Abstract: The quality of products for which all manufacturers are struggling is one of the important components of competitiveness. High quality of products is ensured by means of various types of measurements. Currently in the Russian Federation, in order to comply with international standards for assessing the quality of products, measures are being taken to standardize national standards in the field of ensuring the uniformity of measurements. To meet the requirements of international standards, the Russian Federation applies GOST ISO/IEC 17025-2009 "General requirements for the competence of testing and calibration laboratories” as the national standard. This document established that "calibration laboratories should have and apply the procedures for the evaluation of uncertainty in measurement accuracy". The use of "uncertainty" in assessment of the measurement accuracy allows you to clearly address the issue of compliance (non-compliance) of the measured quality characteristics to the established standards. This work is dedicated to and describes the methods of measurement of the required level of accuracy and complexity of measurements in calibration of measuring instruments. Approaches that are described in this article, do not cover all aspects of measuring instruments calibration and the establishment of real values of their parameters, including estimates of uncertainty associated with them. The procedures outlined in this paper should be considered as basic approaches to calculation and attribution values for most methods of calibration of measuring instruments, but in each case there may be a need for the relevant adjustments.
