GB/T 328.16-2007 "Test methods for building waterproof sheets - Part 16: Polymer waterproof sheets - Resistance to chemical liquids (including water)" specifies the test methods for evaluating the resistance of polymer waterproof sheets to chemical liquids (including water). The method involves immersing specimens in specific chemical liquids (such as acid, alkali, or salt solutions) or water at specified concentrations and temperatures for a defined period. After immersion, changes in appearance, mass, and dimensions, as well as the retention rate of physical properties (such as tensile strength and elongation at break), are measured to assess the chemical stability of the material.
