GB/T 2 2789.2 - 2023 Focusing on rigid polyvinyl chloride (PVC) boards (sheets) with a thickness of less than 1mm. The standard divides the classification of such sheets in detail, covering different uses and types of performance characteristics. Its dimensions, such as length, width tolerances, etc., are clearly specified. At the same time, various performance indicators of sheets are standardized, such as tensile strength, Vicat softening temperature, etc. It provides mass control criteria for production enterprises, which is convenient for downstream industries to select accurately according to actual needs, and promotes the rational application of rigid polyvinyl chloride (PVC) sheets in Encasement, decoration and other fields.
