A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .
The Brinell hardness test (pronounced / b r ə ˈ n ɛ l /) measures the indentation hardness of materials. It determines hardness through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science. The hardness scale is expressed as the Brinell Hardness Number ...

Meyer hardness test; Rockwell hardness test (HR), principally used in the USA. HRA, HRB and HRC scales are most widely used. [9] Shore hardness test, for polymers, widely used in the rubber industry. [10] Barcol hardness test, for composite materials. There is, in general, no simple relationship between the results of different hardness tests.
The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [ 1 ]
