This document specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn porthole tubes with an outside diameter (OD) from 3 mm to 350 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 8 mm to 300 mm (other than round tube, see Figure 2), supplied in straight lengths.This document only applies to cold drawn tube for general engineering applications made in the following alloys: EN AW-1050A, EN AW-1200; EN AW-3003, EN AW-3103; EN AW-5005, EN AW-5005A, EN AW-5049, EN AW-5251, EN AW-5052; EN AW-6012, EN AW-6060, EN AW-6061, EN AW-6262, EN AW-6262A; EN AW-6063, EN AW-6063A, EN AW-6065, EN AW-6082; EN AW-7020. The temper designations used inThis 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 tubes produced by the seamless, die/mandrel method (EN 754-7), tubes delivered in coils (EN 13958), coiled tubes cut to length (EN 13958).
