Romania comprises three historical provinces: Moldavia, Transylvania and Wallachia and covers a land area of 238391 km2. The administrative organization of Romania features 41 counties. It has a population of 21,8 million inhabitants, of which 2 million live in Bucharest, the capital city. The political system of Romania is a Parliamentary democracy.

Organizational structure and background

The Romanian Bureau of Legal Metrology (BRML), established by Government Ordinance no. 20/1992 regarding the metrological activities, is the specialized body of central public administration, responsible for the national coordination and control of legal metrological activities, which assures the metrological regulations, technical means and actions needed to provide credibility to the measurement results throughout the country.

BRML is a public institution with legal personality, subordinated to the Ministry of Economy, Trade and the Business Environment

The main competences and tasks of BRML are established by Government Decision no. 193/2002, regarding the organization and operation of the Romanian Bureau of Legal Metrology, amended by Government Decision no. 289/2005.

BRML has the competence to:

-          lay down technical and metrological requirements for measuring instruments subject to legal metrological control and contribute to the development of the legal metrological framework by approximation to the European regulations and international practices;

-          attest national standards and assure dissemination of measurement units;

-          hold, improve, preserve and use national standards;

-          evaluate measuring instruments against technical and metrological requirements established in the applicable regulations;

-          carry out legal metrological control of measurements, measuring instruments and activities related to measurements and measuring instruments;

-          ascertain contraventions and apply penalties in the fields for which it was nominated according to the legislation in force.


BRML has the following main tasks:

-          elaborates development strategies and programs on metrology;

-          supervises and controls the national implementation of the regulations from its sphere of competence;

-          contributes to the elaboration of draft normative documents on metrology and monitors their correlating with other applicable norms in the field;

-          elaborates legal metrology instructions, legal metrology norms and EEC legal metrology norms;

-          participates in the technical assessment of the bodies seeking recognition for notification;

-          disseminates measurement units to measuring instruments which are not subject to legal metrological control;

-          assures traceability of national standards to international standards;

-          represents the Romanian interests to international and regional metrology bodies and organizations and co-operates with similar institutions from other countries or international bodies;

-          performs scientific research in the metrology field;

-          coordinates and carries on national programs in metrology with national and/or international financing;

-          concludes, under the law conditions, conventions, protocols or other documents for recognition of other metrological documents or activities.

These competences and tasks are carried out through an organizational structure where an important position is occupied by the National Institute of Metrology (INM), a distinct entity subordinated to BRML.

Upon regional level, BRML exercises its authority through 8 regional divisions of legal metrology – named DRMLs (Bucuresti, Bacau, Brasov, Cluj-Napoca, Constanta, Craiova, Ploiesti, Timisoara).

BRML also comprises the Department for Inspection and Market Surveillance (DISP) which is independent from the point of view of decision making and finances.

Further information on BRML and INM is available at www.brml.ro and www.inm.ro .

The first Romanian metrology act, “Law on the adoption of the metric system of weights and measures”, was adopted in 1864. In 1883, Romania joined the Metre Convention. At present, Romania is an OIML member and WELMEC member, while the National Metrology Institute is signatory of the CIPM-MRA and EURAMET member. The metrological activity in Romania is regulated by the Government Ordinance no. 20/1992 approved by Law no. 11/1994, with subsequent amendments.

The first national metrology authority was the Central Service of Weights and Measures established in 1889. It operated under various denominations and with different organizational structures, being the predecessor of the present Romanian Bureau of Legal Metrology.

The measuring instruments subject to legal metrological control as well as the applicable control methods are contained in the Official List approved by Order no. 48/2010 of the BRML Director General. The Official List is updated periodically. Most of the measuring instruments are subject to type approval, initial verification and mandatory re-verification.


Type approval and EEC type approval

In Romania, the type approval certificates or EEC type approval certificates are issued by BRML. In principle, the tests are performed by the INM laboratories. In some cases, BRML recognizes the test results provided by other laboratories from Romania or from other countries.



Initial verification

The initial verification of the categories of measuring instruments is performed in the laboratories of the 8 regional legal metrology divisions of BRML, in the INM laboratories or in other laboratories authorized by BRML.

The EEC initial verification is performed only in the BRML laboratories.

The verification fees are indicated in the Tariff List LT 2009 approved by Government Decision no. 712/2009. This list is periodically updated.


Inspection and re-verification

A mandatory re-verification system operates through periodical verification and verification after repair / modification. These verifications are performed in the BRML laboratories or in laboratories authorised by BRML.

The maximum verification intervals are indicated in the Official List approved by the Director General of BRML.

Here are a few examples:


1 year

weights of classes E2, F1, F2, M1, M2, M3

1 year

weighing instruments

1 year

fuel dispensers

1 year

cold water meters

5 years

gas meters

8 years

electricity meters

8 years

heat meters

4 years

law enforcement instruments

1 year


The maximum permissible errors on re-verification are mainly the same as on initial verification.

Besides re-verification, the legal metrological control of measuring instruments in use is performed through inspection, unscheduled testing and market surveillance by DRML and DISP inspectors.

The metrological control of pre-packages is performed by DRML inspectors. The fees charged for the verification of pre-packages actual content are indicated in the Tariff List approved by Government Decision no. 97/2011 and are paid by packers/importers.


Legal Metrology Practitioners and Scope

According to the legal regulations in force, the maximum number of employees that BRML can have amounts to 780. At present, 560 employees are involved in the regional legal metrology divisions and 110 in the National Metrology Institute (INM).

The INM staff carries out research activities, calibrations and type evaluation testing.



The BRML inspection officers report the metrological legislation infringements and apply penalties. The maximum amount of a penalty is about 5500 euro.

In some cases, the measuring instruments which are object of a sanction are sealed and confiscated in order to prevent their future use. The cases of fraudulent use of measuring instruments are taken to the law court.


Implementation of European Directives

Romania has transposed and implemented entirely the European Acquis in metrology and pre-packages field.

The conformity assessment of the non-automatic weighing instruments under the European Directive 2009/23/EC (90/384/EEC) and of the measuring instruments under European Directive 2004/22/EC is carried out by notified bodies.

The market surveillance of these measuring instruments is performed by DISP inspectors.

In Romania all the measuring instruments under the European Directive 2004/22/EC are subject to legal metrological control.
