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.

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。

NFT 30-077测试标准规定了确定漆膜,油漆系统和相关产品对高湿度条件的抵抗力的方法。 该方法既适用于多孔基材(如木材、石膏和石膏板)上的涂料,也适用于金属等无孔基材上的涂料。 它表明了在恶劣暴露条件下以及表面上发生连续冷凝时可能获得的性能。 该过程可能显示涂层缺陷(包括起泡,染色,软化,压接,脆化)和基材的劣化。 它还确定灰分含量。
