Abstract

The methods of processing the results of interlaboratory comparisons are described in the paper. The supplementary comparisons for national standards are carried out with the purpose of confirming measurement and calibration capabilities of the corresponding national metrology institutes. The Guideline on COOMET supplementary comparison evaluation does not take into account the presence of systematic error in the results of comparisons. The Guidelines on "Comparisons of groups of instruments for calibration of the same accuracy level" (MI 1832-88) take into account a systematic component of the measurement error, but the results of comparisons are not verified for consistency, which is an objective confirmation of stated uncertainties. Thus, we propose to combine these two methods for objective demonstration of measuring data reliability. To confirm the method selected for processing the comparisons results, an experiment was conducted, comparisons of voltmeters of one accuracy class with higher accuracy class were made. The results of comparisons and their processing by the proposed combined method are given in the paper. Thus, the proposed method allows evaluating the systematic component of uncertainty and its correction, hence, the laboratory comparisons data are recognized as such that confirm given uncertainties.
