BIPM News:
Evolving calibration hierarchies for diabetes diagnostics Improved measurements of C-peptide could lead to benefits for people with diabetes according to a report recently published in Clinical Chemistry. Happy World Standards Day! Standards make cities smarter Each year on 14 October, the members of the IEC, ISO and ITU celebrate World Standards Day, which is a means of paying tribute to the collaborative efforts of the thousands of experts worldwide who develop the voluntary technical agreements that are published as international standards. Quantum metrology: What's in store for the next generation? The BIPM workshop The Quantum Revolution in Metrology, held from 28-29 September 2017, promoted scientific exchange between leading researchers and representatives of the National Metrology Institutes (NMIs) on quantum technologies applied to metrology, advances made in quantum standards and next generation metrology. The role of fundamental constants in redefining the SI Celebrating the work accomplished towards the proposed redefinition of the International System of Units (SI) in terms of physical constants, the BIPM organized a scientific symposium on 7 September 2017 under the auspices of the Consultative Committee for Units (CCU). First time transfer experiment with BeiDou satellites over multiple baselines The installation of two BeiDou time and frequency transfer systems at the BIPM has allowed the establishment of the first long-distance baseline for clock comparison between the NIM and the BIPM with BeiDou satellites . Agreement with the CEA List gives the BIPM access to the DOSEO platform for high-energy photon beams An agreement between the BIPM and the CEA List will allow the BIPM to operate the ongoing BIPM.RI(I)-K6 comparison for high-energy photon beams at the DOSEO platform for R&D in radiotherapy and imaging technologies.

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.
