GB/T 328.19-2007 "Test Methods for Building Waterproofing Membranes - Part 19: Polymer Waterproofing Membranes - Tear Resistance" specifies the test method for the tear resistance of polymer waterproofing membranes, typically using the trapezoidal tear method. This method involves creating a pre-cut notch on a standard specimen and stretching it along the two non-parallel sides of the trapezoid on a tensile testing machine until the specimen is completely torn, in order to determine its tear strength and evaluate the membrane's ability to resist the propagation of tearing under external forces.
