 Dr Yuning Duan, Vice President of the National Metrology Institute of
China, NIM has replaced Prof Gao Jie.

 Dr Barry Inglis will succeed Prof. Ernst Göbel as President after the
CIPM 2010 meeting, on 1 January 2011 when Prof. Kühne succeeds
Prof Wallard as BIPM Director.




                                                                         7

CIPM approved:

    Rules for the approval of new Regional Metrology Organizations.
    A policy on traceability in the CIPM MRA.



NMI Directors and CIPM agreed that the CIPM MRA needed to be
updated on the standards quoted and to reflect current practice on the
role of RMOs in relation to approval of quality systems.

              POSSIBLE CGPM RESOLUTION

1. Make a commitment formally to fix the Planck Constant, the charge
   on the electron, the Boltzmann Constant, sand the Mole/Avogadro


2. Agree that the values of the constants used will be those agreed by
   CODATA


3. Urge NMIs to resolve the discrepancies and to maintain their
   experiments, and for those without a result, to make fast progress.


4. Urge NMIs and others to do more to raise awareness

     CIPM MRA - 10 year anniversary symposium


8-9 October 2009, Paris
  • very successful MRA addressing the needs of
  industry, trade, regulators and society

                         AFRIMETS General Assembly - 2010
            BIPM Workshop on Metrology at the Nanoscale
                             18-19 February 2010, BIPM, Sèvres.


        “What activities are required to establish an effective international
              infrastructure for the metrology at the nanoscale?”
   Talks and discussions on the concepts of traceability, standardization, reference
   materials, international coordination….
   ….in 8 thematic breakout sessions : Methods and Technologies for Toxicological Testing
   of Nanoscale Materials, Nanobiotechnologies, Aerosols (airborne nanoparticles),
   Microscopy, Mechanical metrology, Nanomagnetism, Surface Analysis, Thin films and
   coatings.
   105 participants, 47 different institutes/institutions (NMIs, OECD, UC Dublin, ISO/TCs)
   or companies (Bayer, IBM, Intel, Intertox, Ionbond, JEOL)
   Some conclusions:
      Main drivers : industry and EHS issues
      Users’ expectations towards metrology community are significant. They want
      more work to establish traceability and methods
      Traceability routes/calibration services/reference materials exist but for very few
      measurements compared to the important needs

     BIPM Workshop on Physiological Quantities and SI Units
                          16 -17 November 2009, BIPM, Sevres


    Action spectrum, definition of the measurand, traceability to SI,
                     evaluation of uncertainties.
Programme: Optical radiation, Radio- and micro-waves, Ionizing radiation, Sound and
ultrasound, Magnetic fields, and Biological quantities.
Aim: exchange between NMIs and IGOs, such as ISO, IEC, CIE, ICRU, IUPAC,
IUPAP, etc.
Main findings
    On-going progress observed in all areas, but still problems for establishing
    action spectra
    Collaborative development needed (ex: the CCPR and the CIE on vision).
    Uncertainty generally not well established.
    Action spectra highly variable due to psychophysical and behavioural
    processes that affect human responses.
    Limitations in the application of the models to low level effects or in case of
    saturation effects.



                                                                                      19

 Health and safety issues drive a growing need to quantify the effects of a
                multitude of factors on the human body:
description in terms of action spectrum, definition of the measurand, traceability
                         to SI, evaluation of uncertainties.
Programme:Optical radiation, Radio- and micro-waves, Ionizing radiation, Sound and
ultrasound, Magnetic fields, and Biological quantities.
Aim: exchange between NMIs and IGOs, such as ISO, IEC, CIE, ICRU, IUPAC, IUPAP, etc.
Further steps
     Collaboration between CCs, Joint Committees (JCTLM, JCGM) and IGOs TCs field by field.
     More information on physiological quantities in the next SI Brochure.
     Harmonization of terms.
     International unification of legislation and regulation.
     Increase awareness at all levels through additional workshops and forums.

Measurement Challenges for

          March 29 – April 2                   •
    2010 – WMO, Geneva (CH)



                                               •             WMO Signing the CIPM MRA

                     30 March -1 April 2010, Genève, Switzerland


                                       Themes:
                     Traceability, Stability and Uncertainty
Outcomes:
    Measurement results from climate monitoring should be, where practical
    traceable to the SI
    The meteorological community should specify its measurement needs to
    the NMIs.
    Measurement standards should be improved to provide accuracies and
    uncertainties that meet the needs of climate scientists and, legislators and
    regulators.
    Calibrations of instruments used in the meteorological community should
    be throughout projects and not just at the beginning.
