The Bureau of Metrology is a public body, founded on September 14, 2006. It performs activities in the field of legal, scientific and industrial metrology, and performs the duties of the National Metrology Institute (NMI) in Montenegro.

The Bureau has been recognized as competent for carrying out calibrations by the Accreditation Body of Montenegro (ATCG) and Croatian Accreditation Agency (HAA), which have confirmed that it fulfils the requirements of the MEST EN ISO/IEC 17025:2011 standard – General requirements for the competence of testing and calibration laboratories, thus ensuring accurate measurement results traceable to the international standards.

As prescribed by the Decree on Organization and Method of Operation of State Administration, the Bureau of Metrology performs affairs 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 related activities; assessment of conformity of measuring instruments with metrological requirements; provision of expert opinion concerning authorization of laboratories for verification of measuring instruments; control of precious metal articles, as well as other affairs falling within its competence.

The Bureau also represents Montenegro in regional and international organizations: EURAMET – full membership, OIML – corresponding member, WELMEC – associate member and member of IAAO. Represented by the Bureau of Metrology, Montenegro joined the International Bureau of Weights and Measures (BIPM) at the beginning of 2018, as the 59th member of this organization.

In July 2016, the Bureau of Metrology obtained a license for performing scientific-research activities in the field of technical-technological and interdisciplinary sciences. The Bureau of Metrology has been registered in the Registry of Innovative Organizations since October 2018. From the moment of acquiring the status of a scientific-research institution (2016), the Bureau of Metrology has intensified its activities related to the strengthening of its scientific and research capacities and participation in projects.

In addition to projects dealing with the development of the metrology system in Montenegro, the Bureau has also been very active when it comes to organizing activities aimed at raising awareness of the importance of metrology and educating the younger population on the basic concepts of measurement. Some of these are: the “Open Days” – organized in May every year to mark the World Metrology Day (20 May), the contest called the “Beauty of Crystals” in which elementary and secondary school students had an opportunity to grow inorganic and organic salt crystals, knowledge quiz called „Why are measurements important?“ for students of elementary schools and others.

Metrologija je osnov svih naučnih istraživanja. Upravo zbog toga Zavod za metrologiju može svojim učešćem u projektima pružiti značajan doprinos u mnogim oblastima u okviru programa bilateralne, prekogranične i transnacionalne saradnje. Projektni tim Zavoda za metrologiju, sastavljen od predstavnika svih organizacionih jedinica Zavoda, kontinuirano analizira potrebe i mogućnosti za unapređenje rada institucije kroz učešće u projektima lokalnog i međunarodnog karaktera. Osnovne aktivnosti ovog tima podrazumijevaju identifikovanje mogućnosti za učešće u projektima, umrežavanje sa potencijalnim partnerskim organizacijama, kao i samu pripremu i realizaciju projekata.

IPA 2007 and IPA 2011

Metrological traceability chain in the field of mass, length, temperature, pressure, volume, electrical quantities, as well as time and frequency in Montenegro is based on equipment provided by the Bureau of Metrology by participating in the projects “Development of Quality Infrastructure in Montenegro” (IPA 2007) and “Development of Quality Infrastructure and Metrology in Montenegro” (IPA 2011), as well as the equipment provided by the Bureau from its own resources.

IPA 2007

As part of the project “Development of Quality Infrastructure in Montenegro”, equipment worth € 950,000.00 has been allocated for the laboratories of the Bureau through the European Union’s Instrument for Pre-accession Assistance (IPA 2007). The aim of this project was to accelerate legal, regulatory and institutional reforms in the area of quality infrastructure in Montenegro in line with EU acquis and WTO membership requirements. In addition to the Bureau of Metrology, the beneficiaries of the project were the Accreditation Body of Montenegro, the Institute for Standardization of Montenegro and the Ministry of Economy.

IPA 2011

Within the project “Development of Quality Infrastructure and Metrology in Montenegro”, equipment in the value of € 600,000.00 has been allocated for the development of the Bureau’s laboratories through the European Union’s Instrument for Pre-accession Assistance (IPA 2011). The aim of this project was to facilitate trade and free movement of goods in accordance with EU and WTO requirements in Chapter 1 – Free movement of goods. In addition to the Bureau of Metrology, the beneficiaries of the project were the Ministry of Economy and the Agency for Medicines and Medical Devices of Montenegro (CALIMS).

