This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded seamless tubes with an outside diameter from 8 mm to 450 mm or with a cross section contained within a circumscribing circle from 10 mm to 350 mm. 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) or coiled tubes cut to length (EN 13957). This European Standard has been prepared by CEN/TC 132/WG 5 "Extruded and drawn products" (secretariat: SN, Norway). On the national level DIN Working Committee NA 066-01-04 AA "Strangpresserzeugnisse" ("Extruded products") at FNNE is responsible for this standard.
