[no.27] Report from the Chaireperson of APMP
Report from the Chaireperson of APMP

The 10th meeting of the JCRB was held at NMIJ/AIST, Tsukuba Japan on 3-4 March, 2003. This will be recorded as the first official meeting held in Japan under the Metre Convention. In this connection, some meetings of APMP such as DEC (Developing EconomiesÕ Committee) and TC chairs were held. Member laboratories and the Secretariat of the APMP had rather busy time this spring to participate in these important events. These events include commemorate symposium and ceremony celebrating the centenary of the foundation of NMI in Japan. Details of some events mentioned above are reported in this newsletter by separate articles.

As a part of APMP activities, the chairperson and the executive secretary attended some international conferences such as IMEKO World Congress and NCSLI to present papers and to join technical programs. Another new approach of APMP is to hold a joint workshop concerning quality system management of NMIs between APMP and other RMOs such as SIM under the APEC TILF funding.

In these few years we are concentrating on the activities to establish global CIPM/MRA and have got some suitable experience through exchange of information and meetings. In this stage, we have to remind the basic concept of ours to fulfill the requirements of CIPM/MRA to show the equivalence of national measurement standards with technical competence and quality system management through harmonized inter-regional reviews of CMCs. Here, the chairperson is reporting the results of some meetings and events.

10th JCRB meeting at NMIJ/AIST, Tsukuba, Japan
Recently, we have meetings of JCRB twice a year, and its 10th meeting was held on 3-4 March at Tsukuba by the invitation from NMIJ/AIST and APMP in Asia Pacific region. As we are now in the final stage towards the end of transition period for the CMC submission to enter into the BIPM Key Comparison Database(KCDB), condensed or review discussion was held at the 10th mee The terms of reference for the JCRB can be summarized once again as the documentation and review of requirements to show the technical competence together with the quality system management. At the 10th JCRB meeting, the chairman of the JCRB submitted a paper on the role of supplementary comparisons organized by RMOs.
Symposium and celebration ceremony for the centenary of NMI in Japan
In Japan, former National Research Laboratory of Metrology (now, amalgamated into National Metrology Institute of Japan in AIST) was established in 1903. Through the year of 2003, NMIJ is celebrating this centenary by organizing some international symposium/seminar and meetings. On the fifth March, international seminar on the global MRA was taken place by inviting the director of the BIPM, Dr. T. Quinn as a guest speaker. The chairperson and the former executive secretary of the APMP made presentations on the activity of the APMP and the role of APEC economies to the global MRA, respectively. There were more than 300 participants from member laboratories of APMP and domestic laboratories & industries.

DEC meeting
By the call of the chairman, Mr. Van of VMI, DEC meeting was held on 6th March at NMIJ/AIST. About 30 participants from member economies attended this meeting, and discussed on the urgent requirements of the committee. As the result of the meeting, they are preparing some programs of regional key comparisons and training of technical experts. The chairperson and executive secretary of APMP visited several member economies in these few years to learn their background and to collect their requirements. This action is surely helpful to support DEC members including to get consensus with their governmental administrative staff.

TC Chairs meeting
TC chairs meeting was also taken place on 24-25 March at NMIJ by the participation of all 11 TC chairs. Usually, at the occasion of General Assembly of APMP, TC chairs meeting is held together with EC meeting. This time, all 11 TC chairs gathered and two day meeting was held at NMIJ/AIST Tsukuba on 24-25 March 2003. They discussed the concept and review process to submit CMC into KCDB. The technical issues on intra-regional and inter-regional review process for CMCs were also discussed.

Centenary Ceremony of the Foundation of NMI in Japan
On the occasion of World Metrology Day, 20th May, NMIJ celebrated its centenary in Tokyo by inviting many leading persons in the world metrology both from overseas and nationwide. At the memorial symposium, a Novel Prize Owner in 2002 in the field of Chemistry, Dr. Koichi Tanaka of Shimadzu Corporation made a lecture on the fundamentals of chemical analysis using laser mass spectroscopy. In this connection, meeting of National Metrology Board of Japan was also held at the same place.

IMEKO 17th World Congress, at Cavtat/Dubrovnik, Croatia
The 17th IMEKO(International Measurement Confederation) world congress was held at Cavtat/Dubrovnik, Croatia on 23-27 June 2003. During the Congress, there were two kinds of opportunities to introduce the recent activity of APMP. As the round table discussion, ÒThe Emerging Global Metrology SystemÓ was organized by TC11(Metrological Infrastructures) and TC1(Education and Training), following four presentations were made:
*Global challenges to metrology: E. Seiler, Chairman of IMEKO TC 11, PTB
*From the SI to a global system: T. Quinn, Director of the BIPM
*Regional Metrology cooperation in metrology: H. Imai, Chairperson of APMP, AIST
*The role of accreditation in metrology: J. Drnovsk, Vice-Chairman of IMEKO TC11,
@In this round table discussion, the basic role of SI for disseminating metrological standards was raised. Another technical meeting on the role of regional metrology organizations(RMOs) was held by the participation from EUROMET, APMP and others. Basic concept of measurement science(metrology), traceability and the importance of human resources were discussed. IMEKO covers many fields of measurement standards such as length, time, mass, electricity, temperature, force, pressure and so on together with advanced technology related measurement science.

