1.1 ,This test method covers the measurement of abrasion resistance of rubbers (vulcanized thermoset rubbers and thermoplastic elastomers) that are subject to abrasive/frictional wear in actual service. The abrasion resistance is measured by simultaneously moving 4 test pieces across the surface of abrasive sheets in a soft lissajous movement, and is expressed as volume loss in cubic millimeters where a smaller number indicates better abrasion resistance.
