 【摘要】  1.1 This International Standard specifies the meth- ods of integranular corrosion testing for solution heat-treatable aluminium alloys without protectivecoatings.The sensitivity of solution heat-treatable aluminiumalloys to intergranular corrosion is a function of thealJoy chemical composition, method of manufacturing,solution heat treatment, quench treatment and arti-ficial precipitation hardening (ageing) treatment.In the naturally aged condition, the sensitivity of sol-ution heat-treatable aluminium alloys to intergranularcorrosion is a function primarily of the rate of coolingduring quenching over a critical temperature range.1.2 This International Standard is applicable to castand wrought heat-treatable atuminium alloys in theform of castings, forgings, plates, sheets, extrusionsand semi-finished or finished parts, in order to carryout comparative assessment of alloys of differentgrades and thickness depending on their chemicalcomposition and other factors, and also to check thethermal processing quality of the tested materials.The test results provide information to determine theintergranular corrosion resistance and thermal pro-cessing quality of the tested materials.1.3 The test results cannot be regarded as absolute,because they are not applicable to all environmentsthat can be met in service. They are best used m arelative manner, to compare the intergranular cor-rosion resistance of various heats of solution heat-treatable aluminium alloys.
