Significance and Use
5.1 The severity of abrasive wear in any system depends on several factors: the size, shape, and hardness of the abrasive particles; the stress they apply; and how frequently they come into contact with the material. In this test method, these variables are standardized to create a consistent wear condition known as scratching abrasion. Because the method does not replicate all possible real-world conditions—such as varying particle size or shape, pressure, impact forces, or corrosive effects—it should not be used to predict the exact wear resistance of a material in a specific application. Instead, the strength of this method lies in its ability to rank materials by relative abrasion resistance under controlled conditions. If the service life of one material is already known in a given abrasive environment, its volume loss data from this test can be used as a benchmark. Comparing unknown materials against this benchmark can provide a rough estimate of their suitability—assuming abrasion is the primary cause of wear.
Scope
1.1 This 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.
1.2 Abrasion test results are reported as volume loss in cubic millimetres. Materials of higher abrasion resistance will have a lower volume loss.
1.3 The 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.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This 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.
