Aluminium and aluminium alloys - Extruded rod/bar, tube and profiles - Part 7: Seamless tubes, tolerances on dimensions and form

This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded seamless tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, see Figure 2), supplied in straight lengths.
This European Standard only applies to tube produced by the seamless die/mandrel method of extrusion. This standard applies to extruded seamless tube for general engineering applications only.
The temper designations used in this part are according to EN 515.
This European Standard does not apply to:
-   extruded tubes produced by porthole/bridge method (EN 755-8),
-   tubes delivered in coils (EN 13957),
-   coiled tubes cut to length (EN 13957).

Diese Europäische Norm legt die Grenzabmaße und Formtoleranzen für stranggepresste nahtlose Rohre aus Alu¬minium und Aluminiumlegierungen mit einem Außendurchmesser (OD) (en: outside diameter) von 8 mm bis 450 mm (Rundrohre, siehe Bild 1) oder mit einem Querschnitt, der in einem Umschlingungskreis (CD) (en: circumscribing circle) von 10 mm bis 350 mm enthalten ist (andere als Rundrohre, siehe Bild 2) fest, geliefert in geraden Längen.
Diese Europäische Norm gilt nur für Rohre, die nach dem nahtlosen Strangpressverfahren hergestellt werden. Diese Norm gilt nur für stranggepresste nahtlose Rohre für allgemeine Anwendungen.
Die in diesem Dokument verwendeten Bezeichnungen der Werkstoffzustände entsprechen EN 515.
Diese Europäische Norm gilt nicht für:
—   Rohre, die nach dem Strangpressverfahren mit Kammer /Brückenwerkzeug hergestellt werden (EN 755-8);
—   Rohre, die in Ringen geliefert werden (EN 13957);
—   Rohre in Ringen, die auf Länge geschnitten werden (EN 13957).

Aluminium et alliages d'aluminium - Barres, tubes et profilés filés - Partie 7 : Tubes filés sur aiguille, tolérances sur dimensions et forme

La présente Norme européenne spécifie les tolérances sur dimensions et forme des tubes filés sur aiguille en aluminium et alliages d’aluminium avec un diamètre extérieur (OD) de 8 mm à 450 mm (tube rond, voir la Figure 1) ou avec une section transversale contenue dans le cercle circonscrit (CD) de 10 mm à 350 mm (autre que tube rond, voir la Figure 2), fournis en longueurs droites.
La présente Norme européenne ne s’applique qu’aux tubes produits à l’aide d’une méthode de filage sans soudure/sur aiguille. Le présent document s’applique aux tubes filés sur aiguille pour applications générales uniquement.
La désignation des états métallurgiques utilisés dans cette partie est conforme à l’EN 515.
La présente Norme européenne ne s’applique pas :
-   aux tubes filés produits à l’aide d’une méthode de filage à pont (EN 755-8) ;
-   aux tubes livrés en couronnes (EN 13957) ;
-   aux tubes en couronnes découpés à longueur (EN 13957).

Aluminij in aluminijeve zlitine - Iztiskane palice/drogovi, cevi in profili - 7. del: Nevarjene (narejene iz celega) cevi, tolerance mer in oblike

Ta evropski standard določa tolerance mer in oblike za iztiskane nevarjene cevi iz aluminija in aluminijeve zlitine z zunanjim premerom (OD) od 8 mm do 450 mm (okrogla cev, glej sliko 1) ali s presekom v odprtini (CD) velikosti od 10 mm do 350 mm (neokrogla cev, glej sliko 2), dobavljene v ravnih presekih.
Ta evropski standard se uporablja samo za cevi, izdelane z metodo iztiskovanja s celim utopom/trnom. Ta standard se uporablja samo za iztiskane nevarjene cevi za splošno tehnično uporabo.
Oznake za popuščanje, uporabljene v tem delu, so skladne s standardom EN 515.
Ta evropski standard se ne uporablja za:
– cevi, izdelane z metodo iztiskovanja z večdelnimi matricami/mostičkom (EN 755-8),
– cevi, dobavljene v navojih (EN 13957),
– navojne cevi, razrezane po dolžini (EN 13957).