Workshop on QS as a Joint Workshop between APMP and SIM organized in the APEC program
Under the APEC TILF program, a joint workshop on quality system between APMP and SIM was planned and this first trial was held in July and August 2003 at Ottawa, Canada to harmonize the concept and procedure for preparing and reviewing CMCs to submit them into BIPM KCDB. Lecturers on specific quantities such as length, electricity and so on from both APMP and SIM presented basic and specific requirements for CMCs and quality system of NMIs.

NCSL, International 2003 Conference and Exhibition at Tampa Florida, USA
At Tampa Florida USA, NCSL, International Conference & Exhibition was held on 18-22 August. In this Conference, APMP opened a booth to exchange and disseminate information of APMPÕs activity. Other RMOs such as SIM and EUROMET attended together with other NMIs, accreditation bodies and measuring instrument suppliers. The chairperson of APMP presented a paper, in the session of comparison, titled ÒThe role of proficiency testing for calibration, testing laboratory accreditation and legal metrologyÒ in order to clarify the concept and procedure of proficiency testing as a tool of conformity assessment. In NCSLI, they are organizing many technical sessions covered by the keywords of traceability, calibration, comparison, measurement uncertainty, accreditation, and so on.
Through the above mentioned several meetings and occasions, I believe that we have got a lot of information and experence for establishing the requirements to fulfill the equivalence and transparency of submitting CMCs into KCDB of the BIPM.
As a new approach under the Metre Convention, APMP should strengthen its contribution to some joint committees such as JCGM, JCDCMAS and JCTLM by sending liaison experts.

Additional Information on the JCRB activity:
Recently(September, 2003), the chairman of the JCRB, Dr. T. Quinn director of the BIPM, published a report of a compilation documents covering the first years of operation of the JCRB(Activities of the Joint Committee of the Regional Metrology Organizations and the BIPM: JCRB 1999-2003). It contains a summary report, meeting reports of the first ten meetings of the JCRB, three annual reports of the chairman and texts of various policy documents and interpretative statements of the JCRB to the CIPM/MRA. This document covers important decisions and policies made during the four years since the signing of the CIPM MRA in October 1999. I herewith reproduce the following as useful documents to understand the activity under the JCRB.

Definition of terms used in the CIPM MRA (JCRB-8/Action 28)
Calibration and Measurement Capability(CMC)

Calibration and Measurement Capability (CMC)l
The term Calibration and Measurement Capability (CMC) as used in the CIPM MRA is defined as follows :
The CMC is the best measurement capability that is ordinarily available to customers under normal conditions,2 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 underthe 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 sometime referred to as best measurement capabilities. "

Uncertainty Determinations for CMCs
INCLUDED ARE uncertainty contributions inherent in the best ordinarily available customer device during its calibration or measurement at the National Metrology Instituie.
The actual characteristics of the device must also be considered for individual calibration certificates issued by the NMI.
EXCLUDED ARE uncertainty contributions (including transport ucertainties) associated with a customer's device before or after its calibration or measurement at the National Metrology Institute.
These contributions are not part of the calibration or measurement performed by the NMI and are therefore outside the NMI's control. It is the client's responsibility to take these extra factors into consideration.

1 Based on gReport of JCRB ad hoc Working Group on CMC Uncertaintiesh (Document JCRB-8/9) and gAPMP Proposals on Uncertainty Calculations for CMCsh (Document JCRB,8/9(3).
2 Note: This does not include the NMI's capability to measure the very best instruments.

Appendix of a letter to NMI directors of States not yet Members of the Metre Convention or Associates of the CGPM
The objectives of the CIPM MRA are: to establish the degree of equivalence of national measurement standards maintained by NMIs; to provide for the mutual recognition of calibration and measurement certificates issued by NMIs; and thereby to provide governments and other parties with a secure technical foundation for wider agreements related to international trade, commerce and regulatory affairs.

Participants recognize each other's capabilities based on the following criteria:
1. Credible participation in comparisons identified by the international measurement comunity as of key significance for particular quantities over specified ranges. Presently around 400 "key comparisons" have been designated and are being carried out by NMIs, of which about 130 have been completed.
2. Credible participation in other comparisons related to specific calibration services or that have some trade and/or @economic priority for individual countries or geographic regions: so-called "supplementary comparisons". At this time, some fifty supplementary comparisons are being undertaken.
3. Having in place for calibration services a quality system that is recognized as being international best practice, in turn based on agreed criteria.

The first of these elements provides the technical basis for recognition under Part l of the MRA. Compliance with both criteria 2 and 3 enables recognition under Part 2 of the MRA. The BIPM key comparison database (KCDB: www.bipm.org/kcdb) contains the results of key and supplementary comparisons (Appendix B), together with lists of peer,reviewed and approved calibration and measurement capabilities (CMCs) of NMIs (Appendix C). At present, there are approximately 14,000 individual CMCs published in the KCDB, all of which have undergone a process of peer evaluation by NMI experts within the Regional Metrology organizations, coordinated internationally by the "Joint Committee of the Regional Metrology Organizations and the BIPM" (the JCRB).

List of signatories to the CIPM MRA as of October, 2003
A. The Directors of the NMIs of the following 43 Member States of the Metre Convention have signed the CIPM MRA

B. International organizations that are signatories to the CIPM MRA

C. The 13 Signatories to the CIPM MRA from Associates of the CGPM
