 Decision CIPM/107-12June 2018
It was brought to the attention of the CIPM that there is a discrepancy relating to the definition of the term "unit" between the draft 9th edition of the SI Brochure and the 8th edition. The CIPM asked the CCU President to organize a vote by correspondence among the CCU members, with a deadline of the end of August 2018, as to whether to retain the wording of the draft 9th edition or to revert to the wording of the 8th edition, and to report back to the CIPM President for further action (if necessary).

 Decision CIPM/107-14June 2018
The CIPM confirmed the working practice of inviting the Chairs of relevant Regional Technical Committees to the plenary sessions of the relevant Consultative Committees.

 Decision CIPM/107-15June 2018
The CIPM decided to adopt the following definition of consensus (which originates from the ISO/IEC Directives) for use in the Consultative Committees, Sub-committees and ad hoc Working Groups:

Consensus - "General agreement, characterized by the absence of sustained opposition to substantial issues by any important part of the concerned interests and by a process that involves seeking to take into account the views of all parties concerned and to reconcile any conflicting arguments. Consensus need not imply unanimity."

Document CIPM-D-01 will be updated accordingly.

The CIPM decided the following text for inclusion in CIPM-D-01:

In order to be informed of technical developments and evolving stakeholder needs in different areas of metrology, the CIPM has Consultative Committees with agreed scopes and the following three objectives:

  • to progress the state-of-the art by providing a global forum for NMIs to exchange information about the state of the art and best practices,
  • to define new possibilities for metrology to have impact on global measurement challenges by facilitating dialogue between the NMIs and new and established stakeholders, and
  • to demonstrate and improve the global comparability of measurements. Particularly by working with the RMOs in the context of the CIPM MRA to:
    • plan, execute and monitor KCs, and to
    • support the process of CMC review.
Document CIPM-D-01 will be updated accordingly.
 Decision CIPM/106-17October 2017
Following Decision CIPM/105-27 (on the engagement of international organizations as "liaisons" at the Consultative Committees), the CIPM decided that the status of liaison within the context of the Consultative Committees will be decided upon in each case by the CIPM.

The CIPM will base its decision on the extent to which the international organization concerned meets the following criteria:

  • being international in structure and scope of activity, and representative of the specialized field of interest in which they operate;
  • being concerned with matters covering a part, or all, of the field of activity of the BIPM;
  • having aims and purposes in conformity with the Vision, Mission and Objectives of the BIPM;
  • having a permanent directing body and secretariat, authorized representatives and systematic procedures and machinery for communicating with its membership in various countries;
  • allowing its members to exercise voting rights in relation to its policies or action or having other appropriate mechanisms to express their views; and
  • having been established at least three years before they apply for liaison status.
Organizations that are not offered liaison status within the context of the Consultative Committees will be known as "organizations in cooperation".

Document CIPM-D-01 will be updated accordingly.
 Decision CIPM/106-18October 2017

The CIPM adopted the traceability exception related to delta value isotope ratio measurements proposed by the CCQM as follows:

"Delta value isotope ratio measurements that cannot presently be made traceable to the SI should be made traceable to materials* recognised as International Standards. Since at present, values assigned to these materials are based on consensus values, these materials are not listed in the Appendix C of the BIPM Database.

* A list of certified reference materials that should be used to identify accepted references for delta value isotope ratio traceability statements is published and maintained by IUPAC:

Willi A. Brand, Tyler B. Coplen, Jochen Vogl, Martin Rosner and Thomas Prohaska

Assessment of international reference materials for isotope-ratio analysis (IUPAC Technical Report). Pure Appl. Chem. 2014; 86(3): 425-467

The report is available for free download: http://www.degruyter.com/doi/10.1515/pac-2013-1023

The CIPM notes that assigned values for replacement materials should be done through a formal internationally vetted procedure that assures the continued comparability of delta value measurements.

The CIPM encourages the continuation of programmes within the NMIs to develop absolute isotope ratio measurement values for such Reference Materials and active engagement with the IUPAC community."

 Decision CIPM/101-17June 2012
The CIPM did not agree with Recommendation 16 of the ad hoc Working Group. The CIPM is mindful that on occasions it may be necessary to seek a CC President from outside the CIPM if the appropriate skills are not available in the CIPM.
