Introduction
This European Standard is intended for characterisation of plastic and rubber sheets as manufactured
or supplied before use. This test method relates exclusively to products or to their components where
appropriate, and not to waterproofing membrane systems composed of such products and installed in
the works.
This test is intended to be used in conjunction with European Standard "Definition and Characteristics"
for plastic and rubber sheets for roof waterproofing (EN 13956).
