 SECTION ONE

INTRODUCTION

1. PRELIMINARIES
1.1 Legal basis
This Guideline for European Technical Approvals has been established in full compliance
with the provisions of the Council Directive 89/106/EEC (CPD) and has been established
taking into account the following steps:
• Issuing of the final mandate by the EC: 16 April 1998
• Issuing of the final mandate by EFTA: 16 April 1998
• Adoption of the Guideline by EOTA: (Executive Commission) 13 October 1999
• Endorsement of the document by the EC: SCC opinion of 9-10 December 1999
EC letter of 11 August 2000
• Endorsement of the document by EFTA: idem

This document is published by the Member States in their official language or languages
according to Art. 11/3 of the CPD

No existing ETA-Guideline is superseded.

1.2 Status of the ETA-Guidelines

1.2.1 An ETA is one of the two types of technical specifications
in the sense of the CPD, which means that Member States shall presume the approved
products fit for their intended use, e.g. that they enable works in which they are employed
to satisfy the Essential Requirements during an economically reasonable working life,
provided that:
- the works are properly designed and built;
- the conformity of the products with the ETA has been properly attested.

1.2.2 An ETA-Guideline is a basis for ETAs,

that is a basis for technical assessment of the fitness for use of a product for an intended
use. *)

ETA-Guidelines express the common understanding of the Approval Bodies of the

provisions of the EC-Construction Products Directive 89/106 (CPD) and of the
Interpretative Documents to the CPD, with regard to the products and uses concerned,
established within the framework of a mandate given by the Commission after consulting
the EC-Standing Committee for Construction.

1.2.3 ETA-Guidelines are binding

for the issuing of ETAs of the products concerned for an intended use, when accepted by
the EC-Commission after consultation with the Standing Committee for Construction and
published by the Member States in their official language or languages.
*) An ETA-Guideline is not in itself a technical specification in the sense of the CPD.

ETAG 005-1
Page 7
 The applicability to, and the satisfaction of, the ETA-Guideline for a product and its intended
use have to be assessed in a case-by-case evaluation by an authorised Approval Body.

Satisfaction of the provisions of an ETA-Guideline (examinations, tests and evaluation

methods) leads to a presumption of fitness for use only through this case-by-case
evaluation.

Products outside of the scope of an ETA-Guideline may be considered, where appropriate,

through the approval procedure without guidelines according to Art. 9.2. of the CPD.

The requirements in ETA-Guidelines are set out in terms of objectives and of relevant
actions to be taken into account. ETA-Guidelines specify values and characteristics, the
conformity with which gives the presumption that the requirements set out are satisfied,
whenever the state of art permits. The ETA-Guidelines may indicate alternate possibilities
for the demonstration of the satisfaction of the requirements.

2. SCOPE
This ETA-Guideline Part 1: General specifies the terminology and definitions, classification,
categorisation, requirements, methods of verification, assessment procedures, product
characteristics, attestation of conformity and content of the ETA for liquid applied roof
waterproofing kits (LARWK).

It also gives guidance for the assessment of the application methods and design rules,
based on the present "State of the Art". Consequently it will be updated in case of justifiable
reasons.

This ETA-Guideline is applicable to in-situ applied liquid roof waterproofing kits which, as an
assembled system being part of the works, are supposed to meet the Essential
Requirements for a period of:
a - 5 years as indicated by the Applicant for ETA
b - 10 years;
c - 25 years as indicated by the Applicant for ETA

This ETA-Guideline is NOT applicable to LARWK(s) for use on roofs accessible to

vehicles.

This ETA-Guideline Part 1 - General shall be used in conjunction with one of the
Complementary Parts which amplifies the scope with respect to a particular family of
products.

Annex I, list of the Complementary Parts for the particular family of products.

Annex II, list of Common Definitions (and clarifications) and Common Abbreviations.

Annex III guidance on the preparation of free samples of the assembled system of a
LARWK to be used for specific tests and/or verification..

Part 1 of this Guideline shall be used in conjunction with one of the Complementary Parts which amplify
the requirements in the context of a particular family of products.

The assessment of fitness for use is made on the assumption that the LARWK is installed, used and
maintained in accordance with the specifications laid down by the Applicant, lodged with, accepted and
registered by the Approval Body.

4.1 ER1: Mechanical resistance and stability

Liquid applied roof waterproofing kits (LARWK), as an assembled system, make no
contribution towards enabling a construction works to meet the requirements of ER1
Mechanical resistance and stability.
There are therefore no requirements.

