Fasteners. Clearance holes for bolts and screws. Counterbores and countersinks. Dimensions.

Il est apparu intéressant à la commission de normalisation "Boulonnerie" de regrouper en un seul fascicule de documentation les dimensions des usinages à réaliser dans les pièces d'un assemblage pour y loger soit le corps, soit la tête des vis ou les écrous.

ZOOM ON ... the Requirements department

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.

With Requirements, quickly access the main part of the normative text!
