- Abstract:
- The specific hardness deviations of a Rockwell diamond indenter can be determined by a group standard, consisting of several indenters, using correction functions. In this paper the establishment of an HRC group standard in the PTB and comparative investigations of the group standards in the PTB and the calibration laboratory MPA NRW in Germany are reported. Above all the group standard is advantageous for maintaining the stability of the Rockwell hardness scales.
