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.

通用汽车4465P

湿度测试(通用汽车)

通过将涂层试样暴露在高温下的水雾中,可用于测试涂层试样,使用类似于ASTM B117盐雾测试的设备。

将试样放置在符合ASTM B117设备要求的封闭室中。 在这里,它们暴露于连续的间接喷雾水中,该喷雾水以1.0至2.0ml / 80cm² /小时的速率落在样品上,在+38C的腔室温度和100%RH的湿度下。 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。
