Abstract
Based on the Rockwell diamond indenter's microform calibrations recently developed at NIST, as well as a deadweight standardized Rockwell hardness machine, the NIST Rockwell hardness standard calibration has been established. Our approach makes it possible to control the uniformity and reproducibility of Rockwell hardness standards through fundamental metrology rather than by performance comparisons.
