NIST Microform Calibration - How Does It Benefit U.S. Industry?

Abstract
In microform metrology, complex 3-D surface features in the micrometer range must be quantified for their space and size including dimensions, curves, angles, profile deviations, and alignment errors, as well as surface roughness with measurement uncertainties compatible with tolerance requirements. NIST started microform calibrations for Rockwell diamond indenters in 1994. The calibration and check standards, calibration procedures, and calibration uncertainties are introduced. NIST calibrated Rockwell indenters have been used in a US national primary Rockwell hardness testing machine, and one of these is planned for use as a common Rockwell indenter in an international round robin comparison.Proceedings Title
