GB/T 328.22-2007 "Test Methods for Building Waterproofing Sheets - Part 22: Bituminous Waterproofing Sheets - Shear Resistance of Joints" specifies the test method for evaluating the resistance of lap joints in bituminous waterproofing sheets to shear stress. This method involves applying a tensile force in the shear direction to heat-welded or bonded lap joints using a tensile testing machine. The maximum shear force or shear strength at which the joint fails is measured to assess the joint's ability to withstand shear stress caused by factors such as substrate deformation under actual service conditions.
