BIPM : Bureau International des Poids et Mesures

The intergovernmental organization through which Member States act together on matters related to measurement science and measurement standards

The unique role of the BIPM enables it to achieve its mission by developing the technical and organizational infrastructure of the International System of Units (SI) as the basis for the world-wide traceability of measurement results. This is achieved both through technical activities in its laboratories and through international coordination.


  • To establish and maintain appropriate reference standards for use as the basis of a limited number of key international comparisons at the highest level.
  • To coordinate international comparisons of national measurement standards through the Consultative Committees of the CIPM; taking the role of coordinating laboratory for selected comparisons of the highest priority and undertaking the scientific work necessary to enable this to be done.
  • To provide selected calibrations for Member States.
  • To coordinate activities between the NMIs, such as through the CIPM MRA1, and to provide technical services to support them. To liaise as required with relevant intergovernmental organizations2 and other international bodies3 both directly and through joint committees4.
  • To organize scientific meetings to identify future developments in the world-wide measurement system required to meet existing and future measurement needs in industry, science and society.
  • To inform, through publications and meetings, the science community, the wider scientific public and decision makers on matters related to metrology and its benefits.

IAF : International Accreditation Forum

The IAF is the world association of Conformity Assessment Accreditation Bodies and other bodies interested in conformity assessment in the fields of management systems, products, services, personnel and other similar programmes of conformity assessment. Its primary function is to develop a single worldwide program of conformity assessment which reduces risk for business and its customers by assuring them that accredited certificates may be relied upon. Accreditation assures users of the competence and impartiality of the body accredited.

The primary purpose of IAF is two-fold. Firstly, to ensure that its accreditation body members only accredit bodies that are competent to do the work they undertake and are not subject to conflicts of interest. The second purpose of the IAF is to establish mutual recognition arrangements, known as Multilateral Recognition Arrangements (MLA), between its accreditation body members which reduces risk to business and its customers by ensuring that an accredited certificate may be relied upon anywhere in the world.

The MLA contributes to the freedom of world trade by eliminating technical barriers to trade. IAF works to find the most effective way of achieving a single system that will allow companies with an accredited conformity assessment certificate in one part of the world, to have that certificate recognised elsewhere in the world.
The objective of the MLA is that it will cover all accreditation bodies in all countries in the world, thus eliminating the need for suppliers of products or services to be certified in each country where they sell their products or services. Certified once - accepted everywhere.

ILAC : International Laboratory Accreditation Cooperation

Accredited once, accepted everywhere

ILAC is the international organisation for accreditation bodies operating in accordance with ISO/IEC 17011 and involved in the accreditation of conformity assessment bodies including calibration laboratories (using ISO/IEC 17025), testing laboratories (using ISO/IEC 17025), medical testing laboratories (using ISO 15189) and inspection bodies (using ISO/IEC 17020).

Accreditation bodies that are signatories to the ILAC Mutual Recognition Arrangement (ILAC MRA) have been peer evaluated as competent to assess and accredit conformity assessment bodies to the relevant internatinal standards. The results from the laboratories and inspection bodies accredited by the ILAC MRA signatories are then able to be recognised internationally.

The ILAC MRA provides significant technical underpinning to the results of the accredited conformity assessment bodies and in turn delivers confidence in the acceptance of results. The ILAC MRA supports the provision of local and national services, such as providing safe food and clean drinking water, providing energy, delivering health and social care or maintaining an unpolluted environment. In addition, the ILAC MRA enhances the acceptance of products across national borders. By removing the need for additional calibration, testing, medical testing and/or inspection of imports and exports, technical barriers to trade are reduced. In this way the ILAC MRA promotes international trade and the free-trade goal of “accredited once, accepted everywhere” can be realised.

IEC : International Electrotechnical Commission

Making electrotechnology work for you

Millions of devices that contain electronics, and use or produce electricity, rely on IEC International Standards and Conformity Assessment Systems to perform, fit and work safely together.

Founded in 1906, the IEC (International Electrotechnical Commission) is the world’s leading organization for the preparation and publication of International Standards for all electrical, electronic and related technologies. These are known collectively as “electrotechnology”.

IEC provides a platform to companies, industries and governments for meeting, discussing and developing the International Standards they require.

