Vickers Hardness Test

A hardness testing method in which the microhardness of a specimen is determined by forcing a square-shaped diamond indenter into a test specimen at a load ranging between 1 gram and 1,000 grams and measuring the diagonals formed by the square-shaped indenter and finding their average. This average is then converted into a Vickers Pyramid Number (HV) or a Diamond Pyramid Hardness Number (DPH).
