Representatives of Ukrmetrteststandart Attend the 28th General Conference on Weights and Measures

The 28th General Conference on Weights and Measures (CGPM) took place in Versailles, France, from 13 to 15 October 2026. The CGPM is the highest governing body of the International Bureau of Weights and Measures (BIPM), bringing together representatives of the Member States of the Metre Convention. Held every four to six years, the conference makes key scientific, organizational and financial decisions concerning international metrology.

Ukraine was represented by two experts from the State Enterprise Ukrmetrteststandart:

• Yurii Kuzmenko, PhD, Deputy Director General for Metrology, Conformity Assessment and Research, and Ukraine's representative on the International Committee of Legal Metrology (CIML).
• Ihor Pototskyi, PhD, Director of the Scientific and Technical Institute of the National Metrology Service.
  

Key Outcomes of the Conference
The conference addressed major developments in international metrology and adopted resolutions setting priorities for future scientific and technical cooperation.

• Future redefinition of the second. Delegates reviewed progress towards redefining the SI second using optical frequency standards. A resolution was adopted calling for further work, with a proposal for redefining the second expected to be presented at the next CGPM meeting in 2030.
• International lunar reference time scale. The conference adopted a resolution on establishing an international lunar reference time scale and ensuring its metrological traceability to Coordinated Universal Time (UTC). This initiative aims to provide a common time reference for navigation and synchronization during future lunar missions.
• Digital transformation of metrology. A resolution was adopted to advance the digital transformation of the global metrology system, focusing on interoperable digital tools, machine-readable metrological information and the reliable exchange of measurement data.
• Institutional and financial matters. The conference adopted a resolution on BIPM funding for 2028–2031 and held elections for members of the International Committee for Weights and Measures (CIPM).

Ukraine's Role in International Metrology
“Participation in the General Conference on Weights and Measures strengthens Ukraine's engagement with the international metrology community and enables the country to contribute to decisions shaping the future development of the International System of Units (SI). The digital transformation of metrology and evolving international approaches to time measurement and coordination create new opportunities for scientific and technical cooperation, in which Ukraine should play an active role,” said Yurii Kuzmenko following the conference.
