scope:

Specifies a test method for determining the resistance to peeling of a joint between two adjacent sheets of the same bitumen-bases roofing sheets. Is to be used for testing the joints in mechanically fastened or ballasted single layer bitumen roofing. It is not designed for testing fully bonded or multilayer built up roofing. The peeling characteristics of a joint between two widths of bitumen-based sheets vary considerably depending on the method of jointing (flame or heat welding, hot adhesive or bitumen, cold adhesive) etc. the size of the overlap and the workmanship. This method is designed to be used for charcterisation tests and/or quality control of both the system and the installer.
