Vickers hardness test

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 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 can be used for all materials irrespective of hardness.
