摘　　要：介绍了通过腐蚀试验来评价电气、电子产品、装置在使用及储备条件下的耐腐蚀性能,多种低浓度混合气体试验方法的最新的研究现状,ISO、IEC及日本工业标准JIS中的标准腐蚀性气体试验方法。讨论了模拟一般环境下SO2及H2S混合气体的试验条件,对铜试样做含臭氧的高加速混合腐蚀性气体的试验方法。探讨了交流阻抗法应用于腐蚀性气体试验及其影响因素。Corrosive gas tests for evaluation corrosion resistance and reliability of electronic devices in operation and storage are reviewed. Recently many kind of mixed gas tests with low concentration are investigated in some technical committees and adopted in some international standards, such as ISO, IEC, and Japanese industrial standards (JIS). SO2/H2S mixed gas test is suitable for simulating the ordinary environment. The mixed gas test with ozone accelerates the corrosion of copper while simulating the ordinary environment. Impedance measurement results reflect the effect of corrosive gas.
