(Test Method)Standard Test Method for Measuring Abrasion Resistance of Materials by Abrasive Loop Contact
Standard Test Method for Measuring Abrasion Resistance of Materials by Abrasive Loop Contact
SIGNIFICANCE AND USE
This test is useful for screening materials for use in tools that are subjected to abrasion from the material that is being machined, worked, or formed. It has been used to screen tool steels for punch press dies, hardfacings for earth-moving machinery, and wear coatings. This test utilizes a test that is simpler to build and use than those used in the Test Method G 132 abrasion test which, like this test, uses a fixed abrasive counterface to abrade a test material.
The one-hour test is intended for metals and materials that are softer than hardened steel (67 HRC), but may be applied to harder materials (see 7.1.7).
SCOPE
1.1 This test method covers ranking rigid engineering materials for abrasion resistance in rubbing against a 30-μm aluminum oxide abrasive finishing tape. Though most solids can be tested, this test method addresses its use for metals, and coatings applied to metals.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
