Country Information Luxembourg

Luxembourg has a population of 590,000 and covers an area of 2,586 sq km. It is a representative democracy in the form of a constitutional monarchy. The Grand Duke, Head of State, forms the constitutional executive with the government. The nationally elected Chamber of Deputies shares the exercise of legislative power with the Grand Duke.

For administrative purposes Luxembourg is divided into 3 districts and 102 communes. The commune is an autonomous authority, operated by local representatives under the control of the central authority.

Luxembourg has a central government legal metrology structure. The Service de Métrologie Légale which, since its creation, was linked to the Administration des Contributions, has become part of an administration created in 2008 in the Ministry of Economy, the Institut luxembourgeois de la normalisation, de l'accréditation, de la sécurité et qualité des produits et services (ILNAS). Its main functions concern the verification of measuring instruments and the application of the legal units of measurement.

A uniform system of weights and measures was first introduced in Luxembourg in 1816, the metric system being brought in by a law of 1842. A Royal grand-ducal decree of 1882 provided more framework legislation and allocated the legal control of weights and measures to a special officer subordinated to the Direction des Contributions.

The amending grand-ducal regulation of 10 December 2009 implements the DIRECTIVE 2009/3/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 11 March 2009 amending Council Directive 80/181/EEC on the approximation of the laws of the Member States relating to units of measurement.

No type approvals service is provided.

These are performed by the 4 engineers and 4 technical officers at the Service de Métrologie Légale. Fees are set by law 'Règlement grand-ducal du 31 octobre 2008 portant tarification des prestations du Service de métrologie légale', Mémorial A- Nr. 172 du 28 novembre 2008. The Memorial is the official published gazette of legislation.

The initial verification function is not subject to any external contracting out to private laboratories. There are no instrument manufacturers in Luxembourg and therefore no system of manufacturer self-declaration or EN29000 experience within the Service.

A mandatory reverification system operates in the Grand Duchy. Frequencies are specified in law:

  • Weighing instruments in trade use: 3 years
  • Petrol pumps: 3 years
  • Cold water meters (subject to a 10 year replacement cycle): 10 years
  • Weighing instruments used for medical or law enforcement purposes: 3 years

In 2017 the Service inspected 1100 non-automatic weighing instruments with a 10 % failure rate. 3% of the 2300 petrol pumps inspected in the same period failed. Maximum permissible errors are generally based on mpe x 2 ; and mpe x 1 for petrol pumps.

The 4 engineers in the Service de Métrologie, who are also the Chief and Assistant Chief of the Service, are engineers in electronics or mechanics.The Service will investigate complaints about instruments and short measure and will advise businesses on legal requirements. It also carries out control of volume and mass prepackages duties in accordance with the grand-ducal regulation of 19 octobre 1977.

There is no system of financial administrative penalties in Luxembourg. Cases may be taken to court where they involve the fraudulent or incorrect use of equipment. Instruments in cases involving illicit profit may be confiscated. Instruments found to be exceeding mpe may be rejected and put out of service.

Luxembourg implemented this Directive by 'Règlement grand-ducal du 26 janvier 2016 concernant les instruments de pesage à fonctionnement non automatique (Memorial A-No.11 du 3.02.2016)’.

The use of accuracy classes for specific applications is not prescribed.

Luxembourg implemented this Directive by ‘Règlement grand-ducal du 26 janvier 2016 concernant les instruments de mesure (Memorial A-No.11 du 3.02.2016)’.