4.2 ER2: Safety in case of fire

The Essential Requirement laid down in the Council Directive 89/106/EEC is as follows:
The construction works must be designed and built in such a way that in the event of an
outbreak of fire:
- the load bearing capacity of the construction can be assumed for a specific period of
time
- the generation and spread of fire and smoke within the works are limited
- the spread of fire to neighbouring construction works is limited
- occupants can leave the works or be rescued by other means
- the safety of rescue teams is taken into consideration

The following aspects of performance are relevant to this Essential Requirement for Liquid
Applied Roof Waterproofing Kits:

4.2.1 External fire performance

The external fire performance of the roof of which the applied roof waterproofing kit form
part shall be in accordance with laws, regulations and administrative provisions applicable
to the roof of which the applied roof waterproofing kit form part in its intended end use
application. This performance shall be expressed in the form of a classification specified in
accordance with the relevant EC decision and the appropriate CEN classification standards.

4.2.2 Reaction to fire

The reaction to fire performance of the liquid applied roof waterproof kit as applied as an
assembled system shall be in accordance with laws, regulations and administrative
provisions applicable to the liquid applied roof waterproof kit as applied as an assembled
system in its intended end use application. This performance shall be expressed in the form
of a classification specified in accordance with the relevant EC decision and the appropriate
CEN classification standards.

4.2.3 Working Life, Durability

Compliance with the Essential Requirement throughout the working life requires that, during
the intended use, the assembled system remains undamaged and that the properties are
not subject to unacceptable changes due to external agencies in such a way as to affect the
reaction to fire and the external fire performance of the assembled system.

ETAG 005-1
Page 13
4.3 ER3: Hygiene, health and the environment
4.3.1 Indoor environment
In conjunction with the other elements of the roof construction, an assembled system of a
LARWK shall control the ingress of moisture from the outside into the building, in both liquid
and vapour form, to control the presence of damp in parts of the works or on surfaces within
the works.

4.3.2 Outdoor environment

4.3.2.1. Release of dangerous substances

The product/kit must be such that, when installed according to the appropriate provisions of
the Member States, it allows for the satisfaction of the ER3 of the CPD as expressed by the
national provisions of the Member States and in particular does not cause harmful emission
of toxic gases, dangerous particles or radiation to the indoor environment nor contamination
of the outdoor environment (air, soil or water).

4.3.3 Working Life, Durability

Compliance with the Essential Requirement throughout the working life requires that, during
the intended use, the assembled system remains undamaged and that the properties are
not subject to unacceptable changes due to external agencies. The assembled system shall
be resistant to the effects of:

i) wind loads;
ii) mechanical damage;
iii) movement;
iv) surface temperature extremes during use;
v) ageing media, including heat, UV radiation and water;
vi) plant roots

4.4 ER4: Safety in use

4.4.1 Resistance to wind load
The assembled system of a LARWK shall have sufficient mechanical resistance and
stability against wind loads to avoid detachement of parts of the work that, by falling down,
might form the risk of injury or death of users in or around the work.

The aspects of performance that can influence the meeting of the Essential Requirements
are dealt with under ER3 - Hygiene, health and the environment. (see 4.3.1 Indoor
environment and 4.3.3 Working life / durability)

4.4.2 Slipperiness
The surface of the LAWRK shall not be slippery due to either the inherent surface
conditions or the presence of water or grease on the surface so that it will influence the
probability of falling after slipping and thereby causing a risk for the occupants/users.

4.4.3 Working life, durability

Compliance with the Essential Requirement throughout the working life requires that, during
the intended use, the assembled system remains attached. This aspect is dealt with under
ER3 – Hygiene, health and the environment (see 4.3.3 Working life / durability)

ETAG 005-1
Page 14
4.5 ER5: Protection against noise
The assembled system of a LARWK makes no contribution towards enabling a construction
works to meet the requirements of ER5 - Protection against noise.
There are therefore no requirements.

4.6 ER6: Energy economy and heat retention

The assembled system of a LARWK makes no direct contribution towards enabling a
construction works to meet the requirements of ER6 - Energy economy and heat retention.
There are therefore no requirements.

The aspects of performance related to moisture ingress that can influence the meeting of
this Essential Requirement are dealt with under ER3 - Hygiene, health and the environment.
(See 4.3.1 Indoor environment.)