The Bureau of Metrology participated as partner in the project entitled “MNE9004: Upgrading the national system for radon protection” funded by the International Atomic Energy Agency (IAEA). As part of the project, which began in January 2014, the Bureau received equipment for the first phase of the Laboratory for Ionising Radiation, which established conditions for the provision of calibration services for devices measuring radon concentration in air, both for clients from Montenegro and the needs of the neighbouring countries.

Equipment from IPA 2014 National Program Delivered

Valuable measuring equipment, for purchase of which the funds have been allocated from the IPA 2014 national program, was delivered to the Bureau of Metrology with the aim of improving the work process of Laboratory for Electrical Power, Laboratory for Electrical Quantities, Laboratory for Time and Frequency, Laboratory for Temperature, Laboratory for Testing of Pre-Packaged Products, and the Laboratory for Precious Metals.

The Bureau of Metrology is one of the beneficiary institutions in the project in the IPA 2014 program “Supply of equipment to specialized institutions of Montenegro for EU Internal Market Acquis implementation, which was predicted by the Program of Accession of Montenegro to the EU 2018 – 2020 (PPCG).

With the purchased equipment, the Bureau will improve its technical competence and capacities, work procedures, i.e. the field of calibration, verification of the measuring instruments, and control of the precious metal articles, which will enable further development of a modern system in Montenegro.

The use of the new equipment will be another confirmation that the Bureau of Metrology, with the quality of its services, provides security and confidence in the measuring system in Montenegro. The acquired equipment will enable further process of development of the national metrological institute which establishes, preserves, maintains, and improves the national measurement standards and provides metrological traceability in Montenegro.

Laboratory for Electrical Quantities

A portable precise multimeter, type 8104, manufactured by Transmille, was delivered to the Laboratory for Electrical Quantities. With its 8.5-digit resolution it belongs to the group of high-precision multimeters. With the said purchase, conditions for the portable high-precision multimeter to be used as a national measurement standard in order to perform calibration of clients’ measuring instruments, in one segment of measurements, will be created in the Laboratory for Electrical Quantities.  By doing this, the national standard in the field of electrical quantities, the multimeter, type FLUKE 8508, which had the leading role of a national standard until now, will be somewhat unburdened. Also, a portable multifunctional calibrator, type 9041A, manufactured by Transmille, was delivered to the Laboratory for Electrical Quantities, and it represents the source of power, current and resistance. The new calibrator in the Laboratory will, in one segment of measurements, be used as a working standard, which will be used to calibrate measuring instruments of the Bureau of Metrology’s service users.

Considering that this is a mobile, i.e. portable calibrator, it also creates a possibility of performing calibrations on the field, i.e. in-situ.


Laboratory for Electrical Power

A system for examination of electricity meters was delivered to and installed in the Laboratory for Electrical Power. The system type is MTS 320, manufactured by the German company ZERA GmbH. The delivered system enables testing of active energy of accuracy class 0.2S, 0.5S, 1, 2, A, B, and C, and electricity meters of reactive energy of accuracy class 2 and 3. The system’s accuracy class is 0.008, and it also has the possibility of simultaneous testing of twenty electricity meters. This significantly increased the capacity of the Laboratory for Electrical Power of the Bureau of Metrology to, because, until now, it had the system with the ability to simultaneous test three electricity meters. As stated, the new system has twenty test positions, the first five of which are equipped for testing of SMART METERING type electricity meters. Since 2011, the Electric Power Company of Montenegro (EPCG) replaced almost every electricity meter of end users in Montenegro with the smart metering devices.

It is important to emphasize that the Bureau will, in the future, have the ability of examination and verification of these electricity meters, whose measuring accuracy can be doubted by an interested party, which is very important regarding protection of consumers’ rights.

By acquiring the new system, the Laboratory for Electrical Power has significantly improved its capacities, created higher-quality working conditions, and strengthened the position of the Bureau of Metrology in the metrological system of Montenegro.

