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.
DIN 50 021-ESS
醋酸盐雾试验
可用于测试涂料在高温下暴露于乙酸盐雾气候时的相对耐腐蚀性。
将测试样品置于封闭的腔室中，并暴露于酸化（pH 3.1至3.3）盐水溶液的连续间接喷雾中，该溶液以1.0至2.0ml / 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。
