This standard specifies a precision test method for determining the wear resistance of rubber. It primarily employs a vertically driven abrasive disc test machine, where wheel-shaped rubber specimens are pressed and slid against a vertically mounted abrasive disc at a specific angle (slip angle) and speed under a set load to simulate complex wear conditions. By precisely controlling key parameters such as slip angle, rotational speed, and load, this method is particularly suitable for quality control and comparative research and development of rubber products with stringent wear resistance requirements, such as tires. The results are expressed as mass loss per unit distance or as a wear resistance index relative to a reference material. During testing, high-precision electronic analytical balances are typically used to accurately measure the mass change of specimens before and after abrasion.
