The 2.54*2.54cm square test piece is pre-ground after the test machine, and the test piece and the friction device area are run-in after adding a certain load, and the number of grinding wheels required to reach the certain wear depth of the test piece is observed, and then the wear resistance is evaluated.

Standard basis: ASTM-D1630
