Le présent document spécifie des techniques de contrôle par radiographie numérique des assemblages de plaques ou de tubes soudés par fusion de matériaux métalliques. Pour ces techniques radiographiques, qui sont divisées en deux classes (techniques de base et techniques améliorées), il définit les principes de compensation pour le ratio contraste-bruit permettant d''obtenir une sensibilité suffisante et fixe les exigences générales relatives à la préparation de la surface, aux radiogrammes numériques, au marquage, au recouvrement des images numériques et à la qualité d''image. Il donne enfin des recommandations pour l''exécution des radiogrammes numériques. Il complète ainsi la série de normes existantes sur les contrôles par radiographies des assemblages soudés : NF EN ISO 17636-1, NF EN 12517-1 et NF EN 12517-2.

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!
