Convention of the Metre and RMOs Dr. Ilya Kuselman The National Physical Laboratory of Israel (INPL) Givat Ram, Jerusalem, e-mail: ilya. kuselman@moital. gov. il http: //inpl. moital. gov. il Vice-Chair of the Co-operation on International Traceability in Analytical Chemistry (CITAC), http: //www. citac. cc Chair of the Israeli Metrological Society (IMS) http: //www. science. co. il/ims/

Traceability VIM: it is the property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties.

Convention of the Metre - 1875 elcome to the Bureau International des Poids et Mesures (BIPM). BIPM contact details: BIPM Pavillon de Breteuil 92312 Sèvres Cedex France Tel: +33 1 45 07 70 70 Fax: +33 1 45 34 20 21 The task of the BIPM is to ensure world-wide uniformity of measurements and their traceability to the International System of Units (SI). It does this with the authority of the Convention of the Metre, a diplomatic treaty between fifty-one nations, and it operates through a series of Consultative Committees, whose members are the national metrology laboratories of the Member States of the Convention, and through its own laboratory work. www. bipm. fr Dr. Ilya Kuselman - M. D. - 30. 06. 05 5

Consultative Committees (CC) 1. The CC for Electricity and Magnetism, set up in 1927 2. The CC for Photometry and Radiometry, set up in 1933 3. The CC for Thermometry, set up in 1937 4. The CC for Length, set up in 1952 5. The CC for Time and Frequency, set up in 1956 6. The CC for Ionizing Radiation, set up in 1958 7. The CC for Unites, set up in 1964 8. The CC for Mass and Related Quantities, set up in 1980 9. The CC for Amount of Substance, set up in 1993 Dr. Ilya Kuselman - M. D. - 30. 06. 05 6

Mutual Recognition Arrangement (MRA) The MRA of National Measurement Standards and of Calibration and Measurement Certificates Issued by NMIs: to establish the degree of equivalence of national measurement standards maintained by NMIs; § to provide mutual recognition of calibration and measurement certificates issued by NMIs; § thereby to provide governments and other parties with a secure technical foundation for wider agreements related to international trade, commerce and regulatory affairs. § Dr. Ilya Kuselman - M.

Conclusions 1. To establish the degree of equivalence of national measurement standards maintained by NMIs they should participate in key comparisons organized by BIPM (Consultative Committees) and by RMOs. 2. INPL is taking part in both BIPM and RMO (EUROMET) key comparisons. Dr. Ilya Kuselman - M. D. - 30. 06. 05
