Il est toutefois nécessaire, dans certains cas, de recourir à des méthodes de vérification par mesurage direct et le but du présent document est d'exposer les méthodes utilisables à cet effet. La situation du présent document dans la matrice GPS est donnée en annexe F.

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.
