“…In case of conditional decisions, it is recommended to carry out the measurements again, if these results are repeated more than 3 times in conditional conditions, it is necessary to carry out measurements from another laboratory or to set the protective lines for carrying out measurements. [8][9][10][11][12] There are a number of ways to establish a line of defense for decision-making based on international recommendation ILAC-G8:09/2019, which are listed in Table 1 [1,19]. The customer can determine the amount of protection line himself…”

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.

The subject of this study is to explore modern methods for control of dynamic and kinematic viscosity of liquid media, the state of its metrological support in the republic as well as to see findings from the experiments to ensure metrological control in the International System of Units. The results from this study are found relevant for wide use in agricultural and food products, biologically active additives in assessing quality and safety, metrology. It is also considered relevant in connection with the wide use of viscosity measuring tools in the oil- and fuel industry, medicine, cosmetology, geological and construction and other industries, to evaluate the quality and safety of products, control technological processes at production sites. Scientific and practical recommendations and decisions on improvement of scientific, technical, organizational and regulatory framework of metrological provision of viscometers in the field of ensuring uniformity of measurements and its practical solutions. The findings from the study can be applied with metrological services. Based on the results of the research, metrological examination of various scientific, theoretical and functional viscometers, final conclusions were developed.
