ÖNORM EN 544

This document specifies the properties, performance and methods of test of the finished bitumen shingles prior to them being laid on the roof. It also includes rules for marking, labelling and provides a clause for assessment and verification of constancy of performance (AVCP). This document does not include design requirements, installation techniques and roof system performance. This document applies to bitumen shingles where the watertightness of the system is ensured by overlapping, by different adhesive systems or a combination of these, according to manufacturer’s installation instructions, intended to be laid as covering for pitched roofs and/or wall cladding. This document applies only to bitumen shingles with a mineral reinforcement, synthetic reinforcement or a mixture of the two. This document covers shingles with a minimum mass of bitumen of 1 300 g/m2 in case of monolayer shingles and 1 500g/m² in case of multilayer shingle. In case of multilayer shingles each layer need to have the same type of reinforcement and same type of coating.
