ASTM G-65 is a relevant abrasion resistant test for materials used in industry today. This test measures the wear due to hard particles forced against and moving along a solid surface, similar to most applications in the field.

Scope

The ASTM G-65 procedure is a three body wear test designed to produce data that will reproductively rank materials in their resistance to abrasion. Abrasion test results are reported as volume loss in cubic millimeters. Material of higher abrasion resistance will have lower volume loss.

Summary of Practice

This procedure involves the abrading of a standard test specimen with grit of controlled size and composition. The abrasive is introduced between the test specimen and a rotating wheel for 3200 revolutions with 30 lbf applied. The specimens are weighed before and after the test and loss of mass is recorded. For accurate comparison, it is necessary to convert the mass loss to volume loss in cubic millimeters due to a wide difference in the density of materials.
