Serbia

Republic of Serbia is a democratic state with the population of 7.5 million. Belgrade with a population of 1.6 million is capital and administrative, economic and cultural centre. The Republic of Serbia is divided into 29 districts. The country covers a land area of 88,361 km2.

President of the Republic is elected by a direct and general election. Legislative power rests with the unicameral National Assembly. Deputies in National Assembly elect Government, which, together with President of the Republic, represents the country's executive authority. The judiciary is independent. Supreme Court of Serbia decides on legal remedies instituted against decisions of all courts in the Republic of Serbia.

Organisational Structure and Background

Directorate of Measures and Precious Metals (DMDM) is National Metrology Institute (NMI) and national authority on legal metrology with responsibilities for control of precious metals articles. DMDM is a part of Ministry of Finance and Economy.

As NMI the DMDM has task to maintain national measuring standards of SI units, perform their international comparisons and disseminate legal units of measurement by calibration of measuring standards and instruments.

As legal metrology authority tasks of DMDM include type approval and some verifications of measuring instruments, control of prepacked products and metrological supervision. DMDM has six local metrology branches located in Belgrade, Krusevac, Nis, Novi Sad, Subotica, and Zrenjanin. Verification of measuring instruments is performed by authorized bodies for tasks of verification of measuring instruments, or DMDM for those measuring instruments only for verification of which no authorized body exists.

Serbia is signatory of the Metre Convention (1879) and of the Convention establishing OIML. DMDM is Member of EURAMET and Associate Member of WELMEC, and signatory of the CIPM-MRA and OIML-MAA (DoMCs).

By the first Law on Measures in 1873, the metric system was introduced and the Office for control of measures and comparisons of prototypes used in control of measures was founded. The present Law on Metrology and Law on control of precious metals articles have been in force since 2010 and 2011, respectively.

Instruments are generally subject to type approval and verification unless otherwise stated. List of measuring instruments subject to legal control is given by Regulation on the kinds of measuring instruments for which verification is mandatory and intervals of their periodic verification (2010).

Type Approval

Type approval responsibility for measuring instruments subject to legal metrological control rests with the DMDM or designated bodies. DMDM has own test facilities but may use other accredited test laboratories. DMDM maintains a national database of type approvals. Fees are calculated on the basis of man-hours and material costs for any individual type approval. Fees are defined by legal ordinance. Type approval certificates and test results are issued in Serbian although official translations may be provided on request. The most numerous measuring instruments for which type approvals are issued are non-automatic weighing instruments, followed by, electricity meters, water meters and sphygmomanometers.

Initial Verification

New measuring instruments are subject to initial verification including measuring instruments that have not been verified before. National manufacturer, authorized importer or distributor, legal entity or natural person may submit measuring instrument to be initially verified.

Initial verification of measuring instruments is performed by authorized bodies for tasks of verification of measuring instruments, or DMDM for those measuring instruments for which verification no authorized body exists. Initial verification procedure is specified by regulation. In situ verification may be required where instruments are designed to be used in a permanent location. Verification fees are stipulated by ordinance.

Inspection and Reverification

Inspection activities are carried out by Department for Metrology Supervision of DMDM and its six local metrology branches. These activities pertain to: supervision of manufacture, trade, import, installation, use, maintenance and repair of measuring instruments; supervision and testing quantity of pre-packed products; and supervision of the operation of authorized bodies.

In-service measuring instruments are subject to re-verification, periodically within defined time intervals for certain kinds of measuring instruments. A measuring instrument shall be submitted to re-verification by its owner or those using the measuring instrument.

Typical re-verification intervals are:

weighing instruments used in trade 2 years
petrol pumps 1 year
cold water meters 5 years
gas meters 5 years
electricity meters 12 years
taximeters 1 years
law enforcement instruments 1 years

Fees for re-verification are the same as those for initial verification. Error allowances in service are generally MPE x 2 for weighing instruments. There is no provision, which permits repairers to re-verify instruments.

Legal Metrology Practitioners and Scope

DMDM has approximately 125 employees, about 35 of them are scientists and engineers with university degree engaged in type approvals but also occupied with fundamental metrology and calibrations as well. Another 67 people are engaged in control and supervision activities. Regular training courses are carried out for employees of DMDM and authorized bodies for tasks of verification of measuring instruments.

In case of doubt in the correctness of measuring instrument, interested person may request from authorized body or DMDM, the extraordinary verification of measuring instrument and issuing of examination report.

Sanctions

Sanctions are based upon a system of administrative penalties. A preventative enforcement policy is applied. Prosecutions are brought before a municipal authority for adjudication. Only cases involving fraud are generally subject to prosecution in the courts.

Instruments, found to be infringing legal requirements, will be prohibited from further use and may be sealed. In case that repair is not achievable, instrument will be prohibited from further use everlastingly.

Directive 90/384/EEC

The national regulation concerning non-automatic weighing instruments has been adapted to technical requirements of Directive 90/384/EEC and standard EN 45501 (which is identical with OIML Recommendation R76). The weighing instruments mentioned in Article 1.2(a) of the Directive are subject to national metrological controls.

No specific requirements have been implemented as regards the gravity value.

Directive 2004/22/EC (MID)

Directive was transposed by Regulation on Measuring Instruments that will be issued soon.
