The Akron type Rubber Abrasion Tester is in wide use since long ago. And angle is provided between the contacting surfaces of the abrasive wheel and test specimen of circular disc shape. For a given specimen and a given distance moved by abrasive surface of the abrasion wheel, the slip distance differs with this angle. The abrasion wheel and specimen are pushed against each other by means of a load and abrasion capacity for a fixed number of rotations are determined.
