The National Institute of Metrology (Thailand) (NIMT) further advanced international cooperation in metrology by delivering a comprehensive technical training programme in Time and Frequency Metrology to the Uzbek National Institute of Metrology (UzNIM) from 9–20 February 2026 in Tashkent, Republic of Uzbekistan.
The two-week programme was conducted under the Physikalisch-Technische Bundesanstalt (PTB) project “Support for the Reform of the National Quality Infrastructure and Development of Services for the Uzbek Economy (Phase II)”, which aims to strengthen national measurement capabilities and quality infrastructure in Uzbekistan.
The training was delivered by Dr. Thayathip Thongtan, Senior Metrologist from NIMT, and focused on enhancing UzNIM’s technical knowledge and practical skills in time and frequency measurements, particularly in the calibration of period meters and frequency counters operating in period measurement mode.
The programme combined in-depth lectures and hands-on workshops covering:
– Fundamental principles of time and frequency metrology
– SI traceability to the second and linkage to UTC time scales
– Systems for period meter calibration
– Determination of period measurement errors
– Development of uncertainty budgets
– Drafting of calibration procedures for period measurements
UzNIM maintains the national time scale, UTC(UZ), and contributes to international time scales through participation in the framework of the International Bureau of Weights and Measures (BIPM). The training further strengthened SI traceability to the second and reinforced the linkage between national standards and international timekeeping systems.
During the mission, detailed discussions were held on measurement uncertainty evaluation, traceability statements, laboratory environmental controls, and the future expansion of period measurement services. UzNIM staff demonstrated strong technical commitment and presented a clear roadmap for extending period calibration services to wider ranges, with full traceability to the SI second and Coordinated Universal Time (UTC).
This technical cooperation served as an important platform for experience sharing between time and frequency experts of NIMT and UzNIM. It contributes directly to capacity building, harmonisation of measurement practices, and the sustainable development of national time and frequency calibration services in Uzbekistan.
The successful completion of the Time and Frequency metrology training marks a significant milestone in strengthening UzNIM’s technical capabilities in period measurement and calibration. It also reaffirms the strong collaborative partnership among NIMT, PTB, and UzNIM, laying a solid foundation for continued cooperation and future joint initiatives in the field of time and frequency metrology.
