This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded seamless 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. This standard only applies to tube produced by the seamless die/mandrel method of extrusion. This standard applies to extruded seamless tube for general engineering applications only. This European Standard does not apply to: extruded tubes produces by 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 Clause 2: Alloys EN AW-3102, EN AW-6008, EN AW-6014, EN AW-6360 are added in Group Alloys EN AW-5049, EN AW-6110A, EN AW-6023, EN AW-7108, EN AW-7108A and EN added in Group II Subclauses 3.4 and Table 4: Requirements to wall thickness variation (eccentricity) is introduced Annex A: Informative Annex A is added explaining wall thickness variation (eccentricity).
