DIN EN 12317-1:1999 Flexible sheets for waterproofing - Part 1: Bitumen sheets for roof waterproofing; determination of shear resistance of joints; German version EN 12317-1:1999
The document specifies a test method for determining the resistance to shearing of a joint between two adjacent sheets of the same bitumen-based roofing sheets. It 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 shearing 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 characterization tests and/or quality control or both the system and the installer.
