Hardness Blocks Standards

Hardness standard blocks are reference standards used for calibrating hardness testers, such as Rockwell, Brinell, and Vickers hardness testers. They are made from materials with known hardness values and are used to verify the accuracy of hardness testers, as well as to standardize hardness measurements across different operators, locations, and time. Hardness standard blocks are usually provided with certification from a recognized laboratory, confirming their hardness value.
