Regional metrology organizations (RMOs) play an important role in the CIPM MRA. MMRs are responsible for implementing comparisons and other measures in their regions to enhance mutual trust in the validity of the calibration and measurement certificates of their member NMMs. Through the Joint COMMITTEE of RMOs and BIPM (JCRB), they carry out an interregional review of the capacities declared prior to the publication of the authorized CMCs in the CCDB and submit to the CIPM policy proposals concerning the functioning of the CIPM MRA. This agreement shall be implemented by the BIPM in close coordination with the Consular Committees and the RVO, which shall, in accordance with paragraphs 4 and 5, carry out and evaluate the results of the main comparisons. Differences of opinion resulting from the application of this Agreement shall first be discussed in the relevant Advisory Committee, the RMO or the Joint Committee and, if not resolved, referred to the CIPM. In response to economic globalization, the International Committee on Weights and Measures (CIPM) Mutual Recognition Arrangement (MRA) was signed in 1999 by the CIPM, composed of the various countries represented by the National Institutes of Metrology (NMIs) that signed the Meter Convention. This CIPM MRA is a historic agreement for wider acceptance of national measurement standards and calibration and measurement certificates issued by their institutions, thus providing governments and other parties with a secure technical basis for broader agreements on international trade, trade and regulation. For example, under the CIPM MRA, each country leaves and mutually recognizes the traceability system of the national measurement standards of other NMMms and approves the calibration data as being in balance and accepts the calibration and measurement certificates. If the test device is traceable to its own national measurement standards, the certificate of measurement and calibration of the product is also allowed in other countries.
It is an agreement between national metrology institutes which establishes conditions for the mutual recognition of national measurement standards and the recognition of the validity of calibration and measurement certificates issued by national metrology institutes. It is established by the CIPM with the power conferred on it by Article 10 (1921) of the Rules annexed to it. The CIPM MRA responds to the need for an open, transparent and comprehensive system in order to provide users with reliable quantitative information on the comparability of national measurement services and to lay the technical foundations for broader negotiated agreements for international trade, trade and regulatory issues. . . .
