European Standards (EN) are technical standards which have been ratified by one of the three European standards organizations: European Committee for Standardization (CEN), European Committee for Electrotechnical Standardization (CENELEC), or European Telecommunications Standards Institute (ETSI). All ENs are designed and created by all interested parties through a transparent, open, and consensual process.
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 member countries. 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 over any national standard.
Numbering and naming
|EN 1 to EN 99||Original work of the European Committee for Standardization (CEN)|
|EN 1000 to EN 1999||Original work of the European Committee for Standardization (CEN)|
|EN 2000 to EN 6999||Standards prepared by the AeroSpace and Defence Industries Association of Europe (ASD STAN)|
|EN 10000 to EN 10999||Number range to reserve|
|EN 20000 to EN 29999||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.|
|EN 50000 to EN 59999||CENELEC standards|
|EN 60000 to EN 69999||CENELEC standards based on International Electrotechnical Commission (IEC) standards, with or without amendments|
|EN 100000 to EN 299999||CENELEC Electronic Components Committee (CECC) documents for quality evaluation for electronic components|
|EN 300000 to EN 399999||Standards of the European Telecommunications Standards Institute (ETSI)|
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.
When an EN is adopted by a national standards body into the national body of standards, it is given the status of a national standard (e.g. German Institute for Standardisation (DIN), Austrian Standards International (ÖNORM), Austrian Standards International (SN)). The name is then prefixed by the country-specific abbreviation (e.g. ÖNORM EN ...), and the number of the European standard is usually adopted, e.g. DIN EN ISO 2338:1998 or ÖNORM EN ISO 9001:2000.
