Activities related to the work of Consultative Committees

R.S. Davis is Executive Secretary of both the Consultative Committee for Mass and Related Quantities (CCM) and the Consultative Committee for Thermometry (CCT).

The CCM and ten of its thirteen working groups and two task groups met at the BIPM in April 2008. The CCT, all nine of its working groups and its task group met at the BIPM in May 2008.

A. Picard is coordinator for mass measurements in the International Avogadro Coordination project/CCM Working Group on the Avogadro Constant. He is a member of the steering committee of CCM/WGM-TG1, which is charged with developing a mise en pratique for a future redefinition of the kilogram.

Three members of the Mass section devote a substantial percentage of their time to the watt balance, which is one of two special projects of the BIPM:

  • A. Picard, 80 %;
  • H. Fang, 70 %;
  • A. Kiss, 100 % (since joining the Mass section in November 2007).
