标准摘要
[中文适用范围]： 本国际标准规定了铝合金抗应力腐蚀开裂（SCC）性能的测定方法。 2 本国际标准涵盖了取样方法、样本类型、装载程序、环境类型和结果解释。 3 本国际标准旨在确定作为铝合金化学成分、制造方法和热处理函数的抗应力腐蚀开裂性。 4 本国际标准适用于铸件、半成品、零件和焊件形式的铸造和变形铝合金。 5 由于大多数自然和许多人工环境都含有氯化物，因此本国际标准可用于比较在海洋大气和含有氯化物的环境中使用的产品的性能，前提是故障机制不改变。 然而，该测试的结果不应被视为合金质量的绝对标准。 [外文原描述]： ISO 9591:2004 specifies a method for the determination of resistance to stress corrosion cracking (SCC) of aluminium alloys. It covers the method of sampling, the types of specimens, the loading procedure, the type of environment and the interpretation of results. This International Standard is aimed at determining resistance to SCC as a function of the chemical composition, the method of manufacture and heat treatment of aluminium alloys. It applies to cast and wrought aluminium alloys in the form of castings, semi-finished products, parts and weldments. Since most natural and many artificial environments contain chlorides, ISO 9591:2004 can be used to compare the performance of products employed under marine atmospheres and in environments containing chlorides, providing that the failure mechanism is not changed.
