scope:

Specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn seamless tubes with an outside diameter (CD) from 3 mm to 350 mm (round tube) or with a cross section contained within a circumscribing circle (CD) from 8 mm to 300 mm (other than round tube) 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). 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.
