The document specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded porthole tubes with an outside diameter (OD) from 8 mm to 350 mm (round tube) or with a cross section contained withing a circumscribing circle (CD) from 10 mm to 450 mm (other than round tube), supplied in straight lengths. It applies to extruded porthole tube for general engineering applications made in the alloys, which are given in the document. It only applies to tube produced by the tube porthole/bridge method.
