ASTM G105-20

5.1The severity of abrasive wear in any system will depend upon the abrasive particle size, shape and hardness, the magnitude of the stress imposed by the particle, and the frequency of contact of the abrasive particle. In this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion 1.1This test method covers laboratory procedures for determining the resistance of metallic materials to scratching abrasion by means of the wet sand/rubber wheel test. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.

1.2Abrasion test results are reported as volume loss in cubic millimetres. Materials of higher abrasion resistance will have a lower volume loss.

1.3The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
