Low-voltage switchgear and controlgear assemblies - Part 2 : particular requirements for busbar trunking systems (busways)

Le présent document modifie la norme NF EN 60439-2 pour compléter la liste des essais de type, introduire les essais de cycles thermiques et préciser les modalités de la vérification de la tenue en court-circuit. Ce document entre dans le champ d'application de la Directive Basse Tension n° 73/23/CEE du 19/02/1973 modifiée par 93/68/CEE du 22/07/1993.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

• mandatory clauses to satisfy,
• non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.
