Force diagram of Rockwell test A closeup of the indenter and anvil on a Rockwell-type hardness tester The Rockwell hardness test can be conducted on different types of hardness testers. [ 12 ] Benchtop hardness testers can be found either in a digital or analog model.
Brinell hardness test (HB) BHN and HBW are widely used [7] Knoop hardness test (HK), for measurement over small areas, widely used to test glass or ceramic material. [8] Janka hardness test, for wood; Meyer hardness test; Rockwell hardness test (HR), principally used in the USA. HRA, HRB and HRC scales are most widely used.
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.

Typical lectromechanical Universal Testing Machine Test fixture for three point flex test. A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing ...
The Barcol hardness test is generally used on soft materials such as rigid plastics. It measures hardness based on indentation of a sharp point with a flat tip. The test is performed using a similar method and indentation device as that used to measure Shore D hardness, however the Shore D indentor has a round tip. [4]
