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 3231

Kesternich 测试模拟酸雨或工业化学品暴露,以评估涂层、基材或部件本身的相对耐腐蚀性。 零件或面板放置在专门设计的腔室中,并暴露于SO2和湿度下,然后进行耐腐蚀性评估。 以下标准用于此类测试。

ISO 3231:1993用于验证油漆和清漆。 它决定了对含有二氧化硫(So2)的潮湿气氛的抵抗力。 指定程序的原理是将涂层测试板暴露在含有二氧化硫的特定潮湿气氛中。 在大气压下测量的体积为0.2升,通常建议用于测试厚度不超过约40μm的涂层。 然后根据规定的标准评估暴露的影响。 适用于单涂层薄膜或多涂层涂料体系。
