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.
Tubes according to this document are characterized 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.
NOTE Once this 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 standard and does not presume adequacy of the material to a specific item of equipment.

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.
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 2014/68/UE , la présomption de conformité aux exigences essentielles de sécurité (EES) de la directive 2014/68/UE 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 ce composant particulier de l’équipement, pour vérifier que les EES de la Directive Equipements sous Pression, doit être faite.
Jeklene cevi za precizno uporabo - Tehnični dobavni pogoji - 4. del: Hladno vlečene nevarjene cevi za hidravlične in pnevmatične tlačne vode
Ta evropski standard določa tehnične dobavne pogoje za hladno vlečene nevarjene cevi s krožnim prečnim prerezom za hidravlične in pnevmatične tlačne vode.
Cevi v skladu s tem dokumentom imajo natančno opredeljene tolerance za mere in določeno največjo površinsko hrapavost.
Za dovoljene ravni tlaka in najvišje temperature je odgovorna stranka v skladu s stanjem tehnike in ob uporabi varnostnih koeficientov, določenih v veljavnih predpisih, kodeksih ali standardih. Kar zadeva ustreznost razpona nižjih temperatur, so zahteve glede udarne moči podane pri 0° C.
OPOMBA: Ko bo ta standard objavljen v Uradnem listu Evropske unije (OJEU) v okviru Direktive 97/23/ES, bodo zagotovila o skladnosti z osnovnimi varnostnimi zahtevami (ESR) Direktive 97/23/ES omejena na tehnične podatke o materialih, navedene v tem evropskem standardu, standard pa ne bo zagotavljal ustreznosti materiala za določen element opreme. Zato bo potrebno oceniti tehnične podatke, podane v tem standardu za materiale, glede na zahteve zasnove določenega elementa opreme, da se zagotovi, da so izpolnjene osnovne varnostne zahteve Direktive o tlačni opremi.
