Dutch Standards

NEN develops different types of agreements; standards, practice guidelines or technical agreements. These are the differences between the agreements:

Dutch standard (NEN Standard)

  • constituent agreements;
  • broad representation of stakeholders;
  • according to consensus;
  • public comment period of at least 3 months;
  • duration of 1 year up to 3 years (depending on internationalization).

Result: a standard that has wide support and authority

Dutch pre-standard (NVN)

This is a temporary agreement with constituent demands but where provisions are missing, incomplete or are included without prejudice. The intention is to publish the agreement as Dutch standard (NEN Standard) if further testing has taken place or additions have been made
and agreement has been reached.

Dutch Practice guidelines (NPR)

  • informative appointment;
  • broad representation of stakeholders;
  • according to consensus;
  • public comment period of at least 3 months;
  • average turnaround time for 1 year.

Result: a practical implementation of the provisions of the standard. For example: explanations of standards, constructive possibilities, methods and manufacturing data.

Dutch technical arrangement (NTA)

  • requirements constituent appointment;
  • public understanding between two or more parties;
  • consensus is not required;
  • no public comment round;
  • short lead time. (short time scale)

Result: appointment that can be established quickly. This offers added value in areas where the developments are at high speed.
