This International Standard specifies an electrochemical method to determine susceptibility to intergranularcorrosion of solution-heat-treatable aluminium alloys, that is 2XXX, 6XXX, 7XXX and 8XXX alloys, withoutprotective coatings and in various ageing conditions. This International Standard is applicable to cast and wrought heat-treatable aluminium alloys in the form ofcastings, forgings, plates, sheets, extrusions, and semi-finished or finished parts, in order to carry out acomparative assessment of alloys of different grades and thickness depending on their chemical compositionand other factors, and also to check the thermal processing quality of the tested materials. The test resultsprovide information to help to determine the intergranular corrosion resistance and thermal processing qualityof the tested materials (see Clauses 8 and 9). The test results cannot be regarded as absolute, because they are not applicable to all environments that canbe met in service. They are best used in a relative manner, to compare the intergranular corrosion resistance ofvarious heats of solution-heat-treatable aluminium alloys.
