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.

国际标准化组织 ISO 3768

金属涂层的腐蚀测试 – 中性盐雾测试


将试样置于封闭的腔室中,并暴露于连续间接喷洒中性(pH 6.5至7.2)盐水溶液,该溶液以1.0至2.0ml / 80cm² /小时的速率在+35C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。


此测试也称为 NSS 测试。


注意;ISO 3768 已被 ISO 9227 取代。
