The test standard summaries are for general guidance only. Though believed to be accurate at the time of writing, this may change over time. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.
Note: the terms salt spray, salt mist and salt fog are all in wide spread use within corrosion test standards. In this context they can be considered to be equivalent and interchangeable terms.

通过交替浸泡在中性3.5%氯化钠溶液中暴露金属和合金的标准做法。
该标准涵盖了在3.5%氯化钠中进行交替浸入应力腐蚀测试的程序,主要用于铝合金和黑色合金的测试,但可能用于对氯离子敏感的其他金属。
该测试采用1小时的周期,其中包括在3.5%氯化钠水溶液中10分钟,然后在溶液中取出50分钟,在此期间允许样品干燥。 这个1小时的周期在为被测试的特定合金推荐的总天数内持续24小时/天,通常为20至90天或更长时间,具体取决于合金对盐水腐蚀的抵抗力
