The Department succeeds to a number former metrological subdivisions of the Institute, which were headed by the prominent scientists-metrologists Dr. M.F.Malikov and Dr. K.P.Shirokov who pioneered in the theory of traceability chains (charts ensuring the transfer of units of physical quantities from national standards to working measuring instruments) and worked on their normalization, as well as on the normalization of metrological terms and definitions. A significant contribution to the methods for data processing and evaluating the measurement accuracy was made by other renowned scientists of these subdivisions: S.V.Gorbatsevich, S.G.Rabinovich, Ye.F.Dolinsky, V.A.Balalayev.

At present the Department carries out investigations in the field of theoretical and applied metrology aimed at effective application of present-day approaches to evaluation of measurement accuracy, optimization of measurement procedures and at taking decisions based on measurement results, as well as at an improvement on the scientific background for measurement assurance in the gas-and-oil producing industry.

**The main lines of investigations and scientific and engineering services to other companies associated with the improvement of measurement assurance systems:**

- development of the theory of data processing and measurement error (uncertainty) evacuation in working out and normalizing the measurement procedures, calibration, verification and testing of measuring instruments;
- improvement of the theory of data processing for interlaboratory comparisons, including key comparisons of national standards;
- development of methods for testing, normalizing and validating the data processing software used in metrology;
- organization of scientific and engineering seminars on the key problems of theoretical metrology;
- theoretical justification for the application of measurement procedures ensuring the required accuracy for accounting of energy supplies under the input restraints on the basis of mathematical modeling of uncertainties in measurement of the quantity and the quality of the energy supplies;
- development of methods for economical optimization of measurement technologies applied in production, transportation and realization of oil and petroleum products and natural gas, regulation of the developed methods by drawing up normative deeds.

Most of the Department experts are members of Federal Agency for Technical Regulation and Metrology Technical Committees on Standardization and also take part in the activities of TK 206 “Measurement Standards and Hierarchical Chains” and ТК 445 “Metrology of the Energy-Effective Economy”.
