GB/T 328.11 - 2007 stipulates the test method for heat resistance of asphalt waterproof membranes. The standard specifies the requirements of test equipment, such as an oven that can accurately control temperature. Standardize the preparation of samples to determine the size, shape and placement of the membrane specimens. During the test, strictly set the heating procedure, temperature retention time and other operation details. By observing whether the membrane flows, drips, slides and other phenomena at high temperature, its heat resistance is judged. This standard provides a basis for evaluating the Stability of asphalt waterproof membranes in high temperature environments, which helps to select suitable materials for building waterproofing projects to ensure that waterproof parts such as roofs play a normal waterproof effect in hot climates.
