Research on dispersion in indenter and reference block for Rockwell hardness test
AbstractIn this report, the Rockwell indenters and hardness reference blocks obtained from different three manufacturers were evaluated. And these results with the tolerances for the indirect verification prescribed in ISO 6508-2 and ASTM E18 were compared, it has been suggested that the tolerances prescribed in ASTM E18 might be too strict in view of actual circumstances.
