Scope

This Standard describes a method for determining the abrasion resistance of rubber with
a vertically driven abrasive disc.
The wheel-shaped rubber specimen and the grinding disc are perpendicular to each
other and are pressed against each other according to the set load. Abrasion mass loss
is determined by setting different slip angles, rotational speeds and certain loads
between the wheel-shaped specimen and the grinding disc for slippage. Test results are
expressed in terms of mass loss per unit run distance and/or abrasion resistance index
compared to a reference compound.
This document applies to comparative testing, quality control, normative compliance
testing, arbitration testing, and R and D work.
Since the test device can independently set various wear parameters, such as: slip angle,
grinding disc rotation speed and load, this method can be widely used in the wear test
of various rubber products (especially tires).
