1 SCOPE OF THE EAD

1.1 Description of the construction product

This EAD is established for the assessment of product: a thermal insulation and/or a sound absorbing
board based on expanded polystyrene and cement.

The thermal insulation and/or sound absorbing boards based on expanded polystyrene and cement
(“insulation boards”) are factory made products of homogenous mixture of the granulates of expanded
polystyrene (EPS) and Portland cement (according to EN 197-1) and do not contain any other natural or
artificial aggregate. The granulates of expanded polystyrene (EPS) are made only from new polystyrene
granulates. If recycled material is used, only material originally manufactured according to EN 13163 is
used and its content (in percentage % of mass of total EPS content) shall be defined by the manufacturer.

The product is not covered by a harmonised European standard (hEN).

Concerning product packaging, transport, storage, maintenance, replacement and repair it is the
responsibility of the manufacturer to undertake the appropriate measures and to advise his clients on the
transport, storage, maintenance, replacement and repair of the product as he considers necessary.

It is assumed that the product will be installed according to the manufacturer’s instructions or (in absence
of such instructions) according to the usual practice of the building professionals.

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

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

1.2.1 Intended use(s)

The insulation board is used for thermal protection and/or sound absorbing of building constructions as
follows:
– external thermal protection of walls (e.g. ETICS)
– thermal insulation layer of floors, ceilings and roofs
– sound absorbing.

The insulation board is used in structures only where it is protected from wetting, weathering and
moisture.

1.2.2 Working life/Durability

The assessment methods included or referred to in this EAD have been written based on the
manufacturer’s request to take into account a working life of the thermal insulation and/or a sound
absorbing insulation boards of based on expanded polystyrene and cement for the intended use of 50
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 shall be taken into
account. The real working life may be, in normal use conditions, considerably longer without major
degradation affecting the basic requirements for works1.

1 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.

©EOTA 2016
European Assessment Document - EAD 040065-00-1201 5/25

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.

ANNEX A GUIDANCE FOR TEST OF REACTION TO FIRE ON THERMAL

INSULATION AND/OR SOUND ABSORBING BOARDS BASED ON EXPANDED
POLYSTYRENE AND CEMENT

1. General
This test covers homogenous insulation material according to clause 1.1 of the EAD without any coating
or finishing on its surface.

2. Conditioning
All specimens shall be conditioned according to the provisions given in EN 13238 before testing.

3. Testing according to EN ISO 1182 and EN ISO 1716

These methods are needed to determine classes A1 and A2 according to Commission Delegated
Regulation (EU) 2016/364 (also EN 13501-1). If required the specimens shall be prepared and tested
according to the provisions given in the test standards EN ISO 1182 and EN ISO 1716. Each different
chemical composition has to be considered when testing. In case of products with the same composition
but different densities and different amounts of organic components in particular expanded polystyrene
the variation with the lowest density and the highest amount of polystyrene and additional organic
components shall be tested. If the product contains flame retardant the variation with the lowest amount
of the flame retardant shall be tested.

The test result is valid for that variation tested and all variation of the products:
- with the same chemical composition,
- with higher densities,
- of any thickness,
- with lower amounts of polystyrene and additional organic components and
- with higher amounts of the same type of flame retardant as the one which has been tested.

4. Testing according to EN 13823 (SBI)

This method is relevant for determining of the classes A2, B, C and D as well as for the additional
classifications s1, s2, s3, d0, d1 and d2 regarding smoke production and flaming droplets. Using this
approach the end use applications have to be taken into account. Two different types of substrates are
possible in end use – solid floor structures made of mineral material (e. g. concrete) and floor structures
made of beams with timber floorboards or wood based panels on the upper side. Hence a particle board
according to EN 13238 shall be used as substrate for testing representing both types of substrates in
practice. If other substrates are possible in the end use application other substrates according to EN
13238 exactly representing the substrate of the end use application can be used for testing. Since the
reaction to fire performance of the insulation material shall be evaluated, all test shall be conducted
without any covering (e.g. screeds) to the insulation material.

The following test configuration shall be used:

1. The samples (insulation + substrate) will be produced in the dimensions of the SBI test specimens.
2. Due to the kind of production – casting of the insulation material on site without joints - no joints shall
be considered when preparing the long wing of the SBI specimens.
3. Both the short and the long wing of each sample will be mounted together on the SBI trolley after
conditioning.
4. The sample shall be mounted in a distance of 80 mm to the backing board of the SBI apparatus. For
samples with a thickness greater than 120 mm the distance can be reduced to 40 mm. The cavity
behind the sample shall be non-ventilated. Samples with a thickness greater than 160mm shall be
mounted directly in front of the backing board of the SBI apparatus without any distance to the
backing board.
5. The samples shall be fixed on the substrate only mechanically by screws with a diameter of 6 mm
(see Figure 1 and 2).
6. The correct length of the screws shall be derived from Figure 3.
7. Before fixing the sample, pilot holes with a diameter of 4 mm shall be drilled into the substrate
according to Figure 1 and 2.

©EOTA 2016
European Assessment Document - EAD 040065-00-1201 20/25

Instead of fixing of the insulation on the substrate using screws the whole sample can be mounted in a
steel frame made of U-profiles covering the lateral edges and the top edge of the sample.
The following parameters of the insulation material shall be taken into account when conducting the SBI
tests:
- each different chemical composition,
- the greatest and lowest thickness,
- the lowest density,
- the highest amount of polystyrene and additional organic components and
- the lowest amount of flame retardant.

The test results are valid for the variation tested and any variations of the product
- with the same chemical composition,
- with higher densities,
- all thickness between those evaluated in the tests,
- with lower amounts of polystyrene and additional organic components and
- with higher amounts of the same type of flame retardant as the one which has been tested.

Test results on the standard particleboard substrate or on other standard substrates are valid for those
end use substrates for which the standard substrate is representative according to the rules given in EN
13238.

5. Testing according to EN ISO 11925-2

This method is relevant for determining the reaction to fire classes B, C, D and E of Commission
Delegated Regulation (EU) 2016/364 (also EN 13501-1). Due to the thickness of the insulation material
used in practice, the low energy level of the ignition source and the short time of flame exposure the
influence of the end use condition can be considered as negligible when testing the specimens. Hence
the insulation material shall be tested without any substrate behind. Testing of all specimens shall be
conducted with edge exposure according to clause 7.3.3.2 of the test standard.

The following parameters shall be taken into account when preparing the specimens:
- each different chemical composition,
- the greatest thickness (usually that means the greatest testable thickness of 60 mm),
- the lowest density,
- the highest amount of polystyrene and additional organic components, and
- the lowest amount of flame retardant

The test results are valid for the variation tested and any variant of the product:
- with the same chemical composition,
- with higher densities,
- with lower amounts of polystyrene and additional organic components,
- with higher amounts of the same type of flame retardant as the one which has been tested and
- of any thickness, if the maximum testable thickness of 60 mm was tested.

If a lower thickness than 60 mm was used for testing test results are valid for lower thickness.
