DIN EN 755-8:2016-10

This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded porthole tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube), supplied in straight lengths. This standard only applies to extruded porthole tube for general engineering applications and manufactured from specified materials. The temper designations used in this part are according to EN 515. This European Standard does not apply to extruded tubes produced by the seamless, die/mandrel method (EN 755-7), 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.
