1 Scope This International Standard specifies a generic test method to determine the abrasion wear characteristics of hardmetals. The procedure complements the ASTM G65 method for dry sand/rubber wheel abrasion, the ASTM B611 method for abrasive wear resistance of cemented carbides, and the ASTM G105 method for conducting wet sand/rubber wheel abrasion tests. 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.
