GB/T 328.12 - 2007 for the determination of dimensional Stability of asphalt waterproofing membranes. It specifies the required test equipment, such as measuring tools that can accurately measure dimensional changes, etc. Detailed sample preparation, including coil cutting size, shape and quantity. During the test, standardize the processing conditions, such as temperature, Humidity, time, etc., and specify the timing and method of dimensional measurement. By comparing the size of the coil before and after treatment, calculate the size change rate to evaluate the size Stability of the coil. This standard provides a basis for evaluating the size change of asphalt waterproofing membranes in different environments, helps to select materials for building waterproofing projects, and ensures the stability of the coil size during engineering construction and long-term use. Maintain waterproof effect.
