DIN EN 754-8:2016-10

This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn porthole tubes with an outside diameter from 3 mm to 350 mm (round tube) or with a cross section contained within a circumscribing circle from 8 mm to 300 mm (other than round tube), supplied in straight lengths. This document only applies to cold drawn tube for general engineering applications. The temper designations used in this part are according to EN 515. This document only applies to tube produced by the porthole/bridge method of extrusion only (and then cold drawn to the final dimensions). This document does not apply to cold drawn tube produced by the seamless, die/mandrel method (EN 754-7), tubes delivered in coils (EN 13958) or coiled tubes cut to length (EN 13958). This European Standard has been prepared by CEN/TC 132/WG 5 "Extruded and drawn products" (secretariat: SN, Norway). On the national level Working Committee NA 066-01-04 AA "Strangpresserzeugnisse" ("Extruded products") at DIN Standards Committee Nonferrous Metals (FNNE) is responsible for this standard.
