The Vickers hardness test

The Vickers hardness test was developed in 1921 as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is 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.

The Vickers hardness test uses a 136° pyramidal diamond indenter that forms a square indent. The load is applied for a time of 10–15 s. The two axes of the diamond shaped indentation measured in millimetres are averaged (to give the dimension d) and the hardness is determined, based on a calibration for different kilogram loads (P). The hardness (HV) is expressed as, e.g., HV 10, for a 10 kg load, or HV 5 for a 5 kg load.
