Aluminiu şi aliaje de aluminiu. Bare şi ţevi trase la rece. Partea 7: Ţevi fără sudură, toleranţe la dimensiuni şi de formă
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). The temper designations used in this part are according to EN 515. 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 (EN 754-8), - tubes delivered in coils (EN 13958), - coiled tubes cut to length (EN 13958).
