盐雾试验

       盐雾试验是一种主要利用盐雾试验设备所创造的人工模拟盐雾环境条件来考核产品或金属材料耐腐蚀性能的环境试验，它与天然环境相比，其盐雾环境的氯化物的盐浓度，可以是一般天然环境盐雾含量的几倍或几十倍，使腐蚀速度大大提高，对产品进行盐雾试验，得出结果的时间也大大缩短。盐盐雾试验方法有：中性盐雾（NSS）试验、醋酸盐雾（ASS）试验、铜加速的醋酸盐雾（CASS）试验等。

标准名称：Corrosion tests in artificial atmospheres-Salt spray tests
标准编号：ISO 9227:2012
标准概述：Salt spray tests are generally suitable as corrosion protection tests for rapid analysis for discontinuties, pores and damage in organic and inorganic coatings.In addition, for quality control purpose, comparison can be made between specimens coated with the same coating. As comparative tests; however, salt spray tests are only suitable if the coatings are sufficiently similar in nature.It is often not possible to use results gained from salt spray testing as a comparative guide to the long-term behaviour of different coating systems, since the corrosion stress during these tests differs significantly from the corrosion stresses encountered in practice.
