This European Standard specifies two methods for the determination of the tensile properties of plastic and rubber sheets for roof waterproofing:
Method A based on EN ISO 1421, is the preferred method which should be used for all materials. If method A is not suited to the material, i. e. the material does not rupture, method B based on ISO 37 can then be used to determine tensile properties.
