5 Testing
5.1 Sampling
Samples shall be taken in accordance with EN 13416.
5.2 Test methods
5.2.1 DetermInation of dimensions, straightness and mass per unit area
The length, width, straightness and mass per unit area of underlays shall be determined in accordance with EN 1648-1 and EN 1849-1 for bitumen sheets and in accordance with EN 1848-2 and EN 1849-2 for all other sheets.
5.2.2 DetermInation of reaction to fir.
Where required, the product shall be tested and classified in accordance with EN 13501-1:2007. Table 1. When tested according to EN ISO 11925.2. the products shall be tested under condibons of surface flame attack (surface exposure).
NOTE 1 It is Currentty considered that the Euroclasses Ciassification System at Classes 1) and above requires investigation to delemvne its appropriateness to the products covered by this document (the S8I test (EN 138232002) may be lnappropnate for products covered by the standard). Pending results of such an investigation and discussions In the Fire Regulators Group. products covered by this document are tested to EN ISO 11925-2.
If and a new fire test scenario and lest method are developed for the products, this document will be amended to refer to them.
The underlays. wf’iere no limitation in the application is requested, shall be tested free hanging (without substrate) only. The classification obtained shall be applied to all unsupported and supported end use applications.
NOTE 2 If the intended use of the undeday is solely lenuted to being supported art a specific substrate. e. g. wood, mineral wool, poiiJrethane, it should be tested in the end use appcalion ii accordance with EN 13238.
5.2.3 Determination of resistance to water penetration Class Ill
The resistance to water penetration Class ill shall be determined in accordance with EN 1928:2000. Method A, with the modifications that:
— the water column shall be 200 mm;
using water dyed with 005 % eosin (instead of a moisture indicating mixture or sugar and methylene blue):
— one layer of laboratory filter paper with a mass per unit area of 80 9/rn2:
— test perIod: 2 h (instead of 24 h):
— three test specimens are used.
5.2.4 Determination of resistance to water penetration Class Ni
The resistance to water penetration Class W2 shall be determined in accordance with EN 13111 using three
test specimens
5.2.5 Determination of water vapour transmission properties
5.2.5.1 Determination of water vapour transmission properties using EN 1931
The waler vapour transmission properties shall be determined in accordance with EN 1931 using five test
specimens.
5.2.5.2 Determination of water vapour transmissions properties using EN ISO 12572
The water vapour transmission properhes shall be determined in accordance with EN ISO 12572 using the set of conditions C and using five test specimens.
5.2.6 Determination of resistance to penetration of air
The product shaü be tested in acccrdance with EN 12114.
The test area .4, in m2, shall be 0,5 m2 .4 1,0 m2, the maxinum pressure difference shall be
= 100 Pa,
5.2.7 DetermInation of tensile properties
The tensile properties of foldable products shall be tested wi accordance with EN 12311-1 and the modifications indicated in Annex A. Unfoldable products shall be tested in accordance with EN 12311-1 without these modifications
5.2.8 Determination of resistance to tearing (nail shank)
The resistance to tearing of foldable products shall b€ tested in accordance with EN 12310-1 and the modifications indicated In Annex B. Unfoldabie products shall b€ tested in accordance with EN 12310-1 without these modifications.
5.2.9 Determination of dimensional stability
The dimensional stability shall be tested in accordance with EN 1107-1 for bitumen sheets and in accordance with EN 1107-2 for all other materials.
5.2.10 Determination of felexiblllty at low temperature (pliability)
The flexibility at low temperature shall be tested in accordance with EN 1109.
