BS EN 534:2006 pdf download.Corrugated bitumen sheets— Product specification and test methods.

5.3.5 Water absorption
When tested according to 7.3.5, the water absorption shall be less than 20% of the mass of the sheet.
The properties are measured without any covering of granules or fine flakes.
5.3.6 Slip resistance
Due to their rough surfaces, corrugated bitumen sheets are not slippery products.
5.3.7 Load bearing
Installation guidelines shall recommend not to permit walking between the purlins (load bearing capacity is not covered by this product standard).
5.4 Durability
5.4.1 Tearing strength after freezeithaw ageing
When tested according to 7,4,1, the tearing strength shall not be lower than the inital threshoio values (5.2.3).
5.4.2 Water Impermeability after fr.ezethaw ageing
When tested according to 7.4.2, no drop of water shal pass through the sheet after 48 h.
5.4.3 Thermal coefficient
When tested according to 7.4.3, the value of a shall be less than 100 x 101/K.
5.5 Fire performance
5.5.1 ReactIon to fir.
This characteristic shall be declared when subject to regulatory requirements and may be declared when not subject to such requirements. Where the manufacturer wishes to make a declaration of the reaction to fire performance of his corrugated bitumen sheets (e.g when they are subject to regulatory requirements), the sheets shall be tested and classified in accordance with 7.5.1.
5.5.2 External fire performance
This characteristic shall be declared when subject to regulatory requirements and may be declared when not subØct to such requirements. Where the manufacturer wishes to make a declaration of the external fire performance of his corrugated bitumen sheets (e.g. when they are subiect to regulatory requirements), the sheets shall be tested and classified in accordance with 7.5.2.
