Defines the tolerances on dimensions and form for aluminium and aluminium alloys cold drawn seamless tubes with an outside diameter (OD) from 3 mm to 350 mm or with a cross section contained within a circumscribing circle (CD) from 8 mm to 300 mm (other than round tube) supplied in straight Lengths.

This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloys cold drawn seamless tubes with an outside diameter ( OD) from 3mm to 350mm (round tube, see Figure1) or with a cross section contained within a circumscribing circle ( CD) from 8mm to 300mm (other than round tube, see Figure2) supplied in straight lengths. This European Standard only applies to tube produced by the seamless die/mandrel method of extrusion (and then cold drawn to the final dimensions required). The temper designations used in this part are according to EN515 . This document applies to cold drawn, seamless tube for general engineering applications. This document does not apply to: cold drawn tube produced by the porthole/bridge method ( EN754‑8 ), tubes delivered in coils ( EN13958 ), coiled tubes cut to length ( EN13958 ).
