As an institution that is part of the quality infrastructure of the Republic of North Macedonia, Bureau of Metrology is directly involved in the implementation of the legislation in the area of metrology, which, beside the national one, covers the regulation from the new and harmonized approach in the field of metrology.

In accordance with the legal framework, laid down in the Law on Metrology, Bureau of metrology (BoM) is the National Metrology Institute (NMI) and national authority responsible for development and maintenance of the metrology system in the Republic of North Macedonia.

Bureau of metrology, as an authority within the Ministry of economy, is responsible institution for implementation of the:

  • Law on metrology
  • Law on control of precious metals articles
  • Law on vehicles - authority for administrative approval in the procedure of homologation of vehicles

The role of Bureau of metrology as NMI is development and maintenance of national measuring standards, ensuring traceability to the international level and dissemination of units. As legal metrology authority, BoM is responsible for ensuring adequate metrological control (conformity assessment, placing on the market and putting into use, periodic and after repair verification) of measuring instruments. Verification of measuring instruments is performed by BoM.

Bureau of Metrology cooperates with regional and international organizations in the field of metrology. Bom is member of EURAMET, associate member of WELMEC and BIPM, member of OIML and IAAO and is a signatory of the CIPM MRA since 2007.

The role of Bureau of metrology is to ensure adequate metrological control (conformity assessment, placing on the market and putting into service, periodic and after service verification) of measuring instruments, which include the instruments covered by Measuring Instruments Directive (MID) and Directive for Non-automatic Weighing Instruments (NAWI), but also measuring instruments that are subject to national regulation. 

The list below contains information for the types  of measuring which are subject to legal metrolog

    • Measuring instruments for resistance (earth resistance, insulation resistance)
  • Other
    • Lux-meters
    • Measuring instruments for speed of vehicles
    • Taximeters
    • Heat meters

Most of the measuring instruments listed above are subject to type approval. 

National type approval responsibility rests with BoM for all measuring instruments subject to Legal Metrology. BoM may use other test laboratories which comply with the requirements of ISO/IEC 17025 standard. Fees and costs for issuing a type approval certificate or performing a conformity evaluation and verification are defined in Government Ordinance. According to the national legislation, BoM recognizes EC Type Approvals of measuring instrument, which have been lawfully produced and marketed in one of the EU Member States. For all the measuring instruments which are subject of legal metrology (harmonized area and national legislation), BoM maintains Register of measuring instruments.

Before putting into use, measuring instruments are subject of initial verification. Periodical verification is performed to measuring instruments in service, in time intervals determined in the Rulebook, adopted by the Minister of economy.

Verification of measuring instruments is be carried out by BoM. BoM also cooperates with accredited inspection bodies which are responsible for preparing measuring instruments for verification.

Typical intervals for re-verification in accordance to the Rulebook:

  • Weighing instruments: 1 – 2 years
  • Water meters: 5 years
  • Fuel dispensers: 1 year
  • Electricity meters: 10 years

Extraordinary / After repair verification is performed in cases when the measuring instruments are repaired and the re-verification period is exceeded (measuring instrument put out of use for certain period of time).  Extraordinary / After repair verification is performed after the authorized service companies have submitted evidence that all necessary elements laid down in the particular legislation are fulfilled. 

Market surveillance of measuring instruments on the phase after placing on the market and phase of use is performed by State Market inspectorate. Metrological supervision of measuring instruments in usage and their users as well as authorized legal entities is performed by BoM.  BoM practices random programme for metrological supervision of measuring instruments in use.

BoM at present has 40 employees. Most of the employees involved in the legal metrology activities are with a technical background – engineers and technicians.

Sanctions are based upon a system of administrative penalties. A preventive enforcement policy is applied resulting in penalties normally only being applied in cases where fraud is evident. Non-verified measuring instruments, if used, can be impounded or sealed to prevent further use. Instruments that exceed the MPE will be prohibited from further use and may be sealed.
