The fourth meeting of the JCRB was held on 20 and 21 March 2000 at NIST,
Gaithersburg, USA with 24 participants from the BIPM, CIPM, and six RMOs.
Draft
submissions to Appendix C of the Global MRA were examined at the meeting.
Discussions on the requirements for provisional entry data (cmc files),
the review process, and the desired format of data files were also conducted
based on a report by representatives of the RMOs. A position paper prepared
by the chairman of APMP and a questionnaire prepared by the chairman of
MRAAC/APMP were submitted to the meeting.
After ample discussions, the JCRB agreed on the following statement:
At its fourth meeting on 20 and 21 March 2000, the JCRB reached a unanimous
opinion that the declared objectives of the MRA must require that the CMC
data entered in Appendix C be declared fully reliable by the RMOs. Consequently,
CMC files submitted by NMI's will remain in the review and analysis loops
of the RMOs and the JCRB until such time as this is the case.

Summary of the meeting:
1. Provisional Entry to Appendix C (see Table 1)
