulation product, two thermal insulation
products can be applied to the rig. The thermal insulation products are divided vertically at the
centre of each rig.

- The ETICS is applied, in accordance with the manufacturer’s instructions, to a sufficiently


stabilized masonry or concrete substrate.

- The ETICS shall also be applied to the lateral faces with a uniform maximum thickness of thermal
insulation product of 20 mm. If the thermal insulation product is not available in this thickness, the
lateral faces can be covered with a thickness of 20 mm expanded polystyrene.

- Thermal insulation product requiring stabilization (prescribed delay between production and sale)
shall be no older than 15 days beyond the minimum specified period.

The dimensions of the rig shall be:

• total surface ≥ 6 m2

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 75/97

• total width ≥ 2.50 m

• total height ≥ 2.00 m.

A rectangular opening (consisting of the absence of the ETICS on the substrate at this area) is included
at the corner of the rig, 0.40 m wide by 0.60 m high, positioned 0.40 m from the edges according to
Figure I.1.

ANNEX J – THERMAL RESISTANCE


The additional thermal resistance provided by the ETICS (RETICS) to the substrate wall is calculated from
the thermal resistance of the thermal insulation product (Rinsulation) determined in accordance with the
appropriate hEN or EAD for the relevant thermal insulation product, and from either the tabulated Rrender
value of the render system (Rrender may be calculated as 0.02 m2.K/W or Rrender determined by test
according to EN 12667 or EN 12664 depending on expected thermal resistance) according to equation:

RETICS = Rinsulation+ Rrender [(m²K)/W]

as described in EN ISO 6946 and EN ISO 10456.

If the thermal resistance cannot be calculated, it can be tested on the complete ETICS as described in
EN 1934.

The thermal bridges caused by mechanical fixing devices influence the thermal transmittance of the
entire wall and shall be taken into account using the following equation:

Uc = U + ΔU [W/(m²K)]

where:

ANNEX K - RENDER STRIP TENSILE TEST


K.1 Common

This test is determined for the evaluation of the crack behaviour of the reinforced base coat by
determination of the crack width distribution and the "characteristic crack width" Wrk at completed
cracking.

K.2 Preparation of test sample

A render strip sample has the size 600 mm × 100 mm × dr and consists of the reinforcement and the
base coat. “dr ” is thickness of the base coat with embedded reinforcement.

The reinforcement with a length of 800 mm is arranged within the base coat according to the
manufacturer’s instructions. It shall protrude about 100 mm at both ends. The protruding parts of the
reinforcement are placed on the render surfaces on which two metal plates are glued by appropriate
glue.

If the reinforcement is not in the middle, two strips shall be glued to a double symmetrical specimen
where the thinner parts of the strips are in the middle of the specimen.

As an alternative to bonding the specimen between two steel plates the fixing of the test sample can be
done using a PVC foil (thickness 1.5 to 2.0 mm, Shore-A-hardness 82) and pneumatic/hydraulic
clamping device (see Figure K.1).

The test is performed in warp and weft direction on three render strips each. The number of threads in
one direction shall be the same for all the three strips.

Figure K.1 Test set-up for the render strip tensile test

K.3 Test procedure

The tensile loading is applied in deformation-controlled mode with a rate of strain of 0,5 mm/min. The
loading is measured via a static uniaxial tensile testing machine of class 1 according to EN ISO 7500-1.
The displacements are measured by two electronic displacement gauges for ± 2.5 mm, precision class
0.1 (e.g. of DD1 type).

©EOTA 2021
European Assessment Document – EAD 040759-00-0404 81/97

The length of the measuring distance shall amount to at least 100 mm. The measuring points shall be
arranged such that they are at least 75 mm off the outer limits of the load introducing elements. The
gauge length shall be 150 mm and such that it is at least 75 mm away from the peaks of the metal
plates. The two electronic displacement gauges are fixed the same way on the front and backside and/or
the face sides of the specimen with the possibility of a separate analysis of the measurement results.

The render strips are loaded 10 times up to 50 % of the crack strength expected, for organic rendering
systems up to a maximum of 250 N per test strip. Loading and release shall last about 1 to 2 minutes.
During the 11-th cycle the render strips are loaded until cracking and subsequently until failure.

