This standard comprehensively regulates synthetic resin-based and polymer cement composite flooring materials applied on substrates such as cement mortar and concrete, used for ground decoration, protection, and providing special functions (e.g., anti-static, anti-slip). It specifies in detail the product's terminology and definitions, classification and labeling, technical requirements, corresponding test methods, inspection rules, and product packaging, storage, and transportation. When conducting inspections in accordance with this standard, a series of testing instruments will be involved, including universal testing machines (for testing tensile bond strength, etc.), abrasion testers, and hardness testers for evaluating mechanical properties; xenon arc lamp aging test chambers for testing weather resistance and chemical resistance; gloss meters and friction coefficient testers for measuring surface properties; and chemical analysis equipment such as gas chromatographs for analyzing harmful substance limits.
