Abstract:The results of Guangdong Institution of Metrology taking part in ability verification program(SIMTPT2020G001)was introduced. Since the absolute value of the En value of two calibration points exceeds 0.7,we made a relatively comprehensive analysis from the aspects of the comparison sample,the measurement value of the laboratory and the uncertain evaluation. We also give our suggestions on how to evaluate the results of verifying the calibration ability.
Key words:micrometer;calibration;ability verification
