53.083.1 MATHEMATICAL ALGORITHM FOR PREDICTING THE CALIBRATION INTERVAL AND METROLOGICAL ACCURACY OF GAS ANALYZERS BASED ON INTERNATIONAL RECOMMENDATIONS ILAC-G24:2022/OIML D 10:2022 (E)

Аннотация

This research work analyzes the issues of establishing the calibration interval of measuring instruments and predicting metrological accuracy. The issue of implementing the methods given in the international recommendations ILAC-G24:2022/OIML D 10:2022 (E) using experimental measurements is considered. In order to analyze the calibration process over the years, the maximum permissible limits of measurement accuracy were determined, decision rules were introduced, and factors influencing the results were studied. Based on the results of calibration of the gas analyzer “KASKAD-N 31.4” for the oxide component of nitrogen in 2022 and 2023, the expected calibration period is predicted in 2024. Based on the results of theoretical and experimental analysis, an algorithm for predicting the calibration interval was formed
