COOPERATION WITH THE INTERNATIONAL BUREAU OF WEIGHTS AND MEASURES (BIPM)
VNIIFTRI is a national metrological institute and is actively involved in the activities of the BIPM Consultative Committees.
As the Main Metrological Center of the National Service for Time, Frequency and Determination of Earth Rotation Parameters and a member of the Consultative Committee for Time and Frequency, VNIIFTRI cooperates with the BIPM in the area of ensuring the uniformity of time and frequency measurements and in the formation of the national time scale UTC(SU).
As a member of the Consultative Committee for Thermometry, VNIIFTRI participates in the Working Group on Humidity and the Task Group for Emerging Technology. The committee deals with issues such as development and realization of the International Temperature Scale, studies of the thermodynamic scale, its extension and improvement, studies of secondary fixed points, development of international reference tables for thermocouples and resistance thermometers and improvement of humidity standards.
VNIIFTRI has observer status with the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology and participates in four Working Groups. These include the WG on Key Comparisons and CMC Quality, the WG on Electochemical Analysis, the WG on Inorganic Analysis and the WG on Gas Analysis. Within these WGs, the VNIIFTRI scientific research department for metrology of physicochemical and electrical measurements has taken part (including as a co-coordinator) in more than 15 key and supplementary comparisons and pilot studies concerning pH measurement, determination of inorganic components in various matrices, determination of the number concentration of aerosols in air, etc.
VNIIFTRI is also an Observer to the Consultative Committee for Acoustics, Ultrasound and Vibration and participates in the Working Group on RMO Coordination. The main tasks of this WG are to keep RMO members abreast of developments in acoustics, ultrasound and vibration, to resolve disagreements in the preparation and review of CMCs, to maintain a technical expert database, etc.
A COOPERATION PROGRAM WITH THE NATIONAL METROLOGY INSTITUTE OF GERMANY (PTB)
Within the framework of the Cooperation Program between the Federal Agency on Technical Regulation and Metrology (Rosstandart) and the National Metrology Institute of Germany (PTB), VNIIFTRI and PTB collaborate in the fields of high pressure studies, comparison of national nanoindentation standards, low-temperature measurement, time scale comparisons, bilateral comparisons of pH and pX measurements, measurement of the parameters of the gravitational field with highly stable time and frequency standards, etc.
The Rosstandart and PTB Cooperation Program involves the participation of six Russian state scientific and metrological institutes, with over 60 scientific research works currently in progress.
COOPERATION WITH THE INTERNATIONAL ORGANIZATION OF LEGAL METROLOGY (OILM)
VNIIFTRI actively participates in OIML work; it heads the Secretariat of OIML/TC17/SC3: pH-metry.
At VNIIFTRI, work is now underway on the revision of OIML R54 International Recommendation: pH Scale for Aqueous Solutions, 1981 Edition. The works are at the final stage
MODERNIZATION OF MEASUREMENT STANDARDS FOR UZBEKISTASN
In December 2019, VNIIFTRI and the Uzbek National Institute of Metrology (UzNIM) signed a bilateral scientific and technical cooperation agreement.
Under this arrangement, VNIIFTRI will assist Uzbekistan in building a new time and frequency standard as well as a national time service.
