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 A This 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 B-A 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 volume–loss values developed by Procedure A exceeds 100 mm3.
1.3.3 Procedure C-A short-term variation of Procedure A
for use on thin coatings.
1.3.4 Procedure D This 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 E-A short-term variation of Procedure B that is useful in the ranking of materials with medium- or low-abrasion resistance.
