During the initial fou-r-year period, the database (which was designed by the NIST) wi-ll be held jointly by the BIPM and the NIST. Appendix A List for national metrology institutes that are signatories tothe arrangement, together with their logos. Appendix B B1: Results of CIPM key comparisons. B2: Results of RMO key comparisons. B3: Results of supplementary comparisons. For each key comparison the following are included: ．individual values for each institute together with their decl-ared uncertainties; ．the key comparison reference value with its associated uncert-ainty; ．for each institute, the deviation from the key comparison ref-erence value and the uncertainty in that deviation (at a 95%level for confidence), i.e. its degree of equivalence; ．the degress of equivalence between the standards of each of t-he participating institutes. Appendix C Quantities for which calibration and measurement certificates a-re recognized by institutes participating in part two of the ag-reement. The qUantities, ranges and calibration and measurementcapabilities expressed as an uncertainty (normally at a 95% lev-el of confidence) are listed for each participating institute.Appendix D List of key comparisons. Appendix E Terms of reference of the Joint Committee of the Regional Metro-logy Organizations and the BIPM (JCRB). Glossary of terms used in this arrangement BIPM:Bureau International des Poids et Mesures. CGPM:General Conference of Weights and Measures. CIPM:International Committee of Weights and Measures. Calibration and measurement capability:the highest level of cal-ibration or measurement normally offered to clients, expressedin terms of a confidence level of 95%, sometimes referred to asbest measurement capability. Calibration or measurement certificate: a certificate issued bya national metrology institute and relating to a test, calibrat-ion or measurement of an instrument or a reference material (pe-rtaining either to physical or to chemical measurements). CIPM key comparison: a key comparison executed by a ConsultativeCommittee or the BIPM leading to a key comparison reference val-ue. Degree of equivalence of a measurement standard: the degree towhich the value fo a measurement standard is consistent with thekey comparison reference value. This is expressed quantitativelyby the deviation from the key comparison reference value and theuncertainty of this deviation. The degree of equivalence betweentwo measurement standards is expressed as the difference betweentheir respective deviations from the key comparison reference v-alue and the uncertainty of this difference. Key comparison: one of the set of comparisons selected by a Con-sultative Committee to test the principal techniques and methodsin the field (note that key comparisons may include comparisonsof representations of multiples and sub-multiples of SI base andderived units and comparisons of artefacts). Key comparison database: the database maintained by the BIPM wh-ich contains Appendices A, B, C and D of this Mutual RecognitionArrangement. Key comparison reference value: the reference value accompaniedby its uncertainty resulting from a CIPM key comparison. National metrology institute: the national metrology institutesignatory to this arrangement is the metrology institute design-ated by the appropriate national governmental or other officialauthority as that responsible for national measurement standard-s. RMO key comparison: a key comparison executed by an RMO. Note:only key comparisons carried out by a Consultative Committee orthe BIPM lead to a key comparison reference value. For a key co-mparison carried out by a regional metrology organization the l-ink to the key comparison reference value is obtained by refere-nce to the results from those institutes which have also takenpart in CiPM key comparison. Supplementary comparison: comparisons carried out by the Consul-tative Committees, the RMOs and the BIPM to meet specific needsnot covered by key comparisons, including comparisons to supportconfidence in calibration and measurement certificates. Appendix E Terms of reference of the joint Committee of the Regional Metro-logy Organizations (RMOs) and the BIPM. 1 The joint Committee is charged with a) Coordinating the activities among the RMOs in establishingconfidence for the recognition of calibration and measurem-ent cerificates, according to the terms of the Mutual Reco-gnition Arrangement (MRA); b) making policy suggestions to the RMOs and to the CIPM on t-he operation of the MRA; c) analysing the application by each RMO of the criteria of t-he MRA; d) analysing and entering into Appendix Cthe proposals of eachRMO in respect of the calibration and measurement capabili-ties of their member NMIs and reporting to the CIPM; e) facilitating appropriate inter-regional supplementary comp-arisons; f) writing an annual report on the activities of the Joint Co-mmittee to the CIPM and to the signatories of the MRA. 2 Membership and meetings of the joint Committee a) each RMO informs the Director of the BIPM of the name of i-ts official representative on the Joint Committee; b) at each meeting of the Joint Committee the representativesmay be accompanied by appropriate advisors; c) the Joint Committee operates by consensus; d) the Joint Committee should meet at least once a year. |
