Hardness testing standards

Hardness testing standards are established guidelines that specify how to measure a material’s resistance to deformation or scratching. These standards ensure consistency and accuracy when assessing the hardness of metals and other materials. Different standards cover various testing methods (like scratch, indentation, or rebound tests) and detail how to prepare samples, perform tests, and interpret results. They are maintained by organizations such as ASTM, ISO, or JIS, enabling manufacturers and inspectors worldwide to produce reliable, comparable data for quality control and material selection.
