Comite Europeen de Normalisation or European Committee for Standardisation


The European Committee for Standardisation or Comité Européen de Normalisation (CEN), is a private non-profit organisation whose mission is to foster the European economy in global trading, the welfare of European citizens and the environment by providing an efficient infrastructure to interested parties for the development, maintenance and distribution of coherent sets of standards and specifications.

CEN was founded in 1961. Its thirty national members work together to develop European Standards (ENs) in various sectors to build a European internal market for goods and services and to position Europe in the global economy.

Some of these standards are voluntary, whereas other standards such as harmonized standards have been made effectively mandatory under EU law.

More than 60.000 technical experts as well as business federations, consumer and other societal interest organisations are involved in the CEN network that reaches over 460 million people. CEN is the officially recognized standardisation representative for sectors other than electrotechnical and telecommunications.

CEN’s National Members are the National Standardization Bodies (NSBs) of the 28 European Union countries, the Former Yugoslav Republic of Macedonia, and Turkey plus three countries of the European Free Trade Association (Iceland, Norway and Switzerland). There is one member per country.

Principles governing standards development at CEN:

    • Standards are developed through a consensus process;
    • Participants in standards development represent all interests concerned: industry, authorities and civil society, contributing mainly through their national standards bodies;
    • Draft standards are made public for consultation at large;
    • The final, formal vote is binding on all members;
    • The European Standards (ENs) must be transposed into national standards and conflicting standards withdrawn

List of Standards/Search:

So far, CEN has published 13.420 publications (end February 2009). You can search for a particular standard at this page on official website of CEN.


All European Standards (EN) and drafts (prEN), as well as any other approved document (Technical Specifications (CEN TS), Technical Reports (CEN TR) and CEN Workshop Agreements (CWA), can be obtained from any of its National Members. CEN itself does not sell these publications
