This document specifies 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 (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 standard only applies to tube produced by the seamless die/mandrel method of extrusion (and then cold drawn to the final dimensions required). 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 tubes delivered in coils. coiled tubes cut to length. The following technical modifications have been introduced during the revision: Clause 1: Scope is clarified with respect to what is not included Alloy EN AW-5049, EN AW-6262A and EN AW-6065 are added Clause 2.4 and Table 3: Requirements to wall thickness variation (eccentricity) is introduced Annex A: Informative Annex A is added explaining wall thickness variation (eccentricity).