If no early failure occurs, the loading process is interrupted at render strain values of 0.3 %, 0.5 %,
0.8 %, 1.0 %, 1.5 %, and 2.0 %. The quantity of cracks within the measured range is counted and
recorded. The crack width shall be classified with the frequency occurred in the crack developing record
(see Table K.1) in categories of ≤ 0.05 mm, ≤ 0.10 mm, ≤ 0.15 mm, ≤ 0.20 mm, ≤ 0.25 mm, and
> 0.25 mm. The maximum crack width Wmax measured in each case shall be recorded with an accuracy
of 1/100 mm.

It is recommended to measure the crack width with a magnifier with fiftyfold magnification; an
exaggerated preciseness is not appropriate due to the irregularities of the cracks.

K.4 Analysis of test results

K.4.1 Exact procedure (I)

The related constituent equations are derived from the recorded load-strain diagram for the warp and
weft direction. The render strain εrk with completed cracking can be read from that. For this state of
expansion, however, at least at 0.5 % expansion the characteristic crack width wrk is determined from
all the test results on hand as 95 % quintile with 75 % confidence level in the specified operational steps
following hereinafter. In doing so intermediate values can be interpolated linearly:

- determination of the strain εrk with "completed cracking" (constituent equations derived from the
load-strain diagrams); εrk  0,5 %,

- number of sample sides and measured crack widths per render tension state from the recorded
crack developing record (see Table K.1),

- determination of the mean value of the crack widths wm,I measured at expansion state εrk of the
"completed cracking". In addition, it is possibly necessary to consider the next higher and lower
state and to linearly interpolate the crack widths measured,

- for the mean value wm,I determined of the crack width the respective standard deviation  is
determined,

- depending on the number of tests and the confidence level of 75 % for experimental analyses on
ETICS the kn value for the 95 % quantile results from statistical data according to Clause D.7.2,
Annex D of EN 1990, according to equation:

wrk = wm,I + ( × kn)

where

K.4.2 Simplified procedure (II)

The characteristic crack width for ε'rk = 0.8 % is determined as 95 % quantile with 75 % confidence level
in the specified operational steps following hereinafter.

- determination of the mean value of the crack width wm,II at tension stat’ ε'rk = 0.8 %.

- for the mean value wm,II determined of the crack width the respective estimation of standard
deviation  is determined.

- depending on the number of tests and the confidence level of 75 % for experimental analyses on
ETICS the kn value for the 95 % quantile results from statistical data according to Clause D.7.2,
Annex D of EN 1990 according to equation:

wrk = wm,II + ( × kn)

For organic rendering systems without observed crack width the elongation at rupture εru and the
respective ultimate load Nru shall be determined as a mean value from each of the individual tests.

ANNEX L – TESTS ON COMPONENTS
L.1 Common

These test methods shall be applied where tests of components used for assessment of ETICS are
necessary for evaluation of achieved level(s) of performances of ETICS in relation to real level(s) of
characteristics of components used for tests.

In some cases, such as where a specification of performances of component is sufficient to identify its
characteristics, the identification tests do not need to be performed as far as the component is identified
according to its harmonized specification by means such and its trade name.

L.1 Adhesives, base coats, key coats and finishing coats

L.1.1 Product as delivered

The following tests are performed on homogenised and unmodified products.

L.1.1.1 Density

Pastes and liquids:

This is measured at (23 ± 2) °C in a 100 cm3 or 1000 cm3 cylinder.

Powders:

This is measured at (23  2) °C in a 500 cm³ cylinder.

L.1.1.2 Dry extract (only pastes and liquids)

L.1.1.2.1 Lime and polymer based products

This is determined after placing the sample in a ventilated oven set at (105 ± 5) °C until a constant mass
is obtained.

The mass is regarded as constant if the difference in mass between two successive weightings, one
hour apart, does not exceed 0.1 g.

Initial weighing for testing:

- 2 g for liquid products (impression, etc. ...),

- 5 g for products in paste form.

The results are expressed as a percentage relative to the initial mass (mean value of 3 tests).

L.1.1.2.2 Silicate based products

L.1.1.3 Ash content

Pastes and liquids:

The ash content is determined on the same samples as those on which the dry extract has been
measured.

