GB/T 328.18-2007 "Test Methods for Building Waterproofing Membranes - Part 18: Bituminous Waterproofing Membranes - Tear Properties (Nail Shank Method)" specifies the method for determining the tear properties of bituminous waterproofing membranes using the nail shank method. This method involves threading pre-made incisions in the specimen into the grips of a tensile testing machine, securing the specimen with a nail shank at its midpoint. During stretching, stress concentration occurs at the nail shank, simulating the stress state when the membrane is hooked by a sharp object, thereby measuring its tear resistance.