Laboratory for Testing of Pre-Packaged Products

A non-automatic weighing instruments, model XPR80002S, manufactured by Mettler Toledo AG, with the maximum measuring range of max=8,100 g, accuracy class II, whose reading scale interval is d=0.01 g and testing scale interval e=0.004 g, with a corresponding printer, as well as a non-automatic weighing instruments, model XPR16001L, also manufactured by Mettler Toledo AG, with the maximum measuring range of max=16,100 g, accuracy class II, whose reading scale interval is d=0. 1 g and testing scale interval e=0.08 g, with a printer and a corresponding portable case were delivered to the Laboratory for Testing of Pre-Packaged Products.

The precise weighing instruments, manufactured by Mettler Toledo AG, enable accurate measurement results and guarantee that measurement results are always reliable and that they meet even the strictest regulations of pre-packaged products control. Considering that a pre-packaged product is a combination of product and individual packaging of the product, it is important to accurately and reliably determine the actual quantity, i.e. the mass of the pre-packaged product. The actual quantity is documented by measurement results or verification based on mass or volume of sampled pre-packaged products.

The Laboratory for Pre-Packaged Products also got a software for statistical control of prepackages, model FreeWeigh.NET Compact, manufactured by Mettler Toledo AG. The software enables faster and better quality control of prepackages.

A portable densitometer was also delivered, model Densito, manufactured by Mettler Toledo AG, of measuring range from 0 g/cm3 to 3 g/cm3, and resolution 0.0001 g/cm3. The portable densitometer enables reliable and precise measuring of density in the laboratory and on the field, with the measurement accuracy to the third decimal place. The densitometer has the storage capacity of 1,100 measurement results, including the ID of the sample, measuring unit, temperature correction coefficient, ID of the instrument, date and time. Using a portable densitometer, it is possible to quickly and efficiently see whether the obtained results of density measurements are within the expected limits.

In addition, cylindrical pycnometers made of borosilicate glass, manufactured by companies Witeg and Brand, of nominal volumes of 50 ml and 100 ml. The Laboratory for Pre-Packaged Products got metal pycnometers made of stainless steel, manufactured by TQC, of nominal values of 50ml and 100 ml. Cylindrical, glass and metal pycnometers are used to determine the liquid density, i.e. their specific weights, in the Laboratory for Pre-Packaged Products.

Installation and use of the equipment delivered within the IPA 2014 program widened the laboratory capacities. The delivery of the equipment opened the possibility for a more intensive cooperation with the Administration for Inspection Affairs, with the aim of providing adequate consumer protection and trust in nominal quantities of pre-packaged products.


Laboratory for Temperature

A maintenance bath for water triple point, with a temperature range of ± 0,01 °C do ± 0,03 °C, in-cell stability of ±0,001 °C, ±0,0001 °C, which require maintenance of external conditions from 18 °C to 28 °C, was delivered to the Laboratory for Temperature. Purchase of this equipment will significantly improve the work of the Laboratory, which used the Dewar flask to realize the triple point of water until now. The manufacturer of the said equipment is ISOTECH ITL-M.

Also, an instrument for monitoring and storing the values of environmental conditions, type 176 H1, manufactured by TESTO, was delivered to this Laboratory. The instrument is used for monitoring and storing temperature and relative humidity values in cases when calibration is performed on the field, i.e. at the user’s premises.

Except the mentioned, a portable humidity and temperature generator, type HydroGen 2, manufactured by Rotronic AG, was delivered to the Laboratory for Temperature. It is used as a thermostatically controlled medium during calibration of relative humidity and temperature measuring instruments.
A Dew Point meter was delivered, type 473-SH2, manufactured by MBW Calibration Ltd, which will be used as a working standard for calibration of relative humidity measuring instruments.

With the installation of the new equipment, the Laboratory for Temperature improved its capacities, which enables a better quality, faster and more efficient provision of services of calibrating relative humidity and temperature measuring instruments to its users. Part of the new equipment will enable larger capacity; to be more precise, with the current equipment, the laboratory will be able to perform a larger number of calibrations of both relative humidity measuring instruments and temperature measuring instruments.

The new equipment has better performance, so the improvement is also seen in the quality of services. Calibrations will be performed with greater accuracy and precision, which will contribute for the measured results to be given with a better measurement uncertainty. Also, less time will be necessary for a larger number of calibrations, than it was the case until now. Calibrations will be more precise and the measurement uncertainty will be better. The important thing is that use of the new equipment will reduce the possibility of non-compliant work caused by a possible equipment malfunction or by sending the equipment to an external calibration to foreign national metrology or designated metrology institutes.

