This standard specifies a test method for evaluating the wear resistance of plastic plates and sheets through rolling contact. The core principle involves applying a specified load to a rotating specimen via a grinding wheel and quantifying its wear resistance by measuring the mass loss of the specimen after a predetermined number of rotations. Implementing this standard requires a specialized rolling wear tester, which mainly consists of a rotating disk, grinding wheel, loading device, and debris suction device. Among these, the rotating disk operates at a standardized speed, while the grinding wheel applies a stable load to the specimen through a specific geometric mounting position. This method provides a unified testing basis for assessing the wear resistance of plastic materials.
