GB/T 328.24-2007 "Test Methods for Building Waterproofing Sheets - Part 24: Bitumen and Polymer Waterproofing Sheets - Impact Resistance" specifies the method for testing the resistance of bitumen and polymer waterproofing sheets to dynamic impact loads. This method typically employs the drop hammer or drop ball technique, where a weight or steel ball of specified mass is allowed to fall freely from a designated height to impact the sheet specimen. The specimen is then inspected for perforation or cracking to simulate instantaneous loads that may be encountered during construction or use, such as falling objects or gravel impact.
