DIN EN 14964:2007-01

This European Standard specifies the technical requirements for factory made flat or profiled sheets (e. g. wood-based, fibre cement or corrugated bituminous sheets) that are used as underlays in pitched roof constructions with discontinuously laid coverings (e. g. tiles, slates). This standard also establishes methods of inspection and testing as well as criteria for evaluation of conformity. This standard does not include: rigid underlays which have a stiffening function and asbestos containing products.
