European Standards are a key component of the Single European Market. They are crucial in facilitating trade and have high visibility among manufacturers inside and outside the European territory. A standard represents a model specification, a technical solution against which a market can trade.
European Standards must be transposed into a national standard in all EU member states. This guarantees that a manufacturer has easier access to the market of all these European countries when applying European Standards. Member countries must also withdraw any conflicting national standard: the EN supersedes any national standard. The current trend in Europe is oriented towards the harmonization of national standards under the Euronorm family.[5] Here, Euronorm becomes the equivalent of a national standard in all member countries and replaces any prior conflicting national standard.[6]
Obsolete numbering for standards adopted by the International Organization for Standardization (ISO) adopted standards. ISO NNNN" became "EN 2NNNN", e.g. ISO 2338 = EN 22338 (currently: EN ISO 2338)
EN 40000 to EN 49999
Refer to IT standards and were developed by CEN or CENELEC.
Since standards are updated as needed (they are reviewed for currency approximately every five years), it is useful to specify a version. The year of origin is added after the standard, separated by a colon, example: EN 50126:1999.
In addition to the EN standards mentioned, there are also the EN ISO standards with the numbers ISO 1 to 59999 and the EN IEC standards from IEC 60000 to 79999, as well as EN standards outside the defined number ranges.
European Standards can be found on the respective Catalogues of the European Standardization Bodies (CEN, CENELEC and ETSI). The national adoptions of the European Standards can be found on the respective catalogues of the National Standardization Bodies or on the websites of the authorised resellers.
European Standards and the European legislation
CEN develops European Standards for a wide range of products, materials, services and processes. Some sectors covered by CEN include transport equipment and services, chemicals, construction, consumer products, defence and security, energy, food and feed, health and safety, healthcare, digital sector, machinery or services. CEN adopts ISO standards in Europe, through the prefix “EN ISO” and cooperates with the International Standardization Organization through the Vienna Agreement, avoiding duplication of work and coherency in their respective catalogues of standards.
CEN develops Harmonized Standards supporting the General Product Safety Regulation (GPSR) / General Product Safety Directive (GPSD), as well as supporting a wide range of New Legislative Framework / New Approach directives and regulations. Harmonised standards provide presumption of conformity with the Essential Requirements in certain pieces of EU legislation.[8]
CENELEC, the European Committee for Electrotechnical Standardization is the European Standardization organization corresponding to the International Electrotechnical Commission (IEC), or IEC International Standards, adopted in Europe.
CENELEC standards support the application of the Low Voltage Directive, Electromagnetic Compatibility Directive, Radio Equipment Directive, Ecodesign, Energy Efficiency Labelling, Machinery or Medical Devices, amongst other European legislation. Some New Legislative Framework Directives and Regulations include:
Low Voltage Directive – LVD or Directive 2014/35/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of electrical equipment designed for use within certain voltage limits
Electromagnetic Compatibility Directive – EMCD or Directive 2014/30/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to electromagnetic compatibility
Machinery Directive, Machinery Safety Directive, MD or Directive 2006/42/EC of the European Parliament and of the Council of 17 May 2006 on machinery. Machinery Safety Regulation, or MR, or Regulation (EU) 2023/1230 of the European Parliament and of the Council of 14 June 2023 on machinery
Radio Equipment Directive – RED or Directive 2014/53/EU of the European Parliament and of the Council of 16 April 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of radio equipment
Energy efficiency labelling regulation and Ecodesign directive and associated implementing regulations,
For four European standards the European Court of Justice decided on 5 March 2024 that these must be made available free of charge because these standards are part of European Union law.[10]
