5.1?The 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 practice these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion 1.1?This test method covers laboratory procedures for determining the resistance of metallic materials to scratching abrasion by means of the dry sand/rubber wheel test. It is the intent of this test method to produce 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 for the particular test procedure specified. Materials of higher abrasion resistance will have a lower volume loss. Note 1:?In order to attain uniformity among laboratories, it
is the intent of this test method to require that volume loss due
to abrasion be reported only in the metric system as cubic
millimetres. 1 mm3 = 6.102 ? 10?5
in.3.
1.3?This test method covers five recommended procedures which are appropriate for specific degrees of wear resistance or thicknesses of the test material. 1.3.1?Procedure AThis is a relatively severe test which will rank metallic materials on a wide volume loss scale from low to extreme abrasion resistance. It is particularly useful in ranking materials of medium to extreme abrasion resistance. 1.3.2?Procedure BA short-term variation of Procedure A. It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials. Procedure B should be used when the volumeloss values developed by Procedure A exceeds 100 mm3. 1.3.3?Procedure CA short-term variation of Procedure A for use on thin coatings. 1.3.4?Procedure DThis is a lighter load variation of Procedure A which is particularly useful in ranking materials of low-abrasion resistance. It is also used in ranking materials of a specific generic type or materials which would be very close in the volume loss rates as developed by Procedure A. 1.3.5?Procedure EA short-term variation of Procedure B that is useful in the ranking of materials with medium- or low-abrasion resistance. 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. |
