1.12. The International System of Units (SI) - the system of units accepted by the General conference on measures and scales, based on the International system of sizes and including names and designations, sets of prefixes, their names, designation and the rule of application;
1.13. technique (method) of measurements - set of the described transactions in case of measurements which accomplishment provides results of measurements with the established indicators of accuracy of measurements;
1.14. metrological assessment - set of works, the measurements taken for the purpose of ensuring unity;
1.15. metrological traceability - property of result of measurement according to which this result can be correlated to national standard of unit of size or other basis for comparison through documentary indissoluble chain of checkings of measuring instruments and (or) calibrations;
1.16. metrological service - set organizationally and (or) the legal entities who are functionally connected among themselves, their structural divisions or structural division of state body, other legal entity which activities are aimed at providing unity of measurements;
1.17. the metrological characteristic of measuring instrument - the characteristic of one of properties of measuring instrument influencing result of measurements;
1.18. metrological examination - work by metrological assessment during which the analysis and assessment of correctness and completeness of application of the metrological requirements connected with ensuring unity of measurements are carried out;
1.19. metrological requirements - quantitative and (or) high-quality requirements (verbal and (or) digital indicators, standard rates, rules, classifications, verbal and graphical descriptions) to the characteristics of properties of national standards of units of sizes, standards of units of sizes, standard samples, measuring instruments, techniques (methods) of measurements influencing result of measurements and to conditions under which these characteristics shall be provided, and also to the measured products parameters;
1.20. metrological audit - work according to the analysis of ensuring unity of measurements in case of production, performance of works and (or) rendering services;
1.21. metrology - science about measurements, methods and means of ensuring of their unity, methods of achievement of required accuracy of measurements;
1.22. national metrological institute - the legal entity subordinated to Gosstandart to who functions on carrying out basic and applied scientific research in the field of metrology are assigned, to enhancement of scientific and methodical bases of ensuring unity of measurements and other functions in the field of ensuring unity of measurements according to this Law, other acts of the legislation, international treaties of the Republic of Belarus, and also the international legal acts constituting the right of the Eurasian Economic Union (further, unless otherwise specified, - the right of the Eurasian Economic Union);
1.23. national standard of unit of size - the size unit standard approved by Gosstandart and held for use as basis for attributing of value of size to other standards of units of sizes of the same sort;
1.24. ensuring unity of measurements - the activities directed to achievement and maintenance of unity of measurements according to requirements of the legislation on ensuring unity of measurements, international treaties of the Republic of Belarus, and also the right of the Eurasian Economic Union;
1.25. mandatory metrological requirements - the metrological requirements specified in the description like measuring instrument or the description like standard sample and obligatory for observance in the territory of the Republic of Belarus;