As for the official beginning of use of the new equipment, we have to point out that the maintenance bath for triple point of water will be put into operation when the water triple point is realized in the laboratory. That way it will be possible to maintain the realization of the triple point of water up to two months. The triple point of water serves to check secondary and working standards for temperature. This will enable that working standards be checked longer before the beginning of calibration, all with the aim of ensuring quality of calibration results in the Laboratory for Temperature. With the portable humidity and temperature generator, it is important to evaluate the workspace first, and then it will be possible to perform calibrations of relative humidity and temperature measuring instruments in it with the Dew Point meter.

A device for monitoring the environmental conditions in case of calibrations performed on the field will be calibrated and used on the field as such after the delivery of missing sensors for temperature and relative humidity.


Laboratory for Time and Frequency  

Two NTP time servers LANTIME M900, manufactured by Meinberg, were delivered to the Laboratory for Time and Frequency. NTP server is a time server which can be used for synchronization of even the largest networks in computer centers, industrial network infrastructure and telecommunication environment. By using this server, synchronization of a large number of clocks in relation to given reference time can be performed. M900 is a system platform which can be adjusted to certain needs, because it offers a broad spectrum of possible configurations, including the choice for frequency inlets and outlets, as well as improvement of redundancy for the needs of error-free synchronization. Besides, it enables synchronization of NTP and SNTP compatible clients. The interface for the status and configuration is based on internet, and the service program for graphic configuration is based on a console. It supports the following network protocols: IPv4, IPv6, HTTPS, HTTP, SSH, TELNET, SCP, SFTP, FTP, SYSLOG, SNMP.

Installation of the mentioned NTP servers in the Laboratory for Time and Frequency presents a basic step in the process of time distribution which is realized by means of the national measurement standard for time and frequency (Microsemi 5071A Caesium clocks), meaning that this installation enabled synchronization of clients’ clocks in relation to time realized in the Bureau of Metrology. The Laboratory for Time and Frequency participates in the realization of the UTC time, but due to non-possession of the corresponding NTP servers, it was not possible for the Laboratory to distribute the realized exact time. Time servers for distribution can be public and with limited access.

Immediately after the installation, the Laboratory for Time and Frequency will be given the possibility of creating addresses for distribution of exact time via public server to users who don’t use time for business purposes and for further distribution. After regulating the legal framework for distribution of time on the territory of Montenegro, and after acquiring the necessary equipment, both by the Bureau of Metrology and end users, who will be legally obliged to synchronize their clocks in relation to Montenegrin time, it is considered that the mentioned servers will be of use for establishment of Montenegrin legal time distribution.
A frequency meter, type CNT-90, manufactured by Pendulum Instruments Sp. z o.o., was delivered to the Laboratory for Time and Frequency. The meter is used for measuring, analysis, and calibration of frequency, time or phase. It can be used in laboratories for calibration or for certain research and development.
By installing the Pendulum CNT-90 frequency meter, the Laboratory for Time and Frequency will get another working standard, which would be used to perform calibration of devices used for measuring frequency and time intervals. This would unburden the use of the existing frequency meter, because until now the laboratory had only one working frequency meter.

Installation of the mentioned equipment in the Laboratory for Time and Frequency will also meet one of the requirements of the MEST EN ISO/IEC 17025 standard, in order to provide the backup of working standards and avoid disruption of laboratory activities, if a malfunction occurs on any of the devices. The mentioned frequency meter is a high-performance device: it has up to 250,000 of measurements per second, with a resolution of 12 digits per second (for frequency), 100 ps (for time), 0.0010 (for phase), with a standard frequency range of 400 MHz, and optional frequency of 3, 8, 15, and 20 GHz, which will be very useful for activities which are realized in the Laboratory for Time and Frequency.

In addition, a study visit to institutions in Spain was realised, namely to the National Securities Market Commission (CNMV) based in Madrid and the Royal Institute and Observatory of the Navy (ROA) in Cadiz. During the study visit, representatives of the Bureau of Metrology and the Capital Market Commission were given an opportunity to get acquainted with the way institutions in Spain achieve time distribution.