Powders:

The ash content is determined at 450°C and 900°C on a sample of approximately 5 g pre-dried at
(100 ± 5) °C or at (200 ± 5) °C for silicate based products, to constant mass. The mass is regarded as
constant if the difference in mass between two successive weightings, one hour apart, does not exceed
0.1 g.

Method of operation:

- The sample is placed in a tarred crucible either fitted with a lid or enclosed in a leak-tight
container and the whole is weighed,

- After the lid has been removed, where necessary, the crucible is placed in the oven maintained
at ambient temperature,

- The temperature of the oven is then raised to (450 ± 20) °C (ash content at 450 °C) or to
(900 ± 20) °C (ash content at 900 °C) and maintained at that temperature for 5 hours,

- The crucible is allowed to cool down to room temperature in the desiccators before being
weighed.

The results are expressed as a percentage relative to the initial mass after drying (mean value of 3 tests).

Note: The tolerances at 900 °C may become larger, taking account of the products' composition.

L.1.1.4 Particle size grading

Pastes:

Particle size grading is established from a sample of fillers removed from the manufactured product after
washing on a sieve, mesh size 0.08 mm or after any other suitable and pertinent preparation.

sieves.

L.1.2 Fresh mortar

L.1.2.0 Preparation of mortar

The mortar is prepared in the laboratory using a concrete mixer (pan type) in accordance with EN 196-1.
Draft EAD – European Assessment Document EAD 040759-00-0404, yyyy-mm adopted/final 85/97
EOTA file № 17-04-0759-04.04

The tests are carried out immediately after mixing unless otherwise specified by the manufacturer
(possible delay time necessary prior to application).

L.1.2.0.1 Dry mortar

- 2 kg of powder is poured into the container and the required amount of water as specified by
the manufacturer is added,

- The whisk is turned manually a few times to clear the path of the mixer,

- The material is mixed for 30 seconds at low speed,

- The walls of the container are scraped and powder gathered on the whisk is detached with
a spatula, if necessary,

- The material is mixed again for 1 minute at low speed.

L.1.2.0.2 Paste requiring addition of cement and powder requiring addition of extra binder

- For pastes 1 liter of paste is poured into the container and the amount of cement prescribed
by the manufacturer is added.

- For powders 2 kg of powder is poured into the container and the amount of extra binder
prescribed by the manufacturer is added.

- the whisk is turned manually a few times to clear the path of the mixer,

- the material is mixed for 30 seconds at low speed,

- the walls of the container are scraped and powder gathered on the whisk is detached
with a spatula, if necessary,

- the material is mixed again for 3 minutes at high speed.

L.1.2.0.3 Ready to use paste

Pastes have to be homogenized before use.

L.1.2.1 Water retention capability

Water retention capability is determined for the fresh mortar, mixed as detailed in L.1.2.0.

The test is performed using the apparatus described in the standard ASTM C.91. The mortar is subjected
to vacuum for 15 minutes as follows:

- For base coat and finishing coat(s) (except coat(s) whose binder is pure polymeric), the
vacuum applied is 50 mm Hg (pressure difference between the exterior and the interior
of the container) (see Figure L.1.)

- For adhesives, the residual pressure is 60 mm Hg (absolute pressure inside the


container) (see Figure L.2)

The dish is fitted with a filter paper (diameter 150 mm of 65 g/m²), previously moistened and drained by
placing on a dry filter paper, filled with paste, levelled and weighed prior to the test (as the mass of the
empty dish including the moist filter paper is known, the mass of the mixed paste and the corresponding
mass of the water used for mixing can be calculated in g).

These operations take place within 10 minutes of mixing. After 15 minutes (from when mixing started)
the apparatus is subjected to vacuum for 15 minutes; the dish is then weighed again after wiping off the
undersurface, and the loss of water (e) in g can be calculated by subtraction.

L.1.2.2 Density of fresh mortar

The mortar is prepared as detailed in L.1.2.0.

The apparent density is determined using a 1 litre cylindrical container, previously tarred (mass M0 in
g). The container is filled with paste and after compacting down, wiped off and weighed (mass M1 in g).
The density of the paste (in kg.m-3) is equal to M1 - M0.

The density of the paste is measured immediately after mixing.

