1) What is a Harmonized Standard?
A harmonized standard "is a European standard elaborated on the basis of a request from the European Commission to a recognized European Standards Organisation (CEN, CENELEC or ETSI) to develop a European standard that provides solutions for compliance with a legal provision. Such a request provides guidelines which requested standards must respect to meet the essential requirements or other provisions of relevant European Union harmonization legislation.
Compliance with harmonized standards provides a presumption of conformity with the corresponding requirements of harmonization legislation. Manufacturers, other economic operators or conformity assessment bodies can use harmonised standards to demonstrate that products, services or processes comply with relevant EU legislation."

CEN and CENELEC standards can be purchased for a reasonable fee from CEN and CENELEC's Members, the National Standards Organizations:
and also from:
NB: Certain CEN and/or CENELEC Workshop Agreements (CWAs), mainly in the ICT field, are available free of charge under special arrangements, for example, where industry has offset the loss of sales. Visit the CEN website to see which CWAs can be freely downloaded via the following link:

6) Is there copyright on European Standards?
The distribution of European Standards is the responsibility of the CEN and CENELEC Members, the National Standards Organisations. Consequently, CEN and CENELEC have entrusted their National Standards Organisations with the protection of their copyright interests, each in their respective territories.
Therefore, any reproduction, distribution, resale or communication of standards in any medium, is forbidden without the formal written authorization from the National Standards Organisations where the standard was purchased from.

CEN and CENELEC are not certification bodies and therefore certification is not part of their activities.

13) Where do I find EC directives and regulations?
The full text of European Directives, Regulations and other EU legislation can be obtained from EUR-LEX
