GB/T 328.14-2007 Test methods for building sheets for waterproofing—Part 14:Bitumen sheets for waterproofing-flexibility at low temperature
Abstract
This part of GB/T 328 specifies the test method for enhancing the low-temperature flexibility of asphalt roofing waterproofing membranes. Asphalt waterproofing membranes without reinforcement can also be tested according to this standard. This part requires that both the upper and lower surfaces of the membranes pass the test at a specified temperature or continue to be measured at different temperature ranges as the cold bending temperature of polarity. This part 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 performance of the product after accelerated aging.