EMPIR Research Mobility Grant – RMG

Under the European metrology programme for innovation and research (EMPIR), the research staff  working at the National Metrology Institutes are enabled to participate in Research Mobility Grants under projects funded through this program. The aim of these grants is to develop the capacity of the European research metrology community. The selected researchers spend one to eight months working on a Joint Research Project (JRP) in another member country of the European Association of National Metrology Institutes (EURAMET).

As part of the European Metrology Research Program (EMRP), during 2017, a representative of the Bureau of Metrology, Head of the Laboratory for Temperature, participated in the EMRP ENV58 MeteoMet 2 (Metrology for Essential Climate Variables) project through a Researcher Mobility Grant (RMG) . The representative stayed at the Italian National Metrology Institute INRiM from March 14, 2017 to June 30, 2017. The main objective of this project was a preliminary study on the effect of wind speed and the effect of radiation on the accuracy of measuring air temperature under different conditions for thermometers used in automatic weather stations.

From March 6 to May 28, 2017, an employee of the Bureau of Metrology participated in the JRP Project: ENG56 – “Traceable Measurement of Drive Train Components for Renewable Energy Systems” as a beneficiary of a research grant – RMG1 DriveTrain. The project was organized under the EMRP and implemented at the RWTH (Rheinisch-Westfalische Technische Hochshule) in Aachen, Germany. The research within the project concerned the determination of linear errors of coordinate measuring machines at different temperatures.

During 2019, EMPIR approved RMG grants to two staff members of the Laboratory for time and frequency. The approved grants – 17IND14-RMG2 and 17IND14-RMG3 are part of the project Precision Time for Industry (17IND14). The participants in this project are the National Metrology Institute of Italy (INRIM), France (LNE-SYRTE), the United Kingdom (NPL), Sweden (RISE) and the Netherlands (VSL). The project deals with the development of new technologies for the distribution of time for industrial purposes. The Bureau’s employees will do research into the application of White Rabbit (WR) time distribution technologies. A research visit for the Bureau’s employees is planned for the first and fourth quarters of 2020 at the National Institute of Metrological Research in Italy.

The Laboratory for Temperature at the Bureau of Metrology started participating as an external partner in the EMPIR project JRP r02 HUMEA: Expansion of European research capabilities in humidity measurement in June 2016. Organized by the EURAMET, EMPIR and NSAI (National Standards Authority of Ireland) in 2018, a partner meeting on was held in Dublin in 2018 within the EMPIR project Expansion of European research capabilities in humidity measurement.

In addition, a workshop entitled: “Improvements in the field of dew point temperature standards” under the project JRP r02 HUMEA: “Expansion of European research capabilities in humidity measurement” organised by the EURAMET, EMPIR and ČMI was held in Prague in December 2018. Two representatives of the Bureau’s Laboratory for Temperature attended this workshop.

The project ended in May 2019.

As part of the regional project SIDA – Quality Infrastructure in the Western Balkans, which aimed to strengthen the capacities of institutions for the economic integration into the European Union, training courses were organized in the field of legal metrology and calibration of measuring instruments/ measurement standards.

Metrology guide (.pdf)


During 2019, the Bureau of Metrology was the first state authority to test its work against the requirements of the CAF methodology, as part of a project jointly implemented by the Regional School of Public Administration (ReSPA) and the Center for Public Administration Research (KDZ- Austria). The goals of implementing the CAF system in institutions are: the professionalization of public administration, the introduction of principles of total quality management (TQM) in public administration, the progressive orientation towards a complete “plan-do-check-act” cycle, facilitating self-assessment in public organizations to identify improvement activities and facilitating „bench-learning“ between among public authorities.

The main steps of applying the CAF system are as follows:

  • Customizing CAF questionnaires to the individual needs of the organization;
  • Training of the self-assessment team;
  • Constant monitoring of the entire CAF process;
  • CAF self-assessment workshop;
  • Consolidated self-assessment workshop report with improvement measures;
  • Development of a CAF action plan;
  • Knowledge base.

Under the CAF framework, a self-assesment team was formed at the Bureau of Metrology,, composed of representatives of all levels of employees, including senior management. Based on the Self-Assessment Report, a list of proposed improvement actions was analyzed and a list of “Quick Wins” was created. The main activity of the CAF methodology was the creation of an Action Plan for the implementation of the CAF activities at the Bureau of Metrology. This model envisages that the defined actions be applied in the next two years in order to improve the overall work of the Bureau of Metrology.
