Principle ·A (steel or super hard alloy) ball indenter is used to indent the test surface. Hardness is given as a quotient divided by the surface area of the dent, computed from the diameter. ·This standard or test load is applied via a diamond or ball indenter. Hardness is read on a tester.
·The specimen is set on a table. A hammer is dropped from a uniform height. Hardness is based on how height the hammer bounces.
