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.

BS 7479

人造大气中的盐雾腐蚀测试

可用于测试金属材料的相对耐腐蚀性,有或没有临时或永久的腐蚀保护,当暴露于盐雾气候(中性盐雾或乙酸盐雾或铜加速乙酸盐雾)在高温下。

将试样置于封闭的腔室中,并暴露于中性(pH 6.5至7.2)或酸化(pH3.1至3.3)盐水溶液的连续间接喷雾中,该盐水溶液以1.0至2.0ml / 80cm² /小时的速率在+35C或+50C的腔室温度下落到试样上。 这种气候在恒定的稳态条件下保持。 测试持续时间是可变的。

该标准已被ISO 9227取代。

这些测试也称为NSS,ASS和CASS测试。
