Hot rolled weldable steel bars for pressure purposes with specified elevated temperature properties
This European Standard specifies the technical delivery conditions for hot rolled weldable steel bars for the construction of pressure equipment for use at elevated temperatures.
The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this European Standard.
NOTE Once this European Standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive 97/23/EC are satisfied, needs to be done.
Warmgewalzte schweißgeeignete Stäbe aus Stahl für Druckbehälter mit festgelegten Eigenschaften bei erhöhten Temperaturen
Diese Europäische Norm legt die technischen Liegerbedingungen für warmgewalzte, schweißgeeignete Stäbe
aus Stahl für den Bau von Druckbehältern fest, die für den Einsatz bei erhöhter Temperatur bestimmt sind.
Für Erzeugnisse, die nach dieser Europäischen Norm geliefert werden, gelten zusätzlich die allgemeinen
technischen Lieferbedingungen nach EN 10021.
ANMERKUNG Nach Veröffentlichung dieser Norm im EU-Amtsblatt (OJEU) unter der Richtlinie 97/23/EG ist die
Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR) der Richtlinie 97/23/EG auf die technischen
Daten von Werkstoffen in dieser Europäischen Norm beschränkt, und es darf nicht angenommen werden, dass damit die
Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil festgestellt ist. Folglich müssen die in dieser Werkstoffnorm
angegebenen technischen Parameter im Hinblick auf die konstruktiven Anforderungen dieses bestimmten
Ausrüstungsteils ermittelt werden, um damit zu verifizieren, dass den ESR der Richtlinie 97/23/EG entsprochen wird.
Barres laminées à chaud en acier soudables pour appareils à pression, avec des caractéristiques spécifiées aux températures élevées
La présente Norme européenne spécifie les conditions techniques de livraison des barres laminées à chaud en aciers soudables pour la construction des appareils à pression utilisés à des températures élevées.
Les conditions techniques générales de livraison de l'EN 10021 s'appliquent également aux produits livrés conformément à la présente Norme européenne.
NOTE Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JO) en lien avec la Directive 97/23/CE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 97/23/CE se limite aux données techniques relatives aux matériaux spécifiées dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, il doit être procédé à l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences relatives à la conception de cet équipement spécifique, afin de vérifier que les exigences essentielles de sécurité de la Directive relative aux équipements sous pression 97/23/CE sont satisfaites.

1 Scope This European Standard specifies the technical delivery conditions for hot rolled weldable steel bars for the construction of pressure equipment for use at elevated temperatures. The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this European Standard. NOTE Once this European Standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive 97/23/EC are satisfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document.
