Disclaimer
NEN-Hub is an independent educational platform and is not a replacement for the official NEN standards. For any work, the current official NEN publication always applies. NEN standards are copyrighted and available for purchase at nen.nl.
How is the content made?
Guides, glossary terms and practice questions were drafted with the help of AI tools and then checked and updated by the maintainer; they have not been reviewed by a certified NEN 3140 instructor or inspector. The translations (EN, RU, UA, PL) are largely machine-generated and have not been checked by native-speaking professionals — Dutch is always the leading version. Found a mistake? Email us and we will correct it.
