The ASTM D1474-2018 standard describes a method for measuring indentation Hardness of organic coatings, applicable to coatings on rigid substrates. Test methods include Knoop Hardness (Method A) and Pfund Hardness (Method B). The standard emphasizes that the two methods have a consistent ordering of coating Hardness and apply to different Hardness ranges. The standard specifies the use of SI or inch-pound units and alerts users to safety, health and Environmental requirements.
