Apr 21, 2020· The Rockwell hardness test, according to ASTM E18-20, is an indentation hardness test that involves the use of a verified machine to force a diamond spheroconical indenter or tungsten carbide (or steel) ball indenter into the surface of a material. Hardness …

Mohs hardness test uses 10 reference materials of varying hardness as the scale for the test. The softest material used is talc (value=1) and the hardest material is diamond (value=10). Given that the references used for the Mohs scale do not have a graded increase, the Mohs scale lacks accuracy and is only a rough measure of hardness.
