ASTM G171-03 -Standard Testing Instruments

ASTM G171 describes the method used for scratch hardness testing of materials with the help of a diamond stylus under controlled loading conditions. The test studies a material’s resistance against surface scratching and deformation, which is important for coatings, metals, plastics, and protective surface applications. It is widely used in research, manufacturing, and quality analysis where surface durability affects product performance and appearance. Presto Instruments offers advanced scratch hardness testing solutions suitable for ASTM G171 laboratory applications. These systems support controlled force application and accurate surface evaluation for detailed material analysis. Presto Instruments helps manufacturers study coating durability, scratch resistance, and surface quality before commercial use.
