To ensure a coherent application of the measuring instruments directives, the Commission and WELMEC (European Cooperation in Legal Metrology) prepared a set of guidance documents.
Evolution of the legislation
- Directive 2014/32/EU on measuring instruments (MID), amended by Directive 2015/13/EU, replacing Directive 2004/22/EC
- covers 10 categories of measuring instruments, and abolishes the corresponding previous legislation, depending on Framework Directive 2009/34/EC codifying Directive 71/316/EEC
- adopts a decisively modern regulatory approach, leaving much more room for technological innovation and more choice for manufacturers in conformity assessment procedures
- aligns Community legislation on international standards, in particular of the OIML and covering the electronic revolution that has characterised measuring instruments since the 1970s
- Directive 2014/31/EU on non-automatic weighing instruments (NAWI) follows the same approach replacing Directive 2009/23/EC, the codification of the original Directive 90/384/EEC
Implementation of these directives takes place in close cooperation with WELMEC (European Cooperation in Legal Metrology) which serves as a platform for cooperation among 31 European country authorities.
To ensure a coherent application of the measuring instruments directives, the Commission and WELMEC prepared a set of guidance. The guidance documents were agreed by the Commission's measuring instruments working group that is composed of representatives of authorities, European federations, notified bodies and European standardisation organisations.

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.
- Commission services' working document (362 kB, includes the questions)
- All reactions to the public consultation of September to November 2010 (8 MB)
- Report on the Measuring Instruments Directive COM(2011)357 of 17 June 2011
The European Commission mandate (782 KB) to CEN, CENELEC and ETSI in the field of measuring instruments is leading to the creation of European standards that will enable interoperability of utility meters (water, gas, electricity and heat) and enhance energy efficiency and user empowerment.
The 2015 mandate M/541 concerns new European standards for the non-exploitation of errors by water and heat meters, metering small-scale delivery of active electricity to the grid and use of energy by electrical vehicles. The new standards are expected to be delivered by the end of 2017.
- Under Directive 2009/23/EC the reference of one harmonised standard on non-automatic weighing instruments has been published in the OJ C 300 of 11.9.2015 [replacing OJ C 153 of 4.6.1994 (p. 17)]
- Under Directive 2004/22/EC the references of harmonised standards have been published in the OJ C 218 of 24.7.2012 (p. 7)
According to Article 14.2 of Directive 2014/32/EU 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. To this end, references to the following normative documents have been published in the Official Journal and specific guidance provided (N.B. according to Article 52(2) of Directive 2014/32/EU references to the repealed Directive 2004/22/EC are construed as references to the current Directive):
