Hardness Test Blocks

Hardness test blocks are reference standards used to calibrate hardness testers, such as Rockwell hardness testers, Brinell hardness testers, and Vickers hardness testers. They are made of 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 test blocks are typically supplied with certification from a recognized laboratory, confirming their hardness value.
