    1. Scope

    1.1 These test methods cover the determination of the resistance of organic coatings to abrasion produced by abrasive falling onto coatings applied to a plane rigid surface, such as a metal or glass panel.

    1.2 Two test methods based on different abrasives are covered as follows:

    Sections
    Method A-Falling Sand Abrasion Test
    Method B-Falling Silicon Carbide Abrasion Test

    1.3 These methods should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of the methods (see and ). Interlaboratory agreement is improved significantly when ranking is used in place of numerical values.

    1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.5 This standard does not purport to address 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.
