(Main)Flat products made of steels for pressure purposes - Part 2: Non-alloy and alloy steels with specified elevated temperature properties
Flat products made of steels for pressure purposes - Part 2: Non-alloy and alloy steels with specified elevated temperature properties
This European Standard specifies requirements for flat products for pressure equipment made of weldable nonalloy
and alloy steels with elevated temperature properties as specified in Table 1.
The requirements and definitions of EN 10028-1 also apply.
NOTE Once this European Standard is published in the EU Official Journal (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 (Part 1 and this Part 2 of the series) 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 Directive 97/23/EC are satisfied, needs to be done.
Flacherzeugnisse aus Druckbehälterstählen - Teil 2: Unlegierte und legierte Stähle mit festgelegten Eigenschaften bei erhöhten Temperaturen
In dieser Europäischen Norm sind die Anforderungen an Flacherzeugnisse für Druckbehälter aus den
schweißgeeigneten unlegierten und legierten Stählen nach Tabelle 1 mit Eigenschaften für den Einsatz bei
erhöhten Temperaturen festgelegt.
Zusätzlich gelten die Anforderungen und Begriffe in EN 10028-1+A1:2009.
ANMERKUNG Nach Veröffentlichung dieser Europäischen Norm im EU-Amtsblatt (OJEU) unter der Richtlinie 97/23/EC
ist die Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR) der Richtlinie 97/23/EC auf die
technischen Daten von Werkstoffen in dieser Europäischen Norm (Teil 1 und dieser Teil 2 der Normenreihe) 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/EC entsprochen wird.
Produits plats en aciers pour appareils à pression - Partie 2: Aciers non alliés et alliés avec caractéristiques specifiées à température élevée
La présente Norme européenne spécifie les prescriptions relatives aux produits plats pour appareils à pression en
aciers non alliés et alliés, aptes au soudage, avec caractéristiques à température élevée, telles que spécifiées dans
le Tableau 1.
Les prescriptions et définitions de l’EN 10028-1 :2007 + A1 :2009 s’appliquent également.
NOTE Après publication de la présente Norme européenne dans le Journal Officiel de l'UE (OJEU) sous la Directive
97/23/EC, la présomption de conformité aux Exigences Essentielles de Sécurité (ESRs) de la Directive 97/23/EC se limite aux
données techniques des matériaux de la présente Norme européenne (Partie 1 et la présente Partie 2 de la série) et ne
suppose pas l'adéquation du matériau à un élément ou à un équipement spécifique. En conséquence, l'évaluation des données
techniques énoncées dans la présente norme de matériau en fonction des exigences de conception de cet élément spécifique
d'équipement pour vérifier que les ESR de la Directive 97/23/EC sont respectées, doit être effectuée.
