The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter ...

A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .
Vickers hardness test (HV) Knoop hardness test (HK) In microindentation testing, the hardness number is based on measurements made of the indent formed in the surface of the test specimen. The hardness number is based on the applied force divided by the surface area of the indent itself, giving hardness units in kgf/mm 2. Microindentation ...
The Meyer hardness test is a hardness test based upon projected area of an impression. The hardness, H {\displaystyle H} , is defined as the maximum load, P max {\displaystyle P_{\text{max}}} divided by the projected area of the indent, A p {\displaystyle A_{\text{p}}} .
