Brinell test method used in the head by the diameter D = 10, 5, 2.5 1 mm or made of hard metal ball.By applying test force (in accordance with the test standards, from 1 kg to 3000 kg) will be the head pressure on the sample, and according to keep time to maintain it.
In order to calculate the brinell hardness, need to measure sample surface two vertical test the diameter of the indentation.In addition, also know test force N and the diameter of the spherical head.
