GB/T 328.14-2007 "Test Methods for Building Waterproofing Sheets - Part 14: Bitumen Waterproofing Sheets - Low Temperature Flexibility" specifies the method for testing the flexibility of bitumen waterproofing sheets under low-temperature conditions. This method involves bending the test specimen around a specified diameter bending rod or bending plate at a designated low temperature to inspect whether cracks occur in the coating layer and the base material, which serves as a key indicator for evaluating its low-temperature crack resistance.