L.1.3 Hardened base coat (without reinforcement)

The apparent density is determined on three specimens 160 mm x 40 mm x 40 mm (prism mould


compartments) by measuring mass and dimensions. The specimens are cured for at least 28 days at
(23 + 2) °C and (50 + 5) % relative humidity.

The precision for weighing is 0,1 g and for the dimensions 1 mm.

L.1.3.1 Products with a thickness greater than 5 mm

L.1.3.1.0 Preparation and storing of test samples

The mortar is prepared by mixing as described in L.1.2.0.

Test samples, conforming to the dimensions defined in the paragraphs below, are prepared in metal
moulds in two layers.

Each layer is compacted into position by dropping alternately each side of the mould from a height of 5
mm approximately ten times. The test samples are then levelled with a metal ruler.

The test samples are removed from the mould after 24 h.

They are then stored for at least 28 days at (23 + 2) °C and (50 + 5) % relative humidity.

L.1.3.1.1 Dynamic modulus of elasticity (Resonance frequency method)

The dynamic modulus of elasticity is determined on prismatic test samples measuring 25 mm x 25 mm


x 285 mm.

The test is carried out on the following:

- 3 samples prepared as described in L.1.3.1.0.

- 3 samples prepared with product taken at the time of the preparation of the rig described
(see 2.2.16).

The individual values of the apparent density (in kg/m 3) and the modulus (in MPa) of the 3 test samples
and the mean value of the results obtained are noted.

The principle of the measurement consists of measuring the basic resonance frequency of a test sample
under longitudinal vibration.

1 - Apparatus

The apparatus used for carrying out this measurement comprises:

a) A variable frequency oscillator with a frequency range of 20 kHz and a precision of 1 %.

b) An electromagnetic vibrator which may or may not be in mechanical contact with the test
sample; its mass shall be very light compared to that of the test sample.

c) A receiver, an electromechanical transducer and an amplifier; its mass shall be very light
compared to that of the test sample.
Draft EAD – European Assessment Document EAD 040759-00-0404, yyyy-mm adopted/final 88/97
EOTA file № 17-04-0759-04.04

The resonance frequencies of the vibrator and the receiver shall not fall between 0.5 kHz and
20 kHz.

d) An amplifier.

e) An apparatus indicating the vibration amplitudes (oscilloscope).

f) A very narrow support on which the test sample rests during the measurement, which shall
not hinder the longitudinal vibration of the test sample and which shall be in the nodal plane.

2 - Testing

The sample is centred on the support. The vibrator and the receiver are placed as shown in the figure
below:

Vibrator →  Receiver


Support

It is important that the ends of the test piece are free to vibrate in an axial direction. The vibration
generator and the receiver, if they are in contact with the test piece, should exert an equal very weak
stress on the two ends. In this case, it is recommended to weakly bond the mobile part of the vibrator to
the sample using a coupling product (mastic). The same applies for the receiver.

The variable frequency oscillator supplies the vibrator and the test piece vibrates longitudinally. The
vibrations are collected by the receiver and after amplification their amplitude is shown on a dial
(oscilloscope). For most frequency ranges, the vibration amplitude is quite small. But for certain
frequencies, the displacement becomes appreciable. The resonance conditions are created when
maximum amplitude is obtained on the indicating dial.

The frequency of the basic longitudinal resonance corresponds to the lowest frequency for which
maximum amplitude is obtained (for the higher harmonic frequencies a resonance is also produced).

Two measurements are carried out: the vibration is produced successively at the two ends of the test
piece. The mean value is recorded. If the difference between the two values is higher than 5 % the
vibrations are restarted.

The measurements of the mass and dimensions of the test piece are needed to calculate the modulus.
The precision for weighing is 1/1000 and for the dimensions 1/100.

3 - Expressing the results

As the basic longitudinal resonance frequency, the mass and the dimensions of the test piece are known
the dynamic modulus of elasticity is determined using the following formula:

Ed = 4L2 . F2 10-6

where:

Ed = longitudinal dynamic modulus of elasticity in N/mm2


L = length of test piece in meters
F = longitudinal resonance frequency in Hz
 = mass per unit volume in kg/m3.

