GB/T 41878 - 2022 Specifies the measurement of scratch performance of plastics. It specifies the preparatory requirements of the sample to ensure that it can accurately reflect the true characteristics of the plastic. Specify the accuracy and specifications of the required test equipment, and carefully describe the scratch test process, including the selection of scratch tools, the size of the force applied, the scratch speed and the measurement and evaluation method. Through this standard, the scratch resistance of plastics can be accurately determined, providing key performance data for the application of plastics in areas prone to surface damage such as electronic products, furniture, automotive interiors, etc., to help product design optimization and mass improvement.
