DANSK DS/ISO 21751 PDF

This International Standard specifies a strip-bend test method for the determination of the cohesive resistance of assemblies of pipe and electrofusion fittings and saddle fittings intended for the conveyance of fluids. NOTE The aim of the strip-bend test method is to provide a quick check in order to have a first impression of the quality of the connection between pipe and electrofusion fitting. The results of this test, however, cannot be quantitatively related to the required quality levels given in the relevant product standards for these types of connections.
