Foundry products - Guidelines for determining acceptance criteria of discontinuities on machined surfaces

Le présent document décrit des lignes directrices pour la définition et l'expression des critères d'acceptation des discontinuités détectables par examen visuel sur les surfaces usinées des pièces moulées, quel que soit l'alliage. Le contrôle visuel direct ou indirect des discontinuités, au même titre que chacun des procédés de contrôle non destructif, s'intègre dans une estimation générale ou particulière de la qualité de la pièce moulée, définie contractuellement (voir NF EN 1559-1) .

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!
