- Abstract:
- The establishment of traceability in hardness measurement is still under discussion at the ISO TC 164 SC 3 subcommittee on hardness testing. Two paths for establishing traceability are proposed for Rockwell hardness measurement in ISO 6508-1. One way is to take a route to SI units through direct calibration of machine components; the other way is to take a route to the hardness measurement standard through indirect calibration of machine performance. This confusion is partly caused by the characteristics of hardness; i.e., a procedure dependent property. In this paper, methods for the establishment of traceability for Rockwell, Brinell, and Vickers hardness measurements are discussed based on the concepts defined in the international vocabulary of metrology (VIM).
