scope:

This standard specifies the tolerances on dimensions and formfor aluminium and aluminium alloy cold drawn porthole tubes with anoutside diameter (OD) from 3 mm to 350 mm (round tube, see Figure1) 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 colddrawn tube for general engineering applications made in thefollowing alloys: ? EN AW-1050A, EN AW-1200; ? EN AW-3003, ENAW-3103; ? EN AW-5005, EN AW-5005A, EN AW-5049, EN AW-5251, ENAW-5052; ? EN AW-6012, EN AW-6060, EN AW-6061, EN AW-6262, ENAW-6262A; ? EN AW-6063, EN AW-6063A, EN AW-6065, EN AW-6082; ? ENAW-7020. The temper designations used in this part are according toEN 515. This document only applies to tube produced by theporthole/bridge method of extrusion only (and then cold drawn tothe final dimensions). This document does not apply to: ? colddrawn tubes produced by the seamless, die/mandrel method (EN754-7), ? tubes delivered in coils (EN 13958), ? coiled tubes cutto length (EN 13958).
