- Abstract:
- The geometric parameters of 28 candidate Standard Reference Material (SRM) Rockwell hardness diamond indenters are calibrated by an automated system recently developed at the National Institute of Standards and Technology (NIST). The calibration results show that the cone flank straightness is a key issue for the calibrated indenters to be qualified for the geometrical specifications of NIST SRM diamond indenters. The effect of selecting different window sizes and locations for the evaluation of cone flank straightness is discussed.
