Le présent document a pour objet de définir les méthodes d'essai à utiliser pour la détermination des caractéristiques géométriques suivantes des tôles et bandes magnétiques en acier : - planéité ; - courbure résiduelle ; - rectitude ; - déviation par rapport à la ligne de cisaillage due aux tensions internes ; - hauteur de bavure des rives cisaillées. Il s'applique aux tôles magnétiques en acier destinées à la construction de circuits magnétiques et correspondant aux articles B2, C21 et C22 de la IEC 60404-1:2000.

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.
