This European Standard 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 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 tubes produced by the seamless, die/mandrel method ( EN 754‑7),
tubes delivered in coils ( EN 13958),
coiled tubes cut to length ( EN 13958).
