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. ... This test is otherwise known as the microhardness test method used for thin sections or small parts. This ... WebThe Vickers Hardness Test is similar to the Brinell method, with a square based pyramid used as the indentor. As in the Brinell test, the Vickers number is the ratio of the load to the surface area of the indentation in kilograms per square millimeter. An advantage of the Vickers test is the increased accuracy in determining the diagonal of a ...
