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

This European Standard specifies the requirements, under the regime of the EU Directive 97/23/EC on Pressure Equipment (PED), for the establishment of the technical delivery conditions in the form of:
-   harmonized European Standards for material;
-   European Approval for Materials (EAM);
-   Particular Material Appraisal (PMA)
for metallic materials for pressure equipment in all product forms. Welding consumables are not covered by this standard.
This European Standard was developed predominantly on the basis of steel, nickel and nickel-based materials. However, application to other materials is not restricted but should consider specific aspects relevant to the material concerned.

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

Diese Europäische Norm legt die Anforderungen entsprechend der EU-Richtlinie 97/23/EG für Druckgeräte (DGRL) für die Festlegungen der technischen Lieferbedingungen als:
-   harmonisierte Europäische Werkstoffnorm;
-   Europäische Werkstoffzulassung (EAM);
-   Werkstoff-Einzelgutachten (PMA),
für metallische Werkstoffe für Druckgeräte in allen Erzeugnisformen fest. Schweißzusätze werden in dieser Norm nicht behandelt.
Diese Europäische Norm wurde vorrangig auf der Grundlage von Stahl , Nickel- und nickelbasierten Werkstoffen entwickelt. Sie darf jedoch auf andere Werkstoffe angewendet werden, wobei jedoch besondere Aspekte bezüglich des betreffenden Werkstoffs berücksichtigt werden sollten.

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

La présente Norme européenne spécifie les exigences, selon le régime de la Directive européenne 97/23/CE concernant les équipements sous pression (DESP), pour l'établissement des conditions techniques de livraison sous forme de :
-   Normes européennes harmonisées de matériau ;
-   Approbations Européennes de Matériaux (AEM) ;
   Evaluation Particulière de Matériaux (EPM) ;
pour les matériaux métalliques destinés aux équipements sous pression sous toutes les formes de produits. Les produits consommables pour le soudage ne relèvent pas de la présente norme.
La présente Norme européenne a été développée principalement pour les aciers, le nickel et les matériaux à base de nickel. Cependant, son application à d’autres matériaux n’est pas exclue mais il convient de prendre en compte les aspects spécifiques aux matériaux en question.
