This standard specifies the methods of integranular corrosion testing for Solution heat-treatable aluminium alloys without protective coatings. The sensitivity of Solution heat-treatable aluminium alloys to intergranular corrosion is a function of the alloy Chemical composition, method of manufacturing, Solution heat treatment, quench treatment and artificial precipitation hardening (ageing) treatment. In the naturally aged condition, the sensitivity of solution heat-treatable aluminium alloys to intergranular corrosion is a function primarily of the rate of cooling during quenching over a critical temperature range. This 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 processing quality of the tested m