4.7 Related aspects of serviceability

4.7.0 General
Account shall be taken of all aspects of use, specification and expected working life that will
affect the assessment of fitness for use at the local level. These will include climatic zone in
which the assembled system of a LARWK will be used (influencing surface temperatures,
levels of UV radiation, durability etc.), accessibility and slope of the roof etc. This will
necessitate the use of categorisations for the systems.

4.7.1 Effects of application conditions

Where the Applicant declares a range of permitted weather conditions or permits variations
in proportions and/or the nature of constituent parts, it must be verified that the LARWK and
its assembled system satisfies the performance requirements over the whole range of
conditions.

4.7.2 Classification according to safety in case of fire

4.7.2.0 General
The Applicant shall classify each of the kits according to clause 4.7.2.2.
Classification will facilitate the assessment of fitness for use of the assembled system and
the satisfaction of the Essential Requirement where differences in performance are
expected due to reaction to fire. The declared classifications shall be taken into account in
the verification of performance against the Essential Requirement ER2.

4.7.2.1 Classification according to external fire performance.

Classification of the LARWK with respect to external fire performance is undertaken in
accordance with prEN 13501-5.
Commission Decision 2000/553/EC shall be taken into account.

4.7.2.2 Classification according to reaction to fire

Classification of the LARWK with respect to reaction to fire is undertaken in accordance
with:
EN 13501-1: Reaction to fire - Classification

The following range of Euroclasses is used:

ETAG 005-1
Page 15
 A1, A2, B, C, D, E, F

4.7.3 Categorisation according to use

4.7.3.0 General
The Applicant shall categorise each of his kits according to the categories given in 4.7.3.1
to 4.7.3.5. Categorisation will facilitate the assessment of fitness for use of the assembled
systems and of the satisfaction of the Essential Requirements for different expected
working lives or where differences in performance are expected due to the intended use.
The declared categorisation shall be taken into account in the verification of performance
against the Essential Requirements.

4.7.3.1 Categorisation according to working life

This Guideline is written on the assumption that the estimated working life of assembled
systems for the intended use is 10 years. In special circumstances, where indicated by the
Applicant, this may be modified to 5 or 25 years.

An estimated working life of assembled systems of 5 years shall only be assumed in the
case of LARWKs intended for use as a repair, renovation or maintenance medium only, or
for use solely in construction works which have a limited intended life.

An estimated working life of 25 years shall only be assumed in the case where the
Applicant can offer, for examination by the Approval Body, examples of satisfactory use of
that assembled system for a period of at least 5 years in a relevant situation and/or climate.
All product specifications and assessment methods shall take account of this expected
working life of 25 years.
The categories according to working life are given in Table 2.

Table 2 - Categorisation according to working life

Category Category Category

Expected working life (years) 5 10 25

The indication given on the working life of assembled system(s) cannot be interpreted as a
guarantee by the Applicant (or the Approval Body) but is regarded only as a means of
choosing the appropriate products in relation to the expected economically reasonable
working life of the works (ID par. 5.2.2).

4.7.3.2 Categorisation according to climatic zone of use

The assembled system, including its support and protection (if any) shall be resistant to the
solar exposure effects (solar energy, temperature, etc) occurring during its expected
working life which will depend on the geographical location of use. Two categories of
climatic zone have been established (Moderate and Severe) and the limiting values for
mean annual radiant exposure and the mean air temperature during the warmest month
are defined in Table 3.

year

Note 1: The annual radiant exposure is the total amount of solar energy received by
horizontal global surface within a defined geographical region, calculated as a mean
measured value over a period of five years. The average temperature of the warmest
month is the calculated mean value over a period of five years for the average measured
maximum air temperature of that month.

Note 2: The "isoline 5" (see map of TR-010.C - mean UV radiant exposure) can be used
as an indicative dividing line between "moderate" and "severe" climatic zones of use,
related to temperatures.

For a Category M kit to be suitable for use in a particular location both the parameters at
that location (derived from national meteorological statistics) shall comply with the limiting
values given in Table 3. If one of the parameters exceeds the limiting values for Category M
then only kits of Category S may be used.

The appropriate climatic zone category required may be declared by Member States [see
CPD
art. 3(2)]. Kits assessed as fit for use only in the Moderate zone may not be used in those
climates categorised as Severe for the same expected working life.

