About CEN

The European Committee for Standardization is one of three European Standardization Organizations (together with CENELEC and ETSI) that have been officially recognized by the European Union and by the European Free Trade Association (EFTA) as being responsible for developing and defining voluntary standards at European level.


The voluntary European certification mark demonstrating conformity with European Standards

In a Single European Market there is a need for a single European mark: one standard, one test, one mark!

CEN and CENELEC are the two co-owners of the Keymark but the certification schemes are operated by professional and qualified certification bodies, who are all accredited against ISO/IEC 17065 by members of the European co-operation for Accreditation (EA).


The general rules for the Keymark system are recorded in the CEN-CENELEC Internal Regulations - Part 4 (pdf format)
