GB/T 328.21-2007 specifies the test method for the peel resistance of joints in polymer waterproof sheets (such as TPO, PVC, EPDM, etc.). This method is used to evaluate the ability of the joint to resist peeling failure after two sheets are overlapped by means of heat welding or adhesive bonding. It assesses the quality of construction techniques and the long-term reliability of the joint by measuring the peel force.
