4.3 For specific applications
4.3.1 General
If there is no requirement for a property described in 4.3 for a product in use, then the properly does not need
to be determined and declared by the manufacturer.
4.3.2 Dimensional stability und.r sp.cIfI.d temperatur. and humidity conditions
Dimensional stability under specified tempeature conditions shaM be determined in accordance with EN 1604. The test shaM be carried out for 481, exposure at (70 ± 2) C and (50±5) % relative humidity. The relative changes in length, and width, shall not exceed 0,5%. The relative changes in thickness. ird, shall not exceed 1%.
4.3.3 Compressive stress or compressive strength
Compressive stress at 10% deformation, o. or the compressive strength, , shall be determined in accordance with EN 826. No test result for either the compressive stress at 10% deformation, or the compressive strength, , whichever is the snialer. shall be less than the value given in Table 2, for the declared level.
5.3 Testing
5.3.1 General
Table 6 gives the dimensions of the test specimens, the mimum number of measurements required to get one test result, and any specific Conditions which are necessary.
5.3.2 Thermal resistance and thermal conductivity
Thermal resistance and thermal conductivity shall be determined In accordance with EN 12667 or EN 12939 for thick products and under the following conditions:
— at mean temperature of (10 ± 0,3) C;
— after conditioning according to step 1 of 5.2 (i.e. under dry condition):
— using the provisions given m Annex C for the determination of the thermal conductivity in the relation to moisture content.
NOTE Thermal resistance and thermal conductivity may also be measured at mean temperatures other than 10 C, providing that the accuracy of the relationship between temperature and thermal properties is we documented.
Thermal resistance and thermal conductivity shall be determined directly at measured thickness. In the event that this is not possible, they shall be determined by measurements on other thicknesses of the product provkhng that:
product is of similar chemical and physical characteristics and is produced on the same production line:
— and it can be demonstrated Wi accordance with EN 12939 that the thermal conductivity. A. does not vary more than 2 % over the range of thicknesses where the calculation is applied.
5.3.3 Tensile strength perpendicular to faces
For measurements of tensde strength perpendicular to faces, additional provisions to the test method and test procedures of EN 1607 shall be as follows.
— rigid plates, made of steel, having a thickness of at least 5 mm;
adhesion of the test specimen to the rigid plates with oxydised hot bitumen, such as type 85125, or 100/40, or 110/30 for example;
— cooling the test specimens, bonded to the metal plates, for a minimum of 6 h at (23±5) C. before testing.
5.3.4 Water absorption by total immersion
Short-term water absorption by total immersion shall be measured, using the following test procedure:
— use apparatus and relevant normative references as mentioned in EN 1609;
select a test specimen of nominal product thickness, induding facing or coating if any, with dimensions as given in Table 6;
— weigh the test specimen to the nearest 0.1 g to determine its initial mass
— place the test specimen in a water tank, and keep It totally immersed for (2 ± 0,02) Ii, so that its lop lace remains under at least 2 mm of water.
