BIPM News:
BIPM - TÜBİTAK UME project placements completed with great success and extended to 2021: other NMIs encouraged to offer placements. The joint "BIPM - TÜBİTAK UME project placements" initiative has been extended to 2020 and 2021 following the success of the 2018 and 2019 cycles. Given the significant demand for capacity building and knowledge transfer training, the BIPM invites other NMIs to join this initiative. Most accurate CO2 measurements thanks to isotopic analysis A recent publication from the BIPM demonstrates how the isotopic composition of CO2 in air standards can be used to correct precise spectroscopic measurements to achieve the highly accurate assignment of CO2 concentrations in air. Precision measurements in the search for signs of new physics with CERN's ATLAS detector The BIPM was very pleased to welcome Prof. Manuella Vincter from CERN, on 29 July 2019, to give a seminar on the ATLAS experiment, which is one of the largest and most complex scientific instruments ever constructed. The aim of the experiment is to study the fundamental properties of matter, leading to a better understanding of our world and the history of the universe. 19th International Metrology Congress - Paris, 24 to 26 September 2019 As every two years, the CIM is going to take stock of the recent advances and future perspectives in the field of scientific and industrial metrology through a diverse and specifically selected conference programme complemented by round table sessions and keynote talks dedicated to key societal and metrological challenges. The complete conference programme can be found here.

The BIPM's mission and role:

  • Our vision is to be universally recognized as the world focus for the international system of measurement.

  • Our mission is to work with the NMIs of our Member States, the RMOs and strategic partners world-wide and to use the BIPM's international and impartial status to promote and advance the global comparability of measurements.