L.1.3.1.2 Shrinkage test

The measurement is carried out on three samples of base coat measuring 20 mm x 40 mm x 160 mm
prepared and stored as described in L.1.3.1.0, by inserting measuring spindles in the front end (10 mm
x 40 mm) of the samples. Measurements are carried out at regular intervals. The value after 28 days is
Draft EAD – European Assessment Document EAD 040759-00-0404, yyyy-mm adopted/final 89/97
EOTA file № 17-04-0759-04.04

recorded. In addition, if there is doubt in the curve associated with stabilization, the test is continued and
the value after 56 days is recorded.

L.1.3.2 Products with a thickness up to 5 mm: static modulus of elasticity, tensile strength and
elongation at break

The tests are performed on test samples measuring 3 mm x 50 mm x 300 mm.

Moulds for the samples are made using appropriately positioned 3 mm thick strips of extruded
polystyrene adhered to expanded polystyrene boards.

After the base coat, without reinforcement has dried, test samples are cut from the polystyrene with hot
wire.

The test sample is subjected to a tensile test until it breaks using a suitable machine which records the
tensile stress and elongation. The distance between the jaws of the machine is 200 mm. The sample is

ANNEX M – TEST OF PLATE STIFFNESS OF PLASTIC ANCHORS FOR ETICS


M.1 General

The load resistance of the ETICS fixed by anchors is particularly linked to the mechanical properties
of the anchor plate and the insulation material. The minimum requirements to the properties of the
anchor plate are relevant for ETA for ETICS.
These properties are
• the load resistance and
• the plate stiffness.
of the anchor plate

This Annex covers pull-through tests to evaluate the pull-through resistance of the anchor plate and
the plate stiffness of plastic anchors for fixing of ETICS with rendering. The pull-through test shall be
carried out according to following clauses.

M.2 Details of method and criteria for assessment

The failure load of the anchor plate shall be determined from at least 5 tests using the product
type to be assessed only. During the tests the anchor plate shall rest on a solid support ring
with a clear inside diameter of 30 mm. A preload can be applied for determination of the stiffness
for curved anchor plates in a way, that the tension load is be transmitted at the inside edge of
the support ring. If the anchor plate is stiffened by ribs, recesses, which prevent a contact
between the ribs and the supporting ring and the load transmission is not effected by the ribs,
shall be designed in the steel ring.

A principle test setup is shown in Figure M.2.

(Clamping jaw is clamping the expansion element)

Figure M.2 Principle description of the test for determination of the plate stiffness

For plastic anchor plates, which change their mechanical properties under influence of humidity, the
tests shall be carried out using air-humid conditioned anchors but always in ambient temperature

EOTA file № 17-04-0759-04.04

(standard conditions: equilibrium water content at T = +23 °C and 50 % relative humidity). The tension
load is transmitted over the anchor shaft with a loading rate of 1 kN/min ± 20 %.

M.3 Assessing of method and criteria for assessment

M.3.1 Load resistance

The characteristic resistance has to be determined from the 5%-quantile of the ultimate loads for a
confidence level of 90 %. This value has to be stated in the ETA. The characteristic resistance shall at
least comply with the characteristic resistance in the ETICS according to this EAD. If the characteristic
resistance amounts at least 1.0 kN, the universal application mentioned above can be ensured. The
reduction of the resistance of the anchor plate caused by increased temperature is included in this value.

M.3.2 Plate stiffness

For getting a comparable dimension for the plate stiffness, the tangent stiffness (c) has to be determined
for every test. This tangent stiffness states the gradient of an idealised straight line between the points
su (displacement in mm) with the appropriate tension force Nu = 0 kN and so = 1 mm (displacement) with
the appropriate tension force No in the load-displacement-diagram (see Figure M.3.1).

The plate stiffness and the diameter of the anchor plate shall be stated in the ETA.

Tangents stiffness (in kN/mm):

No − Nu No
c = = (M.3.1)
so − su 1 mm − su

with su ≤ 0.3 So

The evaluated values should be rounded upward expediently to 1/10 kN and be stated related to 1 mm
deformation (e.g. 0.3 kN/mm / 0.4 kN/mm / 0.5 kN/mm / 0.6 kN/mm / 0.7 kN/mm).
For characterising the plate stiffness the mean value has to be stated in ETA. The coefficient of variation
shall not exceed 20 %.

