Measuring instruments

Measuring instruments range from waters meters to weighing machines. They are important for trade, consumers and industry as they ensure accuracy of measurement, transparency and fairness.

Evolution of the legislation

  • Framework  Directive (71/316/EEC) and a number of specific directives on measuring instruments - the objective was to allow free movement of goods between the EU countries and guarantee that manufacturing would be in conformity with national rules for the home market;
  • Directive 2009/34/EC is the codification replacing Framework Directive 71/316/EEC;
  • Directive 2004/22/EC on measuring instruments (MID), amended by Directive 2009/137/EC:
    • covers 10 categories of measuring instruments, and abolishes the corresponding previous legislation;
    • adopts a decisively modern regulatory approach, leaving much more room for technological innovation and more choice for manufacturers in conformity assessment procedures;
    • aligned Community legislation on international standards, in particular of the OIML and covering the electronic revolution that has characterised measuring instruments since the 1970s;
  • Directive 90/384/EEC on Non-Automatic Weighing Instruments (NAWI) based on the same approach, was adopted in 1990. Directive 2009/23/EC is the codification replacing NAWI.

Implementation of these Directives takes place in close cooperation with WELMEC, the Western European Legal Metrology Cooperation, which serves as a platform for cooperation among 29 European countries' authorities.

Report on MID

In 2010 the Commission held a public consultation on the Measuring Instruments Directive 2004/22/EC. The aim of the consultation was to gather feedback on the implementation of the Directive and on the reasons and impacts of possible changes:

Normative documents

According to Article 13.2 of Directive 2004/22/EC on measuring instruments, normative documents by the 'Organisation Internationale de la Métrologie Légale' (OIML) may be identified as giving presumption of conformity with the essential requirements of the Directive after an advisory vote in the Measuring Instruments Committee. The references to normative documents have been published in the following publications of the Official Journal:
