WebVickers Hardness Test. Making use of a diamond indenter, the Vickers hardness test is done with less force and more accuracy than the Brinell test. By magnifying the surface … Web√ Brinell Hardness Test. This test is one of the most widely accepted hardness tests used by a machinist. Here a ball of 10mm is used as an indenter to make an impression on the material to help calculate its Brinell hardness value. The ball is held in place for a few seconds, usually 30 seconds, while a force is applied.
