scope:

This standard specifies the tolerances on dimensions and formfor aluminium and aluminium alloy extruded porthole tubes with anoutside diameter (OD) from 8 mm to 450 mm (round tube, see Figure1) 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 toextruded porthole tube for general engineering applications made inthe following alloys: ? EN AW-1050A, EN AW-1200, EN AW-1350; ? ENAW-3003, EN AW-3103; ? EN AW-5005, EN AW-5005A, EN AW-5049, ENAW-5051A, EN AW-5251, EN AW-5052; ? EN AW-6101A, EN AW-6101B, ENAW-6005, EN AW-6005A, EN AW-6008, EN AW-6110A, EN AW-6012, ENAW-6014, EN AW-6018, EN AW-6351, EN AW-6060, EN AW-6360, ENAW-6061, EN AW-6261, EN AW-6262, EN AW-6262A, EN AW-6063, ENAW-6063A, EN AW-6463, EN AW-6065, EN AW-6081, EN AW-6082; ENAW-6182; ? EN AW-7003, EN AW-7005, EN AW-7108, EN AW-7108A, ENAW-7020. The temper designations used in this part are according toEN 515. This standard only applies to tube produced by the tubeporthole/bridge method. This standard does not apply to: ? extrudedtubes produced by the seamless, die/mandrel method (EN 755-7), ?tubes delivered in coils (EN 13957), ? coiled tubes cut to length(EN 13957).
