International Cooperation



The International Bureau of Weights and Measures (BIPM) is the organization established by the Metre Convention, through which Member States act together on matters related to measurement science and measurement standards. BIPM manages the official system for the demonstration of the equivalence of SI realization at the highest level through an International Arrangement established in 1999 by the International Committee of Weights and Measures (CIPM) and entitled as the Mutual Recognition Arrangement of national measurement standards and of calibration certificates issued by National Metrology Institutes (CIPM MRA).

The signing of this Arrangement facilitates the demonstration of measurement capabilities, contributes to reducing technical barriers to trade generated by measurement results, and offers metrological support for the development of the national economy by:

  • Mutual recognition of national measurement standards and calibration certificates issued by INM (CIPM MRA);
  • Publishing of key comparison results in which INM participates (KCBD);
  • Publishing of INM measurement capabilities (CMCs) on the BIPM website.

The Republic of Moldova adhered to the General Conference of Weights and Measures (CGPM) of the International Metrology Organization "Metre Convention" as an Associate Member in 2005.




The International Atomic Energy Agency in 1976, in collaboration with the World Health Organization, established an IAEA/WHO SSDL Network, and by fulfilling the obligations set for network members, a secondary standards dosimetry lab is receiving a range of benefits and access to a database that will make a significant contribution to its development.

The IAEA / WHO SSDL is an association of national SSDLs that have agreed to cooperate to promote the objectives of that network under international auspices. Its objectives are:

·  Accuracy: to provide dosimetry services and create and distribute knowledge in radiation dosimetry in order to improve the accuracy level in dose measurements;

· Traceability: to establish and facilitate links between end users of dosimeters, the SSDL members and the SI system for radiation measurements;

· Consistency: to promote international recommendations on methods applied for calibration and performance of dosimetry in order to achieve consistency of measurements in all countries;

  • Cooperation: to promote further the exchange of experience between the members and the metrology community, and to provide support to each other where necessary.



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 International Organization of Legal Metrology operates with the OIML Mutual Acceptance Agreement (OIML MAA), which establishes the mutual confidence in the measuring instruments assessment by its signatories and the mutual acceptance of the assessment results. 

The Republic of Moldova is a Corresponding Member of OIML since 1995.

Bilateral Cooperation

In order to ensure the experience exchange and the undertaking of best practices in the field, INM is cooperating with national metrology institutes of other states, by means of bilateral agreements. 

The bilateral agreements signed by INM focus on the following subjects:

  • cooperation in the research of primary measurements standards of institutes through bilateral interlaboratory comparisons, as well as in the area of measurement theory and techniques;
  • cooperation in the development of calibration procedures and measurement uncertainty estimation in various measurement fields;
  • cooperation in the training of staff through mutual internships; 
  • cooperation in the area of type approval of measuring instruments by means of experience exchange;
  • cooperation in the development of testing/research procedures for the measuring instruments used in various measurement areas.
  • experience exchange and trainings in the field of quality management systems.

Currently, INM has signed Cooperation Agreements and Memorandums of Understanding with the following institutions:

  • Romanian Legal Metrology Bureau (BRML)
  • National Institute of Metrology (INM) of Romania
  • Belarus Metrology Institute (БелГИМ)
  • Czech Metrology Institute (CMI)
  • Technological and Scientific Research Council (TUBITAK) of Turkey
  • Central Measurement Office of Poland (GUM)
  • Bosnia and Herzegovina Metrology Institute (IMBIH)
  • National Scientific Center „Institute of Metrology” of Harkov
  • National Metrology Institute (UzNIM) of Uzbekistan
  • National Standards and Metrology Agency (GEOSTM) of Georgia
  • National Scientific Center for Standardization, Metrology, Certification and Consumer Protection (Ukrmetrteststandart) of the Ukraine
  • Center for Physical Sciences and Technology (FTMC) of Lithuania.
Regional Cooperation



EURAMET is the Regional Metrology Organization of Europe.

EURAMET coordinates the cooperation of National Metrology Institutes (NMIs) in Europe in fields such as research in metrology, traceability of measurements to the SI units, international recognition of national measurement standards and related Calibration and Measurement Capabilities (CMC).

EURAMET was created on 11 January 2007 in Berlin. Legally, it is an organization registered according to the German legislation with headquarters in Braunschweig, and on 1 July 2007 it undertook the roles of EUROMET (EUROMET – European cooperation in the field of measurement standards, founded in Madrid, Spain on 23 September 1987, becoming operational on 1 January 1988) as Regional Metrology Organization.

The Republic of Moldova became an Associated Member of EURAMET in 2017 and a Full Member in 2019.




WELMEC represents the European Cooperation in Legal Metrology. Its members are national authorities responsible for legal metrology in the European Union member states and thode of the European Free Trade Association (EFTA).

WELMEC was created by means of a Memorandum of Understanding signed at a meeting that took place at Bern in June 1990. Eighteen countries of the European Community and of EFTA signed the initial Memorandum, which established the objectives and tasks of WELMEC and set the rights and obligations of its members. 

WELMEC objectives

  • Consolidation of mutual confidence in legal metrology services;
  • Harmonization of legal metrology activities;
  • Identification of legal metrology special characteristics to be reflected within the European metrology, certification and testing frammework;
  • Organization of the informational exchange;
  • Promotion of reducing technical barriers to trade related to measuring instruments;
  • Promotion of continuous interpretation and application of normative documents and proposal of actions for facilitating their implementation;
  • Identification of technical issues that could be subject of cooperation projects;
  • Maintenance of working relations with relevant bodies in the area of legal metrology;
  • Debating of tendencies and establishment of criteria for the legal metrology scope and maintenance of continuous knowledge transfer channels.

The Republic of Moldova is an Associated Member of WELMEC since 2017.




COOMET is the organization for the cooperation of national metrology institutes of the East and Central European countries, which was created in June 1991. In May 2000 the organization was renamed as the „Euro-Asian Cooperation of National Metrology Institutes”. Currently, the following states are COOMET members: Azerbaijan, Armenia, Belarus, Bulgaria, Germany (Associate Member), Georgia, Kazakhstan, Kyrgyzstan, Popular Republic of North Korea (Associate Member), Cuba (Associate Member), Lithuania, Republic of Moldova, Russian Federation, Romania, Slovakia, Tajikistan, Uzbekistan and the Ukraine.
The main activity of COOMET represents the cooperation on the following directions: physical quantities measurement standards, legal metrology, accreditation and quality management systems, information and training.

The Republic of Moldova is a Full Member of the Regional Metrology Organization COOMET since1997.
