Scope: This document describes a method for determining the abrasion resistance of rubber using a vertically driven abrasive disc. The wheel-shaped rubber sample and the grinding disc are perpendicular to each other and are pressed against each other according to the set load. The abrasion mass loss is determined by setting the sliding between the wheel-shaped sample and the grinding disc under different side slip angles, rotation speeds and certain loads. . Test results are expressed as mass loss per unit distance traveled and/or abrasion resistance index compared to a reference compound. This document is applicable to comparison test, quality control, specification compliance test, referee test and research and development work. Since the test device can independently set various wear parameters, such as: side slip angle, grinding disc rotation speed and load, the method can be widely used in wear tests of various rubber products (especially tires).
