This document specifies a generic test method to determine the abrasion wear characteristics of hardmetals.

The test is appropriate for use in situations where test laboratories have a need to simulate abrasive damage. The procedure includes information which enables the test to be used in a variety of different conditions:

  1. with counterface wheels of different stiffness (for example steel and rubber);

  2. wet and dry;

  3. different abrasive sizes;

  4. different chemical environments.
