1 Internationally accepted framework for metrology Andy Henson BIPM

2 Working Groups The BIPM Bureau International des Poids et Measures the intergovernmental organization through which Member States act together on matters related to measurement science and measurement. Established in 1875 when 17 States signed the Metre Convention. Currently there are 58 Member States of the BIPM, and 41 Associates of the General Conference. CGPM Conférence Générale des Poids et Mesures Official representatives of Member States. CIPM Comité International des Poids et Mesures Eighteen individuals of different nationalities elected by the CGPM. BIPM Bureau International des Poids and Mesures representing the worldwide measurement community centre for scientific and technical collaboration coordinator of the worldwide measurement system Consultative Committees (CCs) CCAUV Acoustics, US & Vibration CCEM Electricity & Magnetism CCL Length CCM Mass and related CCPR Photometry & Radiometry CCQM Amount of substance CCRI Ionizing Radiation CCT Thermometry CCTF Time & Frequency CCU - Units Membership of the BIPM provides states with the opportunity To gain global recognition and acceptance for measurement capabilities (CIPM MRA) To participate in the structures that support and develop the SI To be active in scientific and technical forums that support the development of measurement capability 2

3 Global Quality Infrastructure National Standards Body certification body required for certification accreditation body certification bodies certification inspection body National Accreditation Body inspection bodies definition of units (as required in ) inspection certificate testing laboratory ENTERPRISES testing laboratories test report National Metrology Institute calibration certificate required for laboratory accreditation calibration laboratory calibration laboratories calibration certificate Enhanced product quality and compatibility Enhanced safety and health Decreased environmental impact Increased trade opportunities Facilitating innovations to the market place Metrology is a key part of the global quality infrastructure that underpins world trade. The work of the NMIs is made visible and transparent through the CIPM-MRA signed in 1999, which, provides the technical basis for the worldwide acceptance of national measurement and calibration and measurement certificates from NMIs. BENEFITS Source: World Bank AUTHORITIES, CONSUMERS, AND GENERAL PUBLIC The work of the CIPM MRA now goes far beyond matters of trade to cover climate change, healthcare etc. 3

4 The CIPM Mutual Recognition Arrangement Objectives: to establish the degree of equivalence of national measurement maintained by NMIs to provide for the mutual recognition of calibration and measurement certificates issued by NMIs Participation 98 National Metrology Institutes 57 Member States 41 Associates 4 International organizations (ESA, IAEA, IRMM, WMO) plus 156 Designated Institutes Total: 258 Institutes Science based, peer reviewed, public data 4

6 Joint BIPM, OIML, ILAC and ISO declaration on measurement traceability The BIPM, OIML, ILAC, and ISO endorse the following recommendations: in order to be able to rely on their international acceptability, calibrations should be performed in National Metrology Institutes who should normally be signatories to the CIPM MRA and have CMCs published in the relevant areas of the KCDB or in laboratories accredited by accreditation bodies which are signatories to the ILAC Arrangement; measurement uncertainty should follow the principles established in the GUM; the results of the measurements made in accredited laboratories should be traceable to the SI; NMIs providing traceability for accredited laboratories should normally be signatories to the CIPM MRA and have CMCs published in the relevant areas of the KCDB; within the OIML s MAA, accreditation should be provided by bodies which are signatories to the ILAC Arrangement and the above policies on traceability to the SI should be followed; The above principles should be used whenever there is a need to demonstrate metrological traceability for international acceptability. Use of this Declaration These principles underpin a world measurement system which provides a robust, internationally accepted framework within which users can have confidence in the validity and acceptability of measurements results. BIPM, OIML, ILAC and ISO strongly urge legislators and regulators to refer to the Arrangements described earlier in this Declaration and also to accept measurement results made within this system, thereby helping avoid technical barriers to trade. We also invite interested parties to endorse these principles and to make use of them in their own work. Option 1) from ILAC P10:01/2013 An NMI whose service is suitable for the intended need and is covered by the CIPM MRA. Services covered by the CIPM MRA can be viewed in Appendix C of the BIPM KCDB which includes the range and uncertainty for each listed service. Traceability can be taken directly from the NMIs, but often is implicit by calling up accredited laboratory services ( 6