All IEC International Standards are fully consensus-based and represent the needs of key stakeholders of every nation participating in IEC work. Every member country, no matter how large or small, has one vote and a say in what goes into an IEC International Standard.

Close to 20 000 experts from industry, commerce, government, test and research labs, academia and consumer groups participate in IEC Standardization work.

IEC complements its standards development activities with international conformity assessment activities and thus creates greater value.

IEC operates four global conformity assessment (CA) Systems, IECEE, IECEx, IECQ and IECRE, each with participating testing laboratories and certification bodies from all over the world. Harmonised and documented operational and testing procedures combined with common interpretation of the international standards, then using peer assessment to ensure that the harmonised procedures and common interpretation are applied, ensures consistent and reproducible results from anywhere in the world. This is part of the value proposition offered by IEC global CA services, and is central to the success of the multilateral mutual recognition agreement that guarantees market access.

OIML : Organisation Internationale de Métrologie Légale

Paving the way towards a global metrology system since 1955

The International Organization of Legal Metrology is an intergovernmental treaty organization which

  • develops model regulations, standards and related documents for use by legal metrology authorities and industry,
  • provides mutual recognition systems which reduce trade barriers and costs in a global market
  • represents the interests of the legal metrology community within international organizations and forums concerned with metrology, standardization, testing, certification and accreditation
  • promotes and facilitates the exchange of knowledge and competencies within the legal metrology community worldwide
  • cooperates with other metrology bodies to raise awareness of the contribution that a sound legal metrology infrastructure can make to a modern economy

The OIML issues several categories of publications:

  • International Recommendations, which are intended as model regulations for a number of categories of measuring instruments, and which OIML Member States are morally obliged to implement as far as possible
  • International Documents, which are informative and are intended for guidance purposes
  • other publications such as Vocabularies, Guides, Basic Publications and Expert Reports.

In addition, the OIML has developed the OIML Certification System (OIML-CS) which is a system for issuing, registering and using OIML Certificates and their associated OIML type evaluation reports for types of measuring instruments (including families of measuring instruments, modules, or families of modules), based on the requirements of OIML Recommendations. In the OIML-CS participants declare that they intend to accept and utilize OIML Certificates and/or OIML type evaluation reports from those participants that are entitled to issue them. The OIML-CS was launched on 1 January 2018, replacing the previous OIML Basic Certificate System and the OIML Mutual Acceptance Arrangement (MAA).

UNIDO : United Nations International Development Organisation

UNIDO is the specialized agency of the United Nations that promotes industrial development for poverty reduction, inclusive globalization and environmental sustainability. UNIDO’s vision is of a world where economic development is inclusive and sustainable and economic progress is equitable. UNIDO aspires to reduce poverty through inclusive and sustainable industrial development (ISID).

UNIDO’s mandate is fully recognized in SDG-9, which calls to “Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation”. The relevance of ISID, however, applies in greater or lesser extent to all SDGs. All countries should have the opportunity to grow a flourishing productive sector, to increase their participation in international trade and to safeguard their environment. Accordingly, the Organization’s programmatic focus is structured in three thematic priorities, each of which represents different aspects of ISID:

  • Creating shared prosperity
  • Advancing economic competitiveness
  • Safeguarding the environment

UNIDO has developed a comprehensive programme to help developing countries and economies in transition to overcome the shortcomings of their standards and compliance requirements. UNIDO’s assistance in the area of metrology, accreditation, standards and conformity assessment aims to:

  • Enable national standards bodies to offer services for industrial compliance with WTO agreements, especially on TBT/SPS, while taking into account private sector, exporter and consumer needs
  • Develop local capacities in metrology, calibration and product testing, in order to provide services to local testers, producers and exporters according to international best practices, and also to enhance consumer protection
  • Make internationally recognized certification services for international public and private standards regarding, inter alia, quality, environment, social accountability, food safety, and traceability, available to exporters and local enterprises
  • Enable national and regional accreditation schemes to assess the performance of local and regional laboratories, inspection units and certification bodies; and
  • Build the capacities of consumer associations to promote consumer rights based on national policies and in line with international best practices.

In carrying out the core requirements of its mission, UNIDO has proven its worth for diverse customers in different business sectors in Africa, Asia, Middle East and Latin America. Its technical services have considerably increased over time. At the same time, it has also substantially increased its mobilization of financial resources, testifying to the growing international recognition as an effective provider of catalytic industrial development services.
