This part of EN 754 specifies the tolerances on dimensions and form for aluminium and aluminium alloy 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 applies only to tube produced by the seamless die/mandrel method of extrusion (and then cold drawn to the final dimensions required).
This standard applies to cold drawn, seamless tube for general engineering applications.
This standard does not apply to extruded, cold drawn tube produced by the porthole/bridge method or to coiled tube.