4.7.3.3 Categorisation of user loads

The assembled systems, including their support and protection (if any), shall be capable of
withstanding mechanical damage due to the user loads likely to occur during their working
life. The risk of mechanical damage will depend on the accessibility of the roof and the
frequency of the traffic envisaged. The appropriate categories of user loads and examples
of the related accessibility are given in Table 4.

Table 4 - Categorisation according to user loads

Category User load Examples of accessibility

4.7.3.5 Categorisation according to surface temperature

The assembled system, including its support and protection (if any) shall be resistant to the
maximum and minimum surface temperatures occurring during its expected working life
which will depend on the geographical location of use (see Table 3) and the levels of
protection. Tables 6(a) and 6(b) define the appropriate categories.

5. METHODS OF VERIFICATION

5.0 General
The methods of verification given in this section shall be applied, where appropriate, to the
kits proposed by the Applicant. Where possible the Approval Body shall select the kits and
levels to be tested so that extrapolation and interpolation are possible, thereby reducing the
number of necessary tests. In general a satisfactory performance at a severe level will
assure acceptance at a less severe level.

It is the responsibility of the Approval Body to identify the most unfavourable conditions e.g.
thickness of samples etc..

Reference shall also be made to the appropriate Complementary Part relevant to the family
of products which may identify tests omitted or include additional requirements specific to
that family of products.

The verification of performances shall take into account the declared classification and
categorisation of the kit(s) and may also include inspection of existing works.

The relationship between the requirements as defined in clause 4, the product performance
and the methods of verification listed below, are summarised in Table 7.

Identification
(1)Depending upon the nature and type of products, the text of the ETAG shall provide
indications as to how products shall be identified for approval and other purposes.
However what is written shall be flexible because of differences in manufacturing
techniques, the possible range of sizes of factories/manufacturing facilities, size of batches
and amount of product produced in a given time.

(2) Example techniques and procedures to be considered

either individually or in combination (not exhaustive)

• Fingerprinting (infrared, gas chromatography, ……………..)

• Formulation (chemical constitution, recipes, composition of raw materials, amounts,
components specified by characteristics, compliance with other specifications eg. ENs or
by weight, volume, percentage……………..)
• Manufacturing process parameters (temperature, pressure, time … product/production
codes)
• Testing of physical characteristics - data (geometry, density, mechanical
strength…………)
• Calculations, detailing, drawings

(3) Whichever method(s) is/are used it is necessary to recognise practical tolerances in

relation to results/data collected.

(4) It is however also essential that these techniques/methods shall be introduced only as
far as they have or could have an influence on the fulfilment of the Essential
Requirements, including aspects of durability.

5.2 ER 2: Safety in case of fire
5.2.1 External fire performance
5.2.1.1 The Liquid Applied Roof Waterproofing Kit as an assembled system shall be tested using
the method relevant for the corresponding external performance roof class, in order to be
classified according to pr EN 13501-5[1].

5.2.1.2 External fire performance cannot be claimed for individual products alone, since it is a
characteristic of a complete roof system. When the product is not a kit, the manufacturer
will need to fully define the assembled system of which the product will form part in order to
make any external fire performance claim.

5.2.1.3 The liquid applied roof waterproofing kit as an assembled system, may form as part of a
roof, may be considered “deemed to satisfy” all the provisions for external fire performance
of all National regulations of the Member States without the need for testing. This on the
basis that is included within the definitions given Commission Decision 2000/553/EC and
provided that any national provisions on the design and executions of works are fulfilled.

5.2.1.4 Where more than one assembled system is possible for an individual Liquid Applied Roof
Waterproofing Kit a minimum of one ‘typical’ roof system shall be tested in accordance with
ENV 1187:2002, except where the assembled system can be classified without further
testing (CWFT) [2].

5.2.1.5 All other possible assembled systems shall be Classified as ‘No Performance Determined’.

[1]
This does not prelude the possibility of other assembled systems being tested, at the
request of the manufacturer.
[2]
Where assembled systems are protected by a durable protection layer, the external fire
performance can be controlled by the nature of this protection layer. Therefore verification
of the external fire performance may be omitted, provided the effect of the protection layer
is assessed and/or stipulated by Commission Decision (2000/553/EC).

5.2.2 Reaction to fire

The liquid applied roof waterproof kit as an assembled system shall be tested, using the
test method(s) relevant for the corresponding reaction to fire class, in order to be classified
according to EN 13501-1:2002.

