Corrosion Testing Standards

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.




将试样置于封闭的腔室中,并暴露于由以下两部分重复循环组成的气候变化中。 连续间接喷洒酸化(pH 2.8至3.0)合成海水溶液30分钟,该溶液以1.0至2.0ml / 80cm² /小时的速率落在样品上。 接下来是90分钟暴露在高于98%RH的高湿度气候下。 整个测试周期在+49°C的恒定腔室温度下进行(对于有机涂层试样,可降至+24至+35°C)。 重复周期的次数,因此测试持续时间是可变的。

此测试也称为 SWAAT 测试。


注意;ASTM G43 已被 ASTM G85 附录 A3 取代
