ISO 15329:2006规定了一种电化学方法，用于测定溶液热处理铝合金（即2XXX、6XXX、7XXX和8XXX合金）在各种老化条件下的晶间腐蚀敏感性，无保护涂层。 ISO 15329:2006适用于铸件、锻件、板材、板材、挤压件和半成品或成品零件形式的铸造和锻造热处理铝合金，以便根据其化学成分和其他因素对不同等级和厚度的合金进行比较评估，并检查被测材料的热加工质量。试验结果提供的信息有助于确定受试材料的晶间耐蚀性和热处理质量（见第8条和第9条）。

ISO 15329:2006 specifies an electrochemical method to determine susceptibility to intergranular corrosion of solution-heat-treatable aluminium alloys, that is 2XXX, 6XXX, 7XXX and 8XXX alloys, without protective coatings and in various ageing conditions. ISO 15329:2006 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 a 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 materials. The test results provide information to help to determine the intergranular corrosion resistance and thermal processing quality of the tested materials (see Clauses 8 and 9).
