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.

环境法 ISO 7253

油漆和清漆 – 对中性盐雾(雾)的抵抗力的测定

可用于测试油漆和清漆在高温下暴露于盐雾(雾)气候时的相对耐腐蚀性。

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2.5ml / 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。

本测试标准不允许腔室容积小于400升。

该测试也称为中性盐雾或NSS测试。