Details are given in Annex IV, Reaction to Fire – Test Procedures

5.3 ER3: Hygiene, health and the environment

5.3.1 Indoor environment
5.3.1.1 Resistance to water vapour
To establish the resistance to the passage of water vapour through the assembled system,
the water vapour permeability of the assembled system shall be determined in accordance
with EN 1931, using a free sample according to Annex III.4. The value shall be declared by
the Applicant and verified by the Approval Body. From this value the water vapour
resistance shall be calculated for use in the design of the roof.

5.3.1.2 Watertightness
The watertightness of the assembled system shall be determined by testing in accordance
with the test method given in EOTA technical report TR 003.

5.3.2. Release of dangerous substances

5.3.2.1. – Presence of dangerous substances in the product

The applicant shall submit a written declaration stating whether or not the product/kit
ETAG 005-1
Page 23
 contains dangerous substances according to European and national regulations, when and
where relevant in the Member States of destination, and shall list these substances.

5.3.2.2 – Compliance with the applicable regulations

If the product/kit contains dangerous substances as declared above, the ETA will provide
the method(s) which has been used for demonstrating compliance with the applicable
regulations in the Member States of destination, according to the dated EU data-base
(method(s) of content or release, as appropriate).

5.3.2.3 – Application of the precautionary principle

An EOTA member has the possibility to provide to the other members, through the
Secretary General, warning about substances which, according to Health authorities of its
country, are considered to be dangerous under sound scientific evidence, but are not yet
regulated. Complete references about this evidence will be provided.
This information once agreed upon, will be kept in an EOTA data base, and will be
transferred to the Commission services.

The information contained in this EOTA data base will also be communicated to any ETA
applicant. On the basis of this information, a protocol of assessment of the product,
regarding this substance, could be established on request of a manufacturer with the
participation of the Approval Body which raised the issue.

5.3.3 Working Life, Durability

5.3.3.0 General
i) Previous use
For kits categorised W3 (25 years) the Approval Body shall take into account, by
examination where appropriate, existing examples of use of the assembled system.
Such examples of the assembled system shall be:
a) in the same, or more severe categorisation as that required for the kit to be assessed
and
b) as old as possible, with a minimum of 5 years.

Where such examples of previous use are not available, it may be possible to utilise
existing knowledge of the performance on sites of assembled systems from the same
family of products, meeting the above conditions. The Approval Body shall satisfy itself that
such indirect evidence of previous use is applicable to the kit under assessment.

ii) Durability assessment

The procedures given in sections 5.3.3.1 to 5.3.3.6 are based on performance tests.
To obtain a more complete assessment of durability, changes in material characteristics
after exposure to ageing media shall be examined. Ageing media used shall be as
described in 5.3.3.5 with the possibility of performing tests on intermediate time periods.
The methods of verification for the relevant material characteristics are given in the
Complementary Parts.

The nature of the substrate may influence the durability of the assembled system.
Therefore the compatibility of the assembled system with the substrate shall be assessed.
This may be done by comparative testing before and after ageing by water or heat.

5.3.3.1 Resistance to wind loads

To continue to comply with the Essential Requirements the assembled system shall resist

ETAG 005-1
Page 24
 the effects of wind loads.

i) If the assembled system is loose laid and ballasted the resistance to wind loads is provided
by the mass of the ballast used. Verification of performance shall be based on calculations
of the mass of ballast and the weight of the system.
Note: Information in that respect can be obtained from national regulations or from
EN 1990 together with ENV 1991-2-4.

ii) The resistance to wind loads of partially or fully bonded assembled systems shall be verified
by measuring the delamination strength at 23°C in accordance with the test method given in
EOTA technical report TR-004 for all proposed substrates.

iii) In the case of a assembled system incorporating a partially bonded supporting layer, a wind
uplift test in accordance with the method given in EOTA technical report TR-005 shall be
performed. This test shall be performed on the substrate giving the lowest delamination
strength at 23°C {see (ii) above}.

iv) Verification of performances of mechanically fastened supporting layer, including the

durability of the fasteners, will be covered by guideline 006 - MEFAWAME (Systems of
Mechanically Fastened Flexible Roof Waterproofing Membranes).

The resistance to mechanical damage shall be verified by subjecting the assembled system
to dynamic indentation and to static indentation.

