scope:

Specifies the methods of intergranular corrosion testing for solution heat-treatable aluminium alloys without protective coatings. The standard is applicable to cast and wrought heat-treatable aluminium alloys in the form of castings, forgings, plates, sheets, extrusions and semi-finished or finished parts, in order to carry out comparative assessment of alloys of different grades and thickness depending on their chemical composition and other factors, and also to check the thermal procssing quality of the tested materials.
