Abstract
Standard Rockwell diamond indenter plays an important role for a worldwide unified Rockwell hardness scale. In 1994, NIST established a microform calibration system with sufficiently small calibration uncertainty for the calibration of standard Rockwell indenters. In 1995, NIST established a group of Rockwell diamond indenters characterized both by high geometrical uniformity and hardness performance uniformity. One of them, No. 3581, was selected as the NIST s primary Rockwell diamond indenter for the calibration of NIST s Standard Reference Material (SRM) Rockwell C hardness blocks. This indenter was re-calibrated in 1997 and 2005. The calibration results showed high stability for the microform geometry of the NIST s standard Rockwell diamond indenter, as well as the high calibration reproducibility for the NIST s microform calibration system.Proceedings Title
