Standard Test Methods for Abrasion Resistance of Organic Coatings by Falling Abrasive
ASTM D968-25
Organization:
ASTM - ASTM International
Year: 2025
Abstract: 5.1 Silica sand produces a slower rate of abrasion for organic coatings than that provided by silicon carbide. For some types of coatings, it may also provide greater differentiation. 5.2 The abrasion resistance scales produced by the two methods differ, but the methods provide approximately the same rankings of coatings for abrasion resistance. 5.3 Each of the methods has been found useful for rating the abrasion resistance of specific types of coatings. For example Method A (falling sand) has been used for rating floor coatings while Method B (falling silicon carbide) has been used for rating coatings for ship decks.

| 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: 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 14.1.1.2 and 14.2.1.2). Interlaboratory agreement is improved significantly when ranking is used in place of numerical values. Note 1: Test Method D4060 may also be used to determine the abrasion resistance of organic coatings. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses after SI units are for information only and are not considered standard. 1.5 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. 1.6 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. | |
