Pressure equipment - Part 4: Establishment of technical delivery conditions for metallic materials

This Part of the European Standard specifies the requirements for the establishment of the technical delivery conditions in form of: - European material Standard; - European approval for material (EAM); - Particular material appraisal; for metallic materials for pressure equipment in all product forms. When properties specific to an application are relevant, e.g. creep, reference should also be made to the appropriate product standard.

Druckgeräte - Teil 4: Erstellung von technischen Lieferbedingungen für metallische Werkstoffe

Dieser Anhang legt die Anforderungen für die Festlegung der technischen Lieferbedingungen als: - Europäische Werkstoffnorm; - Europäische Werkstoffzulassung (EAM); - Werkstoff-Einzelgutachten; für metallische Werkstoffe für Druckgeräte in allen Erzeugnisformen fest. Wenn Eigenschaften für eine bestimmte Anwendung relevant sind, z.B. Kriechen, sollte der Verweis auf entsprechende Normen gemacht werden.

Equipements sous pression - Partie 4: Etablissement des conditions techniques de livraison des matériaux métalliques

La présente partie de la Norme européenne spécifie les exigences relatives à l'établissement des conditions techniques de livraison sous forme de: - norme européenne de matériaux, - approbation européenne de matériaux (EAM), - évaluation particulière de matériaux, pour les matériaux métalliques destinés aux équipements sous pression sous toutes les formes de produits. Lorsque certaines propriétés spécifiques à une application sont pertinentes, par exemple le fluage, il convient de faire également référence à la norme de produit correspondante.
