适用范围：This document specifies the tolerances on dimensions and form for aluminium and aluminium alloy extrudedseamless tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube, see Figure 1) or with across section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, seeFigure 2), supplied in straight lengths.This standard only applies to tube produced by the seamless die/mandrel method of extrusion. This standardapplies to extruded seamless tube for general engineering applications only.The temper designations used in this part are according to EN 515.This European Standard does not apply to: extruded tubes produced by porthole/bridge method (EN 755-8), tubes delivered in coils (prEN 13957), coiled tubes cut to length (prEN 13957).Figure 1 — Round tubeFigure 2 — Circumscribing circle for other than round tube
