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.

VDA 233-102


该测试的目的是为评估部件的腐蚀行为和涂层系统提供的腐蚀保护提供加速的测试程序。 该测试方法基于真实的腐蚀条件,可为汽车应用中的大量用途提供差异化的结果

将试样放置在封闭的腔室中,并以65°至75°的角度定位为水平方向,待测的一侧位于最上方。 盐雾阶段用1%氯化钠溶液(pH 6.5至7.1)进行,并以2.0至4.0ml / 80cm² /小时的速率落到样品上。


循环A,B和C是多步循环,包括从-15°C到+ 50°C的不同温度和50%到95%之间的湿度值。

典型的测试持续时间为六个完整的测试周期。 (6 周)
