    en.wikipedia.org/wiki/Hardness_comparison

    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 .

  4. Rockwell scale - Wikipedia

    en.wikipedia.org/wiki/Rockwell_scale

    A Rockwell hardness tester. The Rockwell scale is a hardness scale 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]

  5. Brinell scale - Wikipedia

    en.wikipedia.org/wiki/Brinell_scale

    The Brinell hardness 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 (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.

    en.wikipedia.org/wiki/Mohs_scale

    Mohs hardness kit, containing one specimen of each mineral on the ten-point hardness scale. The Mohs scale (/ m oʊ z / MOHZ) of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material.

    The three tables should be united into one, with side-by-side Vickers, Brinell, Rockwell and megapascal values. 82.131.210.162 10:47, 16 June 2008 (UTC) Yes, done. Values should be taken as very approximate. I personally do not trust them. Materialscientist 07:43, 28 September 2009 (UTC)

  9. Vickers hardness test - Wikipedia

    en.wikipedia.org/wiki/Vickers_hardness_test

    The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the ...
