Aluminium and aluminium alloys. Extruded rod/bar, tube and profiles -- 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 ENÂ 515 .
This European Standard does not apply to:
extruded tubes produced by porthole/bridge method ( EN 755‑8 ),
tubes delivered in coils ( ENÂ 13957 ),
coiled tubes cut to length ( ENÂ 13957 ).
