Il existe trois normes de rondelles plates. La présente norme concerne les rondelles de grade A qui comportent une dureté minimale supérieure et des tolérances d'épaisseur plus sévères que celles fixées dans la norme NF E 25-513, qui traite des rondelles courantes de grade C. Latroisième norme, E 25-518, fixe les caractéristiques des rondelles épaisses employées dans les assemblages mécaniques ou destinées à l'assemblage de matériaux "tendres".

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.
