Resumen:

This European Standard 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 European 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 ).
