Abstract

Abstract

Given the problems faced by the indentation depth testing device in the calibration process, through a large number of experiments and data research, we propose to use the grade 2 gauge block combined with mechanical comparator and bench to calibrate the indicated value error, and evaluate the measurement uncertainty of the indicated value error, and the method fully meets the calibration requirements.
