Country Information Montenegro

Montenegro is located in the South-East Europe covering an area of 13,812 square kilometers. Podgorica is the capital, a political, commercial and cultural center. Old Royal Capital town is Cetinje. Montenegro has a population of nearly 630,000.

According to the Constitution of Montenegro (“Official Gazette of MNE” 01/07) Montenegro is a civic state of the republican form of government, a social and ecological state. Montenegro is a country of parliamentary democracy, a state of balanced parliamentarism and the division of power into the legislative, executive and judicial.

The President of Montenegro is elected by a direct and general election. The legislative power rests with National Assembly. The government is the highest executive body and is answerable to the National Assembly.

The Government of Montenegro founded the Bureau of Metrology on September 14, 2006. The Bureau is composed of the following 5 units: Department for Metrological Traceability and National Standards, Department for Verification of Measuring Instruments, Section for Precious Metals, Section for International Cooperation and Service for General Affairs and Finance. The Bureau performs activities in the field of legal, scientific and industrial metrology, as well the control of precious metal articles, and performs the duties of the National Metrology Institute (NMI) in Montenegro.

The Bureau of Metrology performs activities related to: ensuring application of the system of legal units of measurement; realization, keeping, maintaining and improving the measurement standards of Montenegro; ensuring metrological traceability for calibration laboratories, as well as for testing and control laboratories; organization of calibration activities; assessment of conformity of measuring instruments with metrological requirements; provision of expert opinion concerning authorization of laboratories for preparation of measuring instruments for verification; representation of Montenegro in international and regional metrological organizations and establishment of cooperation in the field of metrology; control of precious metal articles, as well as other affairs falling within its competence.

Accreditation Body of Montenegro and Croatian Accreditation Agency have confirmed that the Bureau of Metrology fulfills the requirements of MEST EN ISO/IEC 17025:2018 – General requirements for the competence of testing and calibration laboratories and that it is competent to carry out calibration of: weights, weights with free nominal masses and non-automatic weighing instruments, laboratory glassware and piston-operated volumetric apparatus, etalons of overflow pipettes and standard capacity measures; temperature and relative humidity gauges, standards and instruments for measurement of length, standards and instruments for measurement of electrical quantities, frequency and time interval, pressure gauges, and instruments for measurement of ionizing radiation. The confirmed competence enables the Bureau to provide its services with regard to calibration of measuring instruments/measurement standards to non-Montenegrin clients as well.

In July 2016, the Bureau of Metrology obtained license for performing scientific-research activities in the field of technical-technological and interdisciplinary sciences.

The Bureau of Metrology represents Montenegro in international and regional metrology organizations. Montenegro became an associate member of the CGPM - General Conference on Weights and Measures on 1 August 2011. This membership was a prelude to the signing of the CIPM MRA (CIPM Mutual Recognition Arrangement) on 19 October 2011.

The Bureau of Metrology has been a full member of the European Association of National Metrology Institutes (EURAMET) since 2011. The Bureau has participated in EURAMET's Technical Committees in the field of Electricity and Magnetism, Interdisciplinary Metrology, Flow, Mass and Related Quantities, Quality, Thermometry, Length, and Time and Frequency.

The Bureau of Metrology has been a corresponding member of International Organization of Legal Metrology (OIML) since November 2007.

Based on the invitation extended to the Bureau of Metrology by the BIPM to accede to the Metre Convention, the Bureau has prepared expert grounds for the Proposal for the Law on Ratification of the Metre Convention, adopted towards the end of 2017. The accession process was finalized in January 2018, Montenegro and the Bureau of Metrology, as the National Metrology Institute, were granted a full membership in the International Bureau of Weights and Measures (BIPM) on 24 January 2018.

In October 2020, the Bureau of Metrology acquired the status of observer in the Convention on Control and Hallmarking of Precious Metal Articles –Hallmarking convention.

According to the Law on Metrology (Official Gazette of Montenegro 79/08 and 40/11), the Bureau is so far the only subject of metrology infrastructure in Montenegro responsible for verification of legal metrology instruments. Legal measuring instruments which are subject to mandatory verification or type approval are classified into four categories as follows:

  • Measuring instruments used in trade of goods and services and control of pre-packaged products and measuring container bottles
  • Measuring instruments used in protection of human and animal health and general safety
  • Measuring instruments used in protection of assets, environment and natural resources, occupational safety and accident prevention
  • Measuring instruments used in traffic safety

The Bureau of Metrology at present has 44 employees, and 2 interns with fixed-term contracts, one for a period of six months, and one for a year. The employees engaged in type approvals and verification procedures are mainly engineers. They are mainly trained on the job.

Sanctions are based upon a system of administrative penalties. A preventive enforcement policy is applied resulting in penalties normally only applied in cases where fraud is evident. Depending on the type of violation, the fines will be imposed as follows:
