Geschweißte Stahlrohre für Druckbeanspruchungen - Technische Lieferbedingungen - Teil 4: Elektrisch geschweißte Rohre aus unlegierten Stählen mit festgelegten Eigenschaften bei tiefen Temperaturen
Dieses Dokument legt die technischen Lieferbedingungen für elektrisch geschweißte Rohre mit kreis-förmigem Querschnitt aus unlegiertem Qualitätsstahl mit festgelegten Eigenschaften bei tiefen Temperaturen in zwei Prüfkategorien fest.
ANMERKUNG 1 Die Rohrgüten sind vorgesehen zur Unterstützung der grundlegenden Anforderungen der EU Richtlinie 2014/68/EU bezüglich Druckgeräten mit festgelegten Eigenschaften bei tiefen Temperaturen und sie decken alle festgelegten Kategorien nach Artikel 13 der Richtlinie ab.
ANMERKUNG 2 Nach Veröffentlichung dieser Norm im EU-Amtsblatt (ABl.) ist die Annahme ihrer Konformität mit den grundlegenden Sicherheitsanforderungen (ESR) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in dieser 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 Druckgeräterichtlinie entsprochen wird. Dies muss durch den Ausleger oder den Hersteller der Druckgeräte geschehen, der auch den nachfolgenden Herstellungsprozess berücksichtigen muss, der die Eigenschaften des Grundmaterials verändern kann.
Tubes soudés en acier pour service sous pression - Conditions techniques de livraison - Partie 4: Tubes soudés électriquement en acier non allié avec caractéristiques spécifiées à basse température
Le présent document spécifie les conditions techniques de livraison de deux catégories d’essai des tubes soudés électriquement à section circulaire, avec caractéristiques spécifiées à basse température, en acier de qualité non allié.
NOTE 1 Ces nuances sont destinées à remplir les exigences essentielles de la directive 2014/68/UE sur les équipements sous pression avec caractéristiques spécifiées à basse température concernant toutes les catégories pertinentes comme exposé dans l’article 13 de cette Directive.
NOTE 2 Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JOUE), la présomption de conformité avec les exigences essentielles de sécurité (ESR) de la Directive 2014/68/UE se limite aux données techniques des matériaux spécifiées dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences de conception d’un équipement spécifique, pour vérifier que les exigences essentielles de sécurité (ESRs) de la Directive sur les équipements sous pression soient satisfaites, doit être effectuée par le concepteur ou le fabricant de l’équipement sous pression, en tenant aussi compte de toutes les procédures ultérieures de fabrication qui peuvent affecter les propriétés des matériaux de base.

1 Scope
This document specifies the technical delivery conditions for two test categories of electric welded
tubes of circular cross section, with specified low temperature properties, made from non-alloy quality
steel.
NOTE 1 These tube grades are intended to support the essential requirements of EU Directive 2014/68/EU in
respect of pressure equipment with specified low temperature properties covered under all relevant Categories
as set out in Article 13 of that Directive.
NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of
conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data
for the materials in this standard and does not presume adequacy of the material for a specific item of pressure
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 are
satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account
the subsequent manufacturing processes which may affect properties of the base materials.