5.3.3.2.1 Resistance to dynamic indentation

The resistance to dynamic indentation at 23°C shall be determined in accordance with the
test method given in EOTA technical report TR-006, using the indentor size appropriate to
the level of performance required and defined by the relevant user load category (see
Table 4). The relationship between the user load category and the levels of resistance to
dynamic indentation is given in Table 8.

These tests shall be performed on the most and least compressible of the substrates
specified by the Applicant for the kit in question.

5.3.3.2.2 Resistance to static indentation

The resistance to static indentation at 23°C shall be determined in accordance with the test
method given in EOTA technical report TR-007, using the load appropriate to the level of
performance required and defined by the relevant user load category (see Table 4). The
relationship between the user load category and the levels of resistance to static
indentation is given in Table 8.

These tests shall be performed on the most and least compressible of the substrates
specified by the Applicant for the kit in question.

 maximum surface temperature (see Table 6(b)) and the level of resistance (see Table 8),
defined by the categorisation of the kit.

iii) The effects of high temperatures on the stability of assembled systems from kits categorised
S3 and S4 only, shall be determined by performing the resistance to sliding test in accordance
with the method given in EOTA technical report TR-009 at the appropriate maximum surface
temperature defined by the categorisation of the kit (see Table 6(b)) and at the maximum
slope as defined by the categorisation of the kit according to roof slope (see Table 5).

This test is not required for assembled systems from kits categorised according to slope as S1
or S2. However for all kits used on vertical or near vertical parts of details, this test shall be
performed at a slope of 90°.

iv) Where an assembled system contains a supporting layer which is not fully bonded, the effects
of high temperatures are governed by the dimensional stability of that supporting layer.
Measurement of the dimensional stability of the supporting layer shall be part of the
identification of components, elaborated in the relevant Complementary Part.

5.3.3.5 Resistance to ageing media

5.3.3.5.1 Resistance to heat ageing

6. ASSESSING AND JUDGING THE FITNESS OF PRODUCTS FOR
INTENDED USE

6.0 General
Assessment of the performance of a LARWK in the context of the assembled system,
satisfying the Essential Requirements comprises:

i) verification of the identity of the product and/or its components and of the conformity with the
registration in the Manufacturer's Technical Dossier;

ii) the possible effects of the tolerances declared by the Applicant in 6.0 (i) above;

iii) verification as elaborated in clause 5 of the aspects of performance mentioned in clause 6, in

conjunction with any specific performances elaborated in the relevant Complementary Part;

iv) judging the results of these verifications in relation to the requirements given in this
clause 6 and the specific requirements, if any, given in the relevant Complementary Part:

v) retesting, if necessary, and/or re-assessing the results, in the event of a LARWK not meeting
the levels of performance required, and therefore being modified, re-classified or re-
categorised by the Applicant.

To enable the Approval Body to assess and judge the fitness for use of the LARWK, the
Applicant for ETA shall submit the necessary information to the Approval Body, by using the
Composition Information Form as shown in Table 14 of this document.

Each product, where relevant, shall be subdivided into different kits, related to methods of
application, components utilised, suitable substrates, etc.. The Applicant shall define the
relevant characteristics with tolerances, if applicable, of each kit offered for assessment.

Each kit shall be identifiable.

Judging the results as satisfactory justifies the assessment of the liquid applied roof

(see Guidance Paper “B” – document CONSTRUCT 95/135 Rev. 1).

8.2.1.2 Testing of samples taken at the factory (A/C-system 1)

Both large and small companies produce these products and there is a wide variation in the
materials used. Therefore a precise test plan can only be set up on a case-by-case basis.

In general it is not necessary to conduct tests on complete kits. Indirect methods will normally
be sufficient, eg control of raw materials, manufacturing processes and properties of
components.

8.2.1.3 Declaration of Conformity (A/C-systems 3 and 4)

When all the criteria of the Conformity Attestation are satisfied the manufacturer shall make a
Declaration of Conformity.

8.2.2 Tasks for the manufacturer or the Approved Body

8.2.2.1 Initial type testing
Approval tests will have been conducted by the Approval Body or under its responsibility (which
may include a proportion conducted by an indicated laboratory or by the manufacturer,
witnessed by the Approval Body) in accordance with chapter 5 of this ETA-Guideline.

ETAG 005-1
Page 43
 The Approval Body will have assessed the results of these tests in accordance with chapter 6
of this ETA-Guideline, as part of the ETA issuing procedure.

tion report).

