Following the end of the transition period of the CIPM MRA, i.e., after 31 December 2003 (see Document JCRB-8/13 (1)), CMCs submitted for publication on the BIPM MRA website will be required to have, as their basis, evidence of fulfilment of all of the criteria listed above in points 1 to 9.
At its 8th Meeting in March 2002, the Joint Committee of Regional Metrology Organisations and the BIPM (the JCRB) agreed that a process is required to ensure that CMCs that have already been published based on the criteria applicable during the transition period are still acceptable under the stricter criteria coming into force after the transition period and, if not, that they undergo another review (or are withdrawn from the database). Previously published CMCs are acceptable after the end of the transition period (i.e., no further review is required), if they are supported by all of the criteria listed above in points 1 to 9.
By 1 August 2003, RMO-JCRB representatives will be asked to tell the JCRB Chairman which of their RMO's published CMCs that have not met the stricter criteria coming into force after the end of the transition period and what action the RMO proposes to take to address this, such as
a) resubmission of the CMCs with new supporting evidence, to be re-evaluated via the JCRB CMC review process or
b) withdrawal of the CMCs from the database.
This is also the date by which RMOs must inform the JCRB Chairman if they require additional evidence after the end of the transition period to support CMCs of another RMO that have already been published. The JCRB Chairman will then notify the originating RMO of these requirements. In these cases, the originating RMO must inform the JCRB Chairman by the date of the JCRB meeting prior to the end of the transition period which option ((a) or (b)) above it proposes to take to address this requirement.
When CMCs require additional review and an RMO chooses option (a) above to address this, the RMO-JCRB representative is responsible for ensuring that the CMCs, with supporting evidence, are resubmitted to the JCRB Chairman no later than the date of the JCRB Meeting just prior to the end of the transition period. This evidence will then be considered in a new review of the CMCs through the JCRB CMC review process. Voting on approval of these CMCs is to be completed no later than 31 December 2003. If the CMCs are not approved at that time, the originating RMO will be required to take further corrective action.
Alternatively, if an NMI wishes to withdraw previously published CMCs at the end of the transition period, the RMO-JCRB Representative must inform the JCRB Chairman by the date of the JCRB Meeting just prior to the end of the transition period.
All actions relating to published CMCs that are to be amended in any way will be tabled by the JCRB Chairman at the JCRB Meeting prior to the end of the transition period.
Definitions of Terms Used in the CIPM MRA
PUBLISHED BY THE JOINT COMMITTEE OF REGIONAL METROLOGY ORGANISATIONS AND THE BIPM (JCRB)
Calibration and Measurement Capability2)
The term Calibration and Measurement Capability (CMC) as used in the CIPM MRA is defined below.
The CMC is the best measurement capability that is ordinarily available to customers under normal conditions,3 for example, as published in an NMI's service list and available, in principle, at any time. It should be
1. performed according to a documented procedure and an established uncertainty budget under the quality system of the NMI,
2. performed on a regular basis, and
3. available to all clients.
This is also stated in Paragraph T.7 of the CIPM MRA's Technical supplement:
"... The calibration and measurement capabilities referred to in this paragraph are those that are ordinarily available to the customers of an institute through its calibration and measurement services; they are sometimes referred to as best-measurement capabilities."
2)Based on "Report of JCRB ad hoc Working Group on CMC Uncertainties" (Document JCRB-8/9) and "APMP Proposals on Uncertainty Calculations for CMCs" (Document JCRB-8/9(3).
3)Note: This does not include the NMI's capability to measure the very best instruments.
