Wear resistance Elastomer Research Testing BV
Wear resistance is measured with a DIN abrasion test. This test involves exposing the rubber test material to a rotating drum covered with abrasive paper. After being exposed to exactly 40 meters of abrasive paper, the volume of wear in mm 3 is measured. The test is carried out according to ISO standard 4649 unless otherwise desired.

Rubber Abrasion Resistance IntechOpen
rubber abraded is proportional to the distance of sliding between rubber and counterface. However, wear of tires and abrasion on certain laboratory abrasion machines (e.g. the Akron abrader) brings into play gross properties of tire or t est piece which affect the rate of wear just as much as does the abrasion resistance of the compound.
