“…The coupling forces between the particles transmit the pulse flow and, accordingly, transmit the shear forces and voltages. The behavior of the liquid when a shear force is applied to it is generally described as a so-called flow curve [13][14][15][16][17][18][19][20]. The latter gives a functional relationship between the applied shear force assigned to the unit area, i.e., between the mechanical stress σxz, and the gradient γ of the liquid velocity v in the direction transverse to the movement (the x axis is directed in the direction of the liquid motion, and the z axis is perpendicular to the liquid surface):…”

The issue of implementation of software for rapid assessment of uncertainty of metrological control results of measuring instruments used in the field of state metrological control and supervision in calibration and evaluation of actual metrological characteristics of operating viscosimeters was considered. An interpretation of the application of the EXCEL program and other software for the special methodology for automating uncertainty calculations developed by us was carried out, which significantly simplified the work and reduced the time spent by specialists in the metrological laboratory. Basic requirements of comparison of software for calculation, calculation and estimation of uncertainty in the realm of mathematical models of validated techniques are determined. The experimental results of the comparative analysis taking into account the set tasks are presented, the most common and effective universal software for calculating the uncertainty of the results of the experiment. The object of the study is universal software for estimating the uncertainty of measurements and other metrological characteristics of viscometers, structured by types of measurements, in the graphic programming environment. The software can be used both in laboratories and in industrial premises. The workplace can be both a metrological laboratory, the working area of which is a table with instruments, and a production room. As a rule, accredited laboratories do not have a special staff of metrologists or specialists who perfectly understand the basics of mathematical statistics and the concept of measurement uncertainty. The complexity and necessary amounts of calculations that are carried out in assessing the uncertainty of measurements require significant laboratory resources.

“…If the results of the comparison are reproduced using formulas 1, 2, 3, and 4 given above, a number of shortcomings may arise in the process, these shortcomings include the randomness of the results obtained from the measurements, the possible gross errors, the distribution patterns of the results in the process of performing some measurements, the size we can see the metrological observability of the standard in the transfer of the size, the operator effect not being taken into account during the comparison process, and a number of similar effects. Through the processing system of such results, we can see that the compared measuring instruments maintain their metrological characteristics at the specified time, or the observation factor of the inconsistency of the results to the given error deviation is very low [14].…”

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.
