“…In comparison and calibration laboratories, it is recommended to use a quantity at risk less than 5% of the cases, with a false rejection probability of less than 2.5%. Based on these, we can make the following decision-making graph (Figure 3) for comparison and calibration laboratories [4]. So, we can conclude from this graph that if the measurement result is between the lower protection line and 0, the measuring tool is in compliance with the requirement, and if the measurement result is between the required accuracy limit (the upper limit of the error of the measuring tool) and the lower protection line, the measuring tool is conditionally in compliance with the requirement, the measurement result is high protection.…”

“…We know that currently, in the processing of comparison results, the concept of error is promoted in the countries of the Commonwealth of Independent States, according to which the permissible absolute error and relative errors of the measuring instrument are calculated, and these indicators are adjusted to the accuracy indicators specified by the manufacturer, and comparison certificates are issued. Basic absolute error value when processing comparison results according to GOST 8.618 [1][2][3][4][5] ,…”

Abstract. In the work done, the current state of comparison of gas analyzers was studied, and the issue of formalizing the results by making decisions based on the international recommendations of ILAC-G8:09/2019 was studied. The problems arising in the processing of the results of the comparison of gas analyzers are studied, and recommendations are given to consider the risks affecting them. Differences, shortcomings, and advances between benchmarking and calibration are discussed. No need for repeated comparison of calibrated dies, recognition of calibration result during comparison was studied. The difference between measurement uncertainty and error was studied. Making decisions on the basis of international recommendations ILAC-G8:09/2019 in the application of measurement results in the process of comparison of measurement uncertainty. Recommendations are made for establishing a line of defense in decision-making. At the National Institute of Metrology of Uzbekistan, the experimental results were processed and decisions were made based on the international recommendations of ILAC-G8:09/2019. The importance of selection of calibration points in comparison was studied and recommendations were made.
