This standard specifies the general tolerances of:
Extruded section
in aluminium alloys
for aerospace applications.
It applies:
- to sections, standardized or defined by a drawing, the cross section of which, regular or irregular, can be inscribed in a circle of 250 mm (see figure 1),
- to semi-hollow sections, the dimensional limits of which are indicated in figures 2 and 3.
For sections with higher dimensions or of more complex forms, the tolerances shall be subject to agreement between the manufacturer and purchaser.
