This standard describes a precise method for determining the wear resistance of rubber, with its core being the use of the "Improved Lambourn Abrasion Tester." This method involves rotating a disk-shaped rubber specimen and a grinding wheel in opposite directions at different linear speeds under a specific load, thereby generating precisely controlled relative slip at the contact surface to simulate harsh friction conditions. During the testing process, an anti-sticking material is often sprayed into the friction surface gap to prevent the accumulation of wear particles. The test results are ultimately expressed as volume wear loss per unit time or as a wear resistance index relative to a standard rubber compound. This method is particularly suitable for evaluating products with high wear resistance requirements, such as tire rubber compounds.
