GB/T 44507-2024 specifies the methods for determining and evaluating the surface scratch resistance of artificial leather, synthetic leather, and their products, including three test methods: the metal finger scratch method (Method A), the paper clip scratch method (Method B), and the rotary scratch method (Method C). The standard simulates scratching scenarios under different usage conditions and evaluates the scratch resistance level based on the surface damage state. It is applicable to the quality inspection of various related materials and products. The tests require specialized scratch resistance testing equipment (equipped with tungsten carbide metal fingers, paper clip scratch heads, or rotary scratch blades), precise weights, sample fixing devices, and evaluation light boxes, among other instruments. By controlling specified load and speed parameters, the standard provides a unified technical basis for material development and quality control.