K. Maintenance and repair Recommended procedures, frequencies,

means and specific maintenance of
surface protective finish layers, if any.

8.3.5 Test plan

The manufacturer and the Approval Body issuing the ETA shall agree an FPC test plan.

An agreed FPC test plan is necessary, as current standards relating to quality management
systems (Guidance Paper “B”, EN ISO 9001 / 9002, etc) do not ensure that the product
specification remains unchanged and they cannot address the technical validity of the type or
frequency of checks / tests.

The validity of the type and the frequency of checks / tests, conducted during production of the
components (kit) and, if applicable, on its “assembled system”, shall be considered.
This will include the checks conducted during manufacture on properties that cannot be
inspected at a later stage.
These will normally comprise:
- material properties
- compatibility of components

Where materials / components are not manufactured and tested by the supplier in accordance
with agreed methods, then, where appropriate, they must be subject to suitable checks / tests
by the manufacturer before acceptance.

 Details of the test plan shall be included in the Manufacturer's Technical Dossier.

8.3.6 Prescribed test plan (only A/C-System 1)

The manufacturer and the Approval Body, issuing the ETA, shall agree a prescribed test plan.

The characteristic to be addressed as described in the mandate is the Reaction to fire. This
will be controlled at least twice per year by analysis / measurement of the relevant
characteristics for the “assembled system” of the kit.

8.3.7 Modification of the MTD

If, subsequent to the issue of an ETA, the manufacturer wishes to modify the contents of the
MTD the proposed changes shall be submitted to the Approval Body (A/C-systems 3 and 4), or
to the Approved Body (A/C-system 1) who shall consult with the Approval Body, if necessary,
before implementation.

The proposed changes and their effects on the contents of the ETA shall be assessed by the
Approval Body. Additional tests or justifications may be required before approval is granted.
Significant changes may lead to the need to amend and re-issue the ETA.

Acceptable changes shall be recorded and registered by the Approval Body in an amended
MTD.

8.4 CE - marking and information

The ETA shall indicate the information to accompany the CE-marking, the placement of CE-
marking and the accompanying information (eg on the kit and/or components, an attached label,

According to the CE Guidace Paper “D” on CE-marking, the required information to accompany
the symbol “CE” is:
- identification number of the notified body (A/C-System 1)
- name / address or identifying mark of the manufacturer of the kit (LARWK)
- “class / type …..” indication as to clarify the intended use(s)
- last two digits of the year in which the marking was affixed
- number of the EC Certificate of Conformity (A/C-System 1)
- number of the ETA
- dangerous substances (see clause 5.3.2 of this ETAG)
- class of external fire performance
- class of reaction to fire

The CE marking should be accompanied by the information as given in the ETAG-format

document, taking into account that:
- If the ETA provides all the information regarding the performance characteristics and the
appropriate conditions for their achievement (e.g. details of the relevant end use
applications covered by the mounting and fixing arrangements provided for the purpose of
test), then reference to the ETA is sufficient.
- If the ETA covers more than one type of product, and the type designation provides all the
information regarding the performance characteristics and the appropriate conditions for

ETAG 005-1
Page 47
 their achievement (e.g. details of the relevant end use applications covered by the mounting
and fixing arrangements provided for the purpose of test), then reference to the ETA and the
relevant type is sufficient.
- Only when the above two options do not provide all the necessary information regarding the
mandated performance characteristics (table 4.1), then additional information regarding the
performance characteristics and the appropriate conditions for their achievement (e.g.
details of the relevant end use applications covered by the mounting and fixing
arrangements provided for the purpose of test), needs to accompany the CE Marking.
Reference to accompanying information should be given in the ETA.

THE ETA CONTENT

9. THE ETA CONTENT

9.1 The ETA content shall be in accordance with the Commission Decision 97/571/EC, dated
22 July 1997.

In section II.2 "characteristics of products and methods of verification" the ETA shall include
the following note::
In addition to the specific clauses relating to dangerous substances contained in this
European Technical Approval, there may be other requirements applicable to the products
falling within its scope (e.g. transposed European legislation and national laws, regulations
and administrative provisions). In order to meet the provisions of the EU Construction
Products Directive, these requirements need also to be complied with, when and where they
apply.

