GB/T 18242-2025 specifies the technical requirements, test methods, marking, packaging, and storage for polymer-modified bitumen waterproofing sheets using elastomers (such as SBS) or plastomers (such as APP). It covers key performance indicators for such sheets, including physical properties (such as tensile strength, elongation, and low-temperature flexibility), heat resistance, and puncture resistance, serving as the basis for the production and inspection of these mainstream waterproofing sheets.
