Steel tubes for precision applications - Technical delivery conditions - Part 4: Seamless cold drawn tubes for hydraulic and pneumatic power systems
This European Standard specifies the technical delivery conditions for seamless cold drawn steel tubes of circular cross section used in hydraulic and pneumatic power systems with specified outside diameter D ≤ 80 mm. Tubes according to this document are characterised by having precisely defined tolerances on dimensions and a specified maximum surface roughness. The allowed pressure rates and upper temperatures are the responsibility of the customer in accordance with the state of the art and in application of the safety coefficients specified in the applicable regulations, codes or standards. Concerning the lower temperature range applicability the impact energy requirements are given at 0° C.
Präzisionsstahlrohre - Technische Lieferbedingungen - Teil 4: Nahtlose kaltgezogene Rohre für Hydraulik- und Pneumatik-Druckleitungen
Diese Europäische Norm legt die technischen Lieferbedingungen für nahtlose kaltgezogene Präzisionsrohre aus Stahl mit kreisförmigem Querschnitt für die Anwendung in hydraulischen und pneumatischen Druck-leitungssystemen mit Nennaußendurchmessern D 80 mm fest.
Rohre nach diesem Dokument sind durch genau definierte Grenzabmaße und eine festgelegte maximale Oberflächenrauheit charakterisiert.
Die Beachtung der zulässigen Druckbeaufschlagung und Höchsttemperaturen nach dem Stand der Technik und unter Anwendung der in den entsprechenden Vorschriften, Regelwerken oder Normen festgelegten Sicherheitskoeffizienten liegt in der Verantwortung des Anwenders. Für die Anwendungen im unteren Temperaturbereich wurden Anforderungen an die Kerbschlagarbeit bei 0 °C festgelegt.
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 Ausrüstungs¬teils ermittelt werden, um damit zu verifizieren, dass den ESR der Richtlinie 97/23/EG entsprochen wird.
Tubes de précision en acier - Conditions techniques de livraison - Partie 4 : Tubes sans soudure étirés à froid pour circuits hydrauliques et pneumatiques
La présente partie de l 'EN 10305 spécifie les conditions techniques de livraison pour les tubes sans soudure en acier, étirés à froid, de section circulaire, utilisés dans les circuits hydrauliques et pneumatiques et de diamètre extérieur spécifié inférieur ou égal à 80 mm..
Les tubes conformes à la présente partie de l'EN 10305 se caractérisent par des tolérances dimensionnelles précises et par une rugosité maximale spécifiée.
Les taux de pression et les températures autorisés relèvent de la responsabilité du client conformément aux règles de l'art et en application des coefficients de sécurité spécifiés dans les réglementations, codes ou normes applicables. En ce qui concerne l’application dans les plages de températures basses, les exigences d’énergie de rupture en flexion par choc sont données à 0° C.
NOTE Lorsque cette norme sera publiée dans le Journal Officiel de l’Union Européenne (JOUE) sous la Directive 97/23/CE, la présomption de conformité aux exigences essentielles de sécurité (EES) est limitée aux données techniques concernant les matériaux, et ne présume pas de l’adéquation du matériau avec un item particulier de l’équipement. En conséquence, la vérification des données techniques figurant dans la norme au regard des exigences de conception applicables à cet item particulier de l’équipement, pour vérifier que les EES de la Directive Equipements sous Pression, doit être faite.
