This document specifies the chemical composition limits of wrought aluminium and wrought aluminium alloys and form of products. NOTE The chemical composition limits of aluminium and aluminium alloys specified herein are completely identical with those registered with the Aluminium Association, 1525, Wilson Boulevard, Suite 600, Arlington, VA 22209, USA, for the corresponding alloys.

This document specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded porthole tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, see Figure 2), supplied in straight lengths. The temper designations used in this part are according to EN 515. This document only applies to tube produced by the tube porthole/bridge method. This document does not apply to: — extruded tubes produced by the seamless, die/mandrel method (EN 755-7); — tubes delivered in coils (EN 13957); — coiled tubes cut to length (EN 13957).