ANNEX N – POINT THERMAL TRANSMITTANCE OF PLASTIC ANCHORS FOR


ETICS
N. 1 General

Anchor in ETICS penetrates thermal insulation layer, acts as thermal bridge and increases heat
loss in the sphere of influence of the anchor. Effect of anchor on thermal performance of ETICS is
determined by the point thermal transmittance  of the anchor. The value of the point thermal
transmittance  depends on the dimensions of cross section of anchor construction, material of
anchor (its thermal conductivity) and thermal conductivity and thickness of the insulating layer and
the substrate.

ETICS are produced in a large range of thicknesses (approx. between 50 mm and 450 mm). At present
time, the average thickness of the insulating layer is approx. 150 mm with a tendency to rise. The -
value can increase with a greater thickness of the insulating layer, the behaviour is not linear. Variants
of relation of point thermal transmittance  to thickness of the insulating layer are shown on Figure
N.1.

The point thermal transmittances  is to be listed separately for thicknesses of the insulating layer of the
ETICS "up to 150 mm" and "greater than 150 mm". This is appropriate in order not to require the most
unfavourable -value for the entire area of the insulating layer thickness as representative dimension.

To simplify the procedure of assessment, the -value can be determined in the most unfavourable
substrate (base material group), where the anchor may be used. Alternatively the -value can be
determined for each base material group separately. Manufacturer can select the procedure, if he
does not, procedure with specification of critical case is to be applied.

N. 2 Assessment of point thermal transmittance

The point thermal transmittance  results from equation:

𝑈𝑐 − 𝑈
 =
𝑛

where  is point thermal transmittance of an anchor [W/K]

Uc thermal transmittance of the wall with ETICS and anchor(s) [W/(m 2K)]

U thermal transmittance of the wall with ETICS, without anchor(s) [W/(m 2K)]

n number of anchors per m2 [1/m2]

For each insulating layer thickness and for each base material group (substrate) calculated with
the point thermal transmittances are to be determined according to N.3.1. The final value(s) of the
point thermal transmittance  is to be rounded to four decimal places upwards and given in the ETA.

The step "0 W/K" is given in the ETA, if the peak value of the point thermal transmittance of anchor  in
the considered range is smaller than 0,0005 W/K. In such case, the following note is to be recorded for
the step "0 W/K" in the ETA for relevant type of anchor: "The point thermal transmittance  of the anchor
is smaller than 0,0005 W/K and therefore its effect in calculation of thermal characteristic of the ETICS
can be neglected.”

Description of the nominal value of the point thermal transmittance

The nominal value of the point thermal transmittance  is to be given for each base material group
or for the most unfavourable base material group, in which the anchor may be used. The point
thermal transmittance  is to be given as a single value or tabulated depending on the base material
group. For examples for the description, See N.4.

Nominal values determined only for the most unfavourable base material group
The nominal values includes all base material groups, with which the anchor might be used, as
index (see N.3.1.2). The area of insulating layer thickness for which the nominal value is valid is
stated in brackets behind the " ". Indexing of the base material groups is optional when the nominal
value is determined from base material group A.

Nominal values determined for different base material groups


These values are to be stated in a table, which includes all base material groups, the anchor might
be used with, line by line and the areas of insulation thickness, for which the nominal value shall
be given, column by column.

N.2.1 Different nominal values for the areas of insulating layer thickness

The nominal value of the point thermal transmittance  will be determined for the significant areas
as follows:

(h ≤ 150) the major value of (hmin) and (150 mm)

(h > 150) the major value of (hmax) and (150 mm)

where h is insulating layer thickness of the ETICS [mm]

hmin minimum insulating layer thickness according to the manufacturer instruction


[mm]

hmax maximum insulating layer thickness according to the manufacturer instruction


[mm]

The nominal value of the point thermal transmittances has to be rounded upwards and shown in
the following steps in W/K: 0 / 0.001 / 0.002 / 0.003 / 0.004 / 0.006 / 0.008
Draft EAD – European Assessment Document EAD 040759-00-0404, yyyy-mm adopted/final 95/97
EOTA file № 17-04-0759-04.04

N.2.2 No distinction between areas of insulating layer thickness

If only one significant -value is given as nominal value, it results as peak value from all tests
according to N.3.2:

