This part of EN 754 specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn porthole 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 thane round tube, see figure 2), supplied in straight lengths. This standard only applies to tube produced by the porthole/bridge method of extrusion only (and then cold drawn to the final dimensions required).
