Abstract
This paper presents a case study on the metrological comparison of 0.05-class digital pressure gauges.It system-atically applies the authoritative value method,arithmetic mean method,weighted mean method,and median method recommended in Appendix D of JJF 1117-2010 Measurement Comparison to calculate the reference values.A comparative analysis is conduct-ed on the differences in the derived values and their associated uncertainties.Using the robust median method as a reference for verification,the results indicate that although the reference values obtained from different methods vary,they all lie within ac-ceptable uncertainty ranges,confirming the validity of each approach.Based on the findings,the paper further proposes an ac-ceptability criterion for assessing the consistency of reference values,offering methodological guidance for the practice of metro-logical comparison.关键词