(hmin - hmax) peak value (i.e. maximum) for the range from h = hmin to h = hmax

The nominal value of the point thermal transmittances has to be rounded upwards and shown in
the following steps in W/K: 0 / 0.001 / 0.002 / 0.003 / 0.004 / 0.006 / 0.008

N.3 Details of the test method

N.3.1 Test sample and conditions

For determination of the point, thermal transmittance  the following reference construction is used
as basis:

Figure N.3.1 Drawing of the reference construction (not full-scale)

Thickness of thermal insulation layer h for testing is taken according to way selected by
manufacturer, as specified below. The anchor has to be arranged according to the installation
manual of the manufacturer in centre of test specimen in position as in real construction.

For the building component layers the characteristic values of used construction material according
to EN 12524 are to be used:

Thickness of insulating layer

The thickness of the insulating layer has influence on the point thermal transmittance. The nominal
value of the point thermal transmittance  is to be determined for the ranges of insulating layer
thickness h ≤ 150 mm and h > 150 mm. Based on manufacturer´s request, if the point thermal
transmittance  for three thicknesses of insulating layer is determined, thicknesses assessed are
as follows:

(hmin) = for the smallest thickness of the insulating layer hmin indicated by the manufacturer

(h150) = for the thickness of the insulating layer h = 150 mm

(hmax) = for the biggest thickness of the insulating layer hmax indicated by the manufacturer

If determined value (150 mm) is smaller than (hmin), test of (hmax) can be neglected, because it
is assumed that in any case (hmax) is smaller than or equal to (150 mm).

Anchor characteristics

The thermal conductivity of anchor material is to be taken according to EN 12524 or ISO 10456.

The dimensions of the anchor are to be determined by means of a test specimen or they are to be
taken from the manufacturer's technical documentation.

Boundary conditions

The heat transfer resistances for external and internal surface are taken from 6.8 and Table 7 of
EN ISO 6946 for the horizontal thermal conductivity by values Rse = 0.04 (m2K)/W and Rsi = 0.13
(m2K)/W.

The temperature difference between inside and outside surface of tested specimen is to be T =
35 K (e.g.: θse = -15 °C; θsi = 20 °C).

The edge surfaces of the test specimen are to be considered as adiabatic.

N.3.2 Measurement

The determination of the thermal transmittance U c is to be performed in accordance with EN 1946-1


and 1946-4. The measurement can be realised according to EN ISO 8990.

A reference test specimen without anchors with identical thickness of insulating layer is to be used for
each measured thickness. The thermal transmittance U of the undisturbed test specimen is to be
measured according to the same method as for the thermal transmittance Uc.

Note: When placing the anchor, the distance to the edge and between the anchors should not fall
below 300 mm.

Examples for the description of nominal values of the point thermal transmittance :
Example 1: Single values

An anchor might be used in the base material groups A and B for thicknesses of insulating layer
hmin = 50 mm up to hmax = 320 mm. Following nominal values have been determined by test:

(h ≤ 150 mm) = 0.002 W/K and (h > 150 mm) = 0.003 W/K
A listening as table is not necessary because the nominal values have been determined for one
base material group only. The description is given in single values.

Case 1: Distinction between areas of insulation thicknesses:


(h ≤ 150 mm) = 0.002 W/K; (h > 150 mm) = 0.003 W/K
Case 2: One -value for the whole area of insulation thicknesses:
(h = 50 – 320 mm) = 0.003 W/K
Indexing is not necessary because the nominal value was calculated with base material group A.

Example 2: Table or single values

An anchor might be used in the base material groups B, C and D for thicknesses of insulating layer
hmin = 50 mm up to hmax = 250 mm. Following nominal values have been determined by test:

B(h ≤ 150 mm) = 0.002 W/K and B(h > 150 mm) = 0.001 W/K
D(h ≤ 150 mm) = 0.001 W/K and D(h > 150 mm) = 0.001 W/K
Values for C have not been determined. The values from the next higher base material group B
apply for this group also.
Alternative A: Description as single values
One of the following description has to be stated for the anchor:

Case 1: B, C, D(h ≤ 150 mm) = 0.002 W/K; B, C, D (h > 150 mm) = 0.001 W/K
Case 2: B, C, D(50 - 250 mm) = 0.002 W/K
