EU committee takes place in close cooperation with WELMEC to put on the implement of these two directives:
  • Directive 2014/32/EU Measuring instruments (MID)
  • Directive 2014/31/EU Non-automatic weighing instruments (NAWI)

3. Promoting legislations of pre-packaged products and pack sizes
  • Directive 76/211/EEC and 75/107/EE define the quantities contained in pre-packaged products
  • Directive 2007/45/EC defines the rules for nominal quantities of prepackaged products

4. Simplification of 8 legal metrology directives
Directive 2011/17/EU repeals 8 'old approach' directives and provides for a transition period, clarifying that a range of products such as non-potable cold-water meter will be ensured in practice either by the voluntary application of the international and European standards which have been developed or by the application of national provisions laying down technical specifications based on such standards or, in line with the principles of better law-making.

  • thermal energy meters (MI-004)
  • measuring systems for continuous and dynamic measurement of quantities of liquids other than water (MI-005)
  • automatic weighing instruments (MI-006)
  • taximeters (MI-007)
  • material measures (MI-008)
  • dimensional measuring instruments (MI-009)
  • exhaust gas analysers (MI-010)
