entre 2 mm et 50 mm inclus, fournis en couronnes ou en longueurs droites découpées dans des couronnes
(voir la Figure 1).
La présente Norme européenne s’applique principalement aux tubes ronds étirés à froid destinés à des
applications mécaniques générales, en aluminium de la série 1xxx et en alliages de la série 3xxx. Son
application à de l’aluminium non normalisé de la série 1xxx et à des alliages non normalisés de la série 3xxxx
ou à des alliages d’autres séries (par exemple 5xxx ou 6xxx) est soumise à accord entre le fournisseur et
l’acheteur.
La présente Norme européenne s’applique uniquement :
- aux tubes ronds filés à pont, sur filière à pont ou porthole, fournis en couronnes puis étirés à froid
jusqu’aux dimensions finales requises ;
- aux tubes conformes à ce qui précède mais livrés en longueurs droites découpées dans des couronnes.
La présente Norme européenne ne s’applique pas :
- aux tubes filés sans soudure (sur aiguille) et étirés (EN 754-7) ;
- aux tubes filés en longueurs droites (c’est à dire pas en couronnes) et étirés (EN 754-8).

Overview
EN 13958:2008 - Aluminium and aluminium alloys - Cold drawn, round, coiled tube for general applications is a CEN European Standard that specifies tolerances on dimensions and form for round aluminium tubes extruded by the porthole/bridge method, cold drawn to final size and supplied in coil form or as straight lengths cut from coil. It covers tubes with an outside diameter (OD) > 2 mm up to and including 50 mm, primarily for general engineering use in the 1xxx and 3xxx aluminium alloy series. The standard clarifies which products are in scope and explicitly excludes seamless mandrel-extruded tubes (EN 754-7) and straight-extruded drawn tubes (EN 754-8).
Key topics and technical requirements
- Scope & product type: Porthole/bridge extruded, cold drawn round tubes supplied in coils or cut straight lengths. Applies mainly to standard 1xxx and 3xxx alloys; use for other alloys requires agreement.
- Dimensional tolerances: Limits for OD/ID, mean diameter, and ovality; examples and maximum allowable deviations are provided for ODs up to 50 mm.
- Wall thickness & eccentricity: Definitions for mean wall thickness and wall thickness variation (eccentricity); methods and tolerances for measuring eccentricity are explained (see Annex A).
- Form tolerances: Requirements for straightness, squareness of cut ends, and cut-end quality.
- Surface quality: Defines “normal quality” and provisions for stricter inspection (e.g., eddy current, leak testing), lubrication, and handling to prevent fretting or surface damage.
- Coil characteristics: Specification of coil inner/outer diameters, width/height, weight limits, drum/bobbin dimensions, and winding type (random or level winding).
- Ordering information: Buyers must supply product form, reference to related standards (EN 573-3 for chemistry, EN 515 for temper, EN 754-2 for mechanical properties), and only two of OD/ID/wall thickness when ordering.
- Quality control & testing: Supplier responsibility for inspections and tests per the standard or specific order agreements.
Applications and users
- Intended for manufacturers, procurers, quality engineers, and design engineers in the engineering and manufacturing sectors who require consistent dimensional and form tolerances for cold drawn aluminium tube supplied in coils.
- Practical uses include any general engineering application needing reliable OD/ID control, predictable wall thickness, and form tolerance for downstream processes (decoiling, straightening, cutting).
