There are a number of books on the subject of hardness testing of various materials. There are also a number of standard test methods for hardness testing, including ASTM standards. These standards provide information about accuracy and errors in the testing.

Hardness tests are used for a wide variety of materials, ranging from metals to rubber.

Portable hardness test methods exist for metals.

no Berkovich hardness/indenter?

Why is there no Berkovich hardness test, with a triangular indenter, on Wikipedia? Many sites say it's the most popular nanoindentation tip. -lysdexia 22:01, 25 November 2007 (UTC)

O, here it is: Berkovich tip. -lysdexia —Preceding unsigned comment added by 69.225.251.214 (talk) 22:07, 25 November 2007 (UTC)[reply]

Hardness is not a material property

The blanket claim that hardness is not a material property is dubious despite some reliable sources making this claim. It is true that many of the individual scales for hardness do not define fundamental material properties. However, there are strong arguments to be made that hardness based upon force/area can be considered a material property^[1]. Also see various works by Nix and Gao or Oliver and Pharr for hardness based on statistically stored dislocations in the materials. — Preceding unsigned comment added by Bob Clemintime (talk • contribs) 21:55, 26 October 2019 (UTC)[reply]
