International Standards and Conformity Assessment for all electrical, electronic and related technologies

European Standards Organizations (ESOs)

CENELEC is a European regional standards organization that together with its sister organizations CEN, the European Committee for Standardization, and ETSI, the European Telecommunications Standards Institute, compose the so-called and known European Standards Organizations (ESOs) that are officially recognised by the European Commission and act as a European platform through which European Standards are developed.

In the European Union, only standards developed by CEN, CENELEC and ETSI are recognised as 'European Standards'. Hence, CENELEC closely cooperates with CEN and ETSI; working jointly in the interest of European harmonization, creating both standards requested by the market and harmonized standards in support of European legislation.

CEN, CENELEC, ETSI are the regional mirror bodies to their international counterparts, i.e. ISO (the International Organization for Standardization), IEC (the International Electrotechnical Commission) and ITU-T (the International Telecommunication Union, telecommunication standardization sector) respectively.


The European Committee for Standardization (CEN) is a business catalyst in Europe, removing trade barriers for European stakeholders such as industry, public administration, service providers, consumers and other stakeholders. Its mission is to foster the European economy in global trading, the welfare of European citizens, and the environment. Through its services CEN provides a platform for the development of European Standards and other specifications.

CEN’s 34 National Members work together to develop voluntary European Standards (ENs) in various sectors to build a European Internal Market for goods and services and to position Europe in the global economy. By supporting research, and helping disseminate innovation, standards are a powerful tool for economic growth. More than 60.000 technical experts as well as business federations, consumer and other societal interest organizations are involved in the CEN network that reaches over 480 million people.
