GB/T 40721 - 2021 is used to determine the friction performance of rubber. It regulates the preparation process of rubber samples to ensure that they can accurately reflect material characteristics. The accuracy and specifications of the required test equipment are described in detail, and the test process is clarified, including setting requirements for different test conditions such as contact pressure, sliding speed, test environment, etc. Through this standard, data such as the coefficient of friction of rubber can be accurately obtained, providing key performance references for rubber applications in tires, soles and many other fields, helping to optimize product design and improve product performance and safety.
