...Abstract Abstract This chapter reviews the tests and procedures used for measuring hardness of plastics and elastomers. The conventional testing methods (Rockwell, Vickers, Brinell, and Knoop) used for testing of metals are based on the idea that hardness represents the resistance against...

... and dynamically. A.F. Shore created the rebound hardness measuring method. E. Meyer set up the power law for the ball indentation test. 1920 S.R. Rockwell developed the test force method named after him. 1925 R. Smith and G. Sandland developed the Vickers method, which allowed microhardness testing...

... of the structure illustrated is listed in the accompanying table in most cases. Vickers hardness usually can be determined easily for the material at hand. It is desirable, however, to be aware of the usefulness and limitations of hardness testing. Tabor ( Ref 5 ) has shown that the Vickers indentation hardness...

... and the indentation diameter measured. A hard material produces a small indentation. The Vickers test relies on small indents measured through a microscope; it is a microhardness test. The indenter is placed on microscopic targets, such as individual phases. Evaluation of hardness versus position using small movement...
... microhardness is required, the Vickers indent is recommended. This makes testing of the HRC 50 equivalent easier in the relatively large hardness transition zones produced during induction hardening. With the Vickers test, polishing to 600 grit will produce a specimen surface smooth enough for a good test...
