GB/T 328.8-2007 "Test methodSs for building sheets for waterproofing - part 8: Bitumen sheets for waterproofing-tensile properties"

GB/T 328.8-2007 specifies the test method for the tensile performance of asphalt waterproof membranes. It specifies the equipment required for the test, such as the accuracy of the Tensile Testing Machine. For the preparation of the sample, there are clear specifications from the sampling position on the coil to the size and shape of the sample. During the test, the operation points such as tensile speed and test environmental conditions are clarified, and the calculation method of the tensile performance index is given. Through this standard, the performance of asphalt waterproof membranes under tensile force can be accurately determined, providing a key basis for its mass evaluation and engineering material selection. It is widely used in the production of waterproof membranes, building waterproof engineering and other fields.
