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: a) with counterface wheels of different stiffness (for example steel and rubber); b) wet and dry; c) different abrasive sizes; d) different chemical environments.
