GB/T 328.15-2007 "Test Methods for Building Waterproofing Sheets - Part 15: Polymer-Modified Bitumen Sheets - Cold Bending" specifies the method for testing the bending performance of polymer-modified waterproofing sheets under low-temperature conditions. This method involves freezing the sample at a specified low temperature, then bending it 180 degrees on a bending device with a specified radius, and observing whether cracks or fractures occur on its surface. This evaluation assesses the flexibility of the sheet during low-temperature construction or use.
