NEN is a multi-faceted organization. We do not just issue standards, guidelines and publications, we also offer training programs and advice on practical applications. We are also regularly looking for new committee members who want to cooperate in developing a new standard. Please ask us your questions or give us your comments.

Examining standards at NEN?

If you do not want to purchase a standard, but just want to examine a specific standard, you can do so at NEN in Delft. You can examine all the standards there, but you cannot store them or copy any contents of the standards. We are open workdays from 9 AM to 5 PM.


Just like any book, CD-ROM or any other publication, the standards – both on paper and digital – are protected by copyright. Read more about this in the brochure: NEN Auteursrecht..
