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.

ASTM G85 附录 A5

稀电解质循环雾/干法试验

可用于测试钢上涂料的相对耐腐蚀性,当暴露于环境温度下稀盐雾的变化气候时,随后在高温下进行空气干燥和高温。

将试样放置在封闭的腔室中,并暴露于由以下2部分重复循环组成的气候变化中。 暴露于连续间接喷洒稀酸化(pH 5.0至5.4)盐水溶液1.0小时,该溶液在环境室温度(21至27C)下以1.0至2.0ml / 80cm² /小时的速率落到样品上。 随后在+35C的腔室温度下暴露于空气干燥(吹扫)气候1.0小时。 重复周期的次数,因此测试持续时间是可变的。

该测试也称为粘附测试。
