Aluminium and aluminium alloys. Cold drawn rod/bar and tube -- Porthole tubes, tolerances on dimensions and form
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).
