The shape and the structure of corrugated bitumen sheets and the quality of the raw materials guarantee the properties. SIST EN 534:2006+A1:2010

EN 534:2006+A1:2010 (E) 6 Corrugated bitumen sheets may be spun-dyed. They may also be supplied with a coloured or colourless adhesive surface coating, which in turn may or may not have a covering of granules or fine flakes. Corrugated bitumen sheets may be manufactured as a mono-layer or a multi-layer product. Corrugated bitumen sheets are divided into category R and category S depending on their mechanical properties. For category R, all mechanical properties have to pass the threshold values of that category. For roofing applications, category R products are suitable for most climatic conditions, while Category S products may require special installation depending on the climatic conditions. For cladding applications, both categories are suitable. The manufacturer’s installation guide shall be consulted to ensure that the product is installed in the correct manner for its category. 5 Requirements 5.1 Geometrical properties 5.1.1 Length When tested according to 7.1.1, the tolerance on length L shall be + 1,0 %, – 0,2 %. 5.1.2 Width When tested according to 7.1.2, the tolerance on width w shall be ± 2 %. 5.1.3 Thickness When tested according to 7.1.3, the tolerance on thickness e shall be ± 10 %. The thickness of the corrugated bitumen sheets shall be measured including any surface relief (surface pattern) on the upper and lower sides (see Figure 4). NOTE Due to the fact that the relief of the surfaces may be very different (e.g. from one manufacturer to the other), the measurement of the thickness will give only some descriptive information and therefore cannot be directly compared between different products. 5.1.4 Height of corrugations When tested according to 7.1.4, the tolerance on the height of corrugations H shall be ± 6 %. For corrugated bitumen sheets with various corrugation heights, all the declared corrugation heights shall be measured. 5.1.5 Pitch of corrugations When tested according to 7.1.5, the tolerance on the pitch of corrugations p shall be ± 3 %. For corrugated bitumen sheets with various pitches and/or period of corrugation, all the declared pitches and/or periods shall be measured. SIST EN 534:2006+A1:2010

EN 534:2006+A1:2010 (E) 7 5.1.6 Squareness When tested according to 7.1.6, the squareness E shall be less than or equal to 4 mm/m. 5.2 Mechanical properties 5.2.1 Bending under downward load When tested according to 7.2.1, the minimum load for a deflection of 1/200 of a span of 620 mm shall be:  category R ≥ 1400 N/m2  category S > 700 N/m2 NOTE For calculation of maximum permissible load in manufacturers' installation guides, other methods may be used particularly in case of sheet shapes that do not allow the distributed downward load described in 7.2.1 to be applied. 5.2.2 Impact strength When tested according to 7.2.2, the falling height with a span of 620 mm shall be:  category R = 400 mm;  category S = 250 mm. This requirement is not relevant for external wall finishing products. 5.2.3 Tearing strength When tested according to 7.2.3, the tear threshold value shall be greater than:  category R = 200 N;  category S = 150 N. Where, in the case of a corrugated bitumen sheet with various corrugation heights, the manufacturer defines which corrugation has to be used for fixing, only this corrugation has to be tested. 5.3 Physical properties 5.3.1 Water impermeability When tested according to 7.3.1, no drop of water shall pass through the sheet after 48 h. 5.3.2 Proportion of bitumen

When tested according to 7.3.2, the bitumen content shall be equal to or greater than 40 %. The properties are measured without any covering of granules or fine flakes. 5.3.3 Mass When tested according to 7.3.3, the tolerance on the declared mass (expressed in kg/m2) shall be ± 10 %.

EN 534:2006+A1:2010 (E) 8 5.3.4 Homogeneity of the product When tested according to 7.3.4, there shall be no area larger than 1 cm2 without bitumen. 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 capacity on the roof"""" !Load bearing capacity depends on the method of support and fixing, which are not included in the scope of this product standard. NOTE The load level, the levels of safety and permissible deflection are defined in EUROCODES and/or national building regulations." 5.4 Durability 5.4.1 Tearing strength after freeze/thaw ageing When tested according to 7.4.1, the tearing strength shall not be lower than the initial threshold values (5.2.3). 5.4.2 Water impermeability after freeze/thaw ageing When tested according to 7.4.2, no drop of water shall pass through the sheet after 48 h. 5.4.3 Thermal coefficient When tested according to 7.4.3, the value of α shall be less than 100 x 10-6 1/K. 5.5 Fire performance 5.5.1 Reaction to fire 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 subject 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 subject to regulatory requirements), the sheets shall be tested and classified in accordance with 7.5.2.

NOTE Cutting of the sheet may be necessary to ensure that the measurement can be taken correctly. The measurement shall be performed with a maximum pressure of 2 N/cm2, which guarantees a stable measurement without compression of the surface.

The zero shall be obtained by measuring the thickness of the flat bar before inserting the sheet. The flat bar shall be placed on two adjacent corrugations of the same height. The height of corrugations shall be measured at 50 mm from each end of the sheet. Four measurements, evenly distributed over the width of the corrugated sheet, leaving out the first and last corrugations, shall be taken.
