The ASTM D5178-2021 standard provides a method for determining the abrasion resistance of organic coatings. This method is suitable for coatings on smooth, flat surfaces, and results are expressed in tear force films. The standard emphasizes that this method is suitable for distinguishing the degree of damage to coatings, but not for powder coatings. Test results are in inches-pounds and SI units are for reference only. Users are expected to follow safety and health practices and confirm regulatory applicability before use.
