G65 Wear Testing

EPI Materials Testing group does custom wear testing and three standardized wear tests for their clients, ASTM G65, G105, and B611.

The G65 test is an ASTM 'Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus'. The test runs using an eight-inch wheel with a half inch of rubber on the OD of the wheel.

The ASTM G65 test includes five different tests, 'Procedure A' through 'Procedure E'. The tests differ by how long the test runs except for 'Procedure D', which uses a different amount of weight applied to the wheel.

This test runs on a variety of different materials including plating, hardbanding overlays, hard base materials, and some spray coatings.
