1 Scope
This European Standard specifies the requirements for factory made expanded polystyrene products, with or
without rigid or flexible facings or coatings, which are used for the thermal insulation of buildings. The products
are manufactured in the form of boards or rolls or other preformed ware (flat, tapered, tongue and grooves,
shiplap, profiled etc.).
Products covered by this standard are also used for sound insulation and in prefabricated thermal insulation
systems and composite panels; the performance of systems incorporating these products is not covered.
This standard describes product characteristics and includes procedures for testing, evaluation of conformity,
marking and labelling.
This standard does not specify the required class or level of a given property to be achieved by a product to
demonstrate fitness for purpose in a particular application. The classes and levels required for a given
application are to be found in regulations or non-conflicting standards.
Products with a declared thermal resistance lower than 0,25 m²⋅K/W or a declared thermal conductivity at 10
°C greater than 0,060 W/(m⋅K) are not covered by this standard.
This standard does not cover in-situ insulation products (covered by FprEN 16025-1 and -2), products
intended to be used for the insulation of building equipment and industrial installations (covered by EN 14309),
products intended to be used in civil engineering applications (covered by EN 14933) and products intended
to be used in beam and block systems in floors (covered by EN 15037-4).

with steps of 0,05 m²⋅K/W.
NOTE λ and R (design values) may be determined with reference to EN ISO 10456 [8].

4.2.2 Length and width
Length, l, and width, b, shall be determined in accordance with EN 822. No test result shall deviate from the
nominal values by more than the tolerances given in Table 1 for the declared class.
4.2.3 Thickness
Thickness, d, shall be determined in accordance with EN 823. No test result shall deviate from the nominal
thickness, d , by more than the tolerances given in Table 1 for the declared class.
N
This test shall not be performed when the tests described in 4.3.15 are used.
4.2.4 Squareness
Squareness, S, shall be determined in accordance with EN 824. The deviation from squareness on length and
width, S , shall not exceed the tolerances given in Table 1, for the declared class.
bi
4.2.5 Flatness
Flatness, P, shall be determined in accordance with EN 825. The maximum deviation from flatness, S , shall
max
not exceed the tolerances given in Table 1 for the declared class. This test is not applicable for EPS T
products.
