- Scope
- This part of GB/T 328 specifies the test method for the low-temperature flexibility of reinforced bituminous roof waterproofing membranes. Unreinforced bituminous waterproofing membranes can also be tested according to this standard. This standard requires that both the upper and lower surfaces of the coil pass the test at the specified temperature or continue to determine the cold bending temperature as the polar temperature in a different temperature range. This section can also be used to determine the minimum cold bending temperature of the product or to determine the specified cold bending temperature of the product, for example, to determine the change in the properties of the product after accelerated aging.
