Concluding a hardness test using a popular method like the Brinell hardness test requires measuring the indentation left on the material surface by the load applied. Though several other hardness testing methods are available, the Brinell hardness test and how to read and .The test provides numerical results to quantify the hardness of a material, which is expressed by the Brinell hardness number – HB. The Brinell hardness number is designated by the most commonly used test standards (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten .
In the Brinell hardness test, an optical method, the size of indentation left by the indenter is measured. In contrast to the likewise optical Vickers method,which involves a pyramid-shaped indenter being pressed into a specimen, the Brinell method uses a spherical indenter.
Hardness testing within the realm of materials testing. Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion .Brinell hardness test is one of indentation hardness tests, that has been developed for hardness testing.