The ETA is issued for the product/kit on the basis of agreed data/information, deposited with
{the Approval Body name}, which identifies the product/kit that has been assessed and
judged. Changes to the product/production process/kit, which could result in this deposited
data/information being incorrect, should be notified to the {the Approval Body name} before
the changes are introduced. The {Approval body name} will decide whether or not such
changes affect the ETA and consequently the validity of the CE marking on the basis of the
ETA and if so whether further assessment/alterations to the ETA, shall be necessary.

9.2 The ETA shall contain information and/or references allowing for, where there is a need eg.
attestation of Conformity [see Chapter 8 clause 8.2.3.3 certification, evaluation of conformity
Systems 1 & 2], market surveillance, complaints or accidents [all Systems of A/C]), to
determine that the products on the market, or intended to be put on the market are in
compliance with the approved product as described in the ETA.

When such information/references are of a confidential nature it/they shall exist on the ETA
file managed by the Approval body and as necessary on the relevant file of any notified body
involved.

This information/references shall also be of assistance in any renewal of the ETA.

The type, scale, range of information will be based on the identification clauses in Chapter 5
of the ETAG.

III PREPARATION OF FREE SAMPLES

III.1 SCOPE
This Annex gives guidance on the procedure for the preparation of free samples of (an)
assembled system(s) of roof waterproofing kits (LARWKS).

III.2 INTRODUCTION
To perform specific tests and/or verifications (eg. the effects of ageing media on different
characteristics of liquid applied waterproofing membranes) it is necessary to prepare free film
samples of systems.

The method of free film sample preparation may differ with the system under examination and
the advice of the manufacturer should be sought on the most appropriate method to be used
with the materials.

III.3 APPARATUS
III.3.1 Base: a rigid support (eg of plywood, glass, plastic coated chipboard or MDF etc.) of sufficient
size to provide an even and stable substrate on which to prepare the sample(s)

III.3.2 Release agent: to avoid adhesion to the base and to allow subsequent removal of the sample.
Examples of release agents known to work are siliconised paper, spray furniture polish, spray
silicone release agent, micro-crystalline parafin wax, etc.

III.3.3 Thickness control: a means of ensuring a constant and controllable thickness of the free film.
Examples: wet film gauges, film spreaders, film casters, bar coaters, steel frames, etc.

III.3.4 Spirit level: to allow the base plate to be adjusted to a horizontal position.

III.4 FREE SAMPLE

III.4.1 Composition
The free sample is the roof waterproofing kit (LARWK), applied in accordance with the
manufacturer’s instructions to the appropriate ratio of constituent parts, or to the specified
composition by the Approval Body.

III.4.2 Number and size of free samples

The number and size of free samples will be declared by the Approval Body, dependent on the
relevant method of verification.

ETAG 005-1
Page 55
 Annex III

III.5 PROCEDURE
The base shall be placed on a firm support ensuring that it is horizontal.

The release agent shall be applied and, where necessary, allowed to dry. Where sheet release
agents are used, these shall be firmly fixed to the base without creases or wrinkles.

Apply the roof waterproofing kit (LARWK) in the appropriate number of coats, including
reinforcement, where appropriate, in accordance with the manufacturer’s instructions (by
spraying, spreading or brushing) to the prepared base. For two-coat brush-applied roof
waterproofing kits the manufacturer’s instructions for the direction of brushing shall be
followed. The mean thickness of the applied membrane shall be controlled in the appropriate
manner.

The sample shall be allowed to fully cure before removal, without straining, from the base. Any
area of free film falling outside the manufacturer’s thickness specification shall be rejected.

ETAG 005-1

 Annex IV
Reaction to fire – test procedures

The test methods depend on the classification which the product shall meet.
Tests according to EN ISO 11925-2 shall be carried out on substrates according to EN 13238.
When the liquid applied roof waterproofing kit is intended to be used in combination with other
substrates, it shall be tested in end-use practice. Liquid applied waterproofing kit shall be tested in its
highest intended thickness. The result is valid for lower thickness.
Tests according EN 13823 shall be carried out on substrates according to EN 13238. If the liquid
applied waterproofing kit is intended to be used in combination with other substrates it shall be tested
as in end-use practice. The liquid applied roof water proofing kit shall be tested in its highest and
lowest thickness intended to be used. The test specimen shall be installed on the sample carrier
according to figure 1.
As a result the tests for the classification to Euroclasses B, C, D and E according to EN 13501-1 refer
to the specified substrates and their characteristics. This may cause different Euroclasses for the liquid
applied roof waterproofing as an assembled system for different substrates.
