BIPM News:
First comparisons of 18F activity using the SIR Transfer Instrument These successful comparisons took place in 2014 at the VNIIM, NPL and ENEA-LNMRI and their results were presented at the International Committee for Radionuclide Metrology (ICRM) conference in Vienna in June 2015. JCTLM session on 'Metrology and Standardization in Laboratory Diagnostics' at EuroMedLab 2015 The JCTLM organized a session on 'Metrology and Standardization in Laboratory Diagnostics' at EuroMedLab Paris 2015, one of the world's largest meetings on clinical chemistry and laboratory medicine as well as a major trade show for the IVD industry. Ms Federica Parisi awarded a master's degree for her work on the Kalman filter Ms Federica Parisi has been awarded a master's degree for her work on the application of the Kalman filter in the calculation of UTC. This work could result in a timescale with improved stability. 30 June 2015: The "longest day" in 2015 30 June 2015 will have a supplementary second following the insertion of a positive leap second to Universal Coordinated Time (UTC). First ever live broadcast of a workshop from the BIPM The BIPM's first "webinar" was broadcast on 15 June, live from the BIPM Workshop on Measurement Uncertainty.
The BIPM's mission and role:

The mission of the BIPM is to ensure and promote the global comparability of measurements, including providing a coherent international system of units for:

  • Scientific discovery and innovation,
  • Industrial manufacturing and international trade,
  • Sustaining the quality of life and the global environment.

The unique role of the BIPM enables it to achieve its mission by developing the technical and organizational infrastructure of the International System of Units (SI) as the basis for the world-wide traceability of measurement results. This is achieved both through technical activities in its laboratories and through international coordination.
