实验室浸泡试验和电化学试验时研究缝隙腐蚀的重要方法。对于浸泡试验法，设计型式多样的人造缝隙，采用多种腐蚀介质，一般以腐蚀质量或腐蚀深度评定试验结果；电化学测试方法是以某些电化学参数作为判据，来比较金属材料对缝隙腐蚀的相对敏感性，一般来说，电化学测试方式可缩短缝隙腐蚀的诱导期而达到加速腐蚀试验的目的。浸泡试验法包括三氯化铁实验、缝隙腐蚀的加速试验方法、多缝隙腐蚀试验、MTI试验、临界缝隙腐蚀温度法等；电化学测试方法包括ASTM标准试验方法、恒电位试验、动电位极化试验法、远距离缝隙装置试验等。

标准名称：Standard Test Method for Electrochemical Critical Pitting Temperature Testing of Stainless Steels
标准编号：ASTM G150–99
标准概述：This test method covers a procedure for the evaluation of the resistance of stainless steel and related alloys to pitting corrosion based on the concept of the determination of a potential independent critical pitting temperature （CPT）。This test methods applies to wrought and cast products including but not restricted to plate, sheet, tubing, bar, forgings, and welds.The standard parameters recommended in this test method are suitable for characterizing the CPT of austenitic stainless steels and other related alloys with a corrosion resistance ranging from that corresponding to solution annealed UNS S31600 （Type 316 stainless steel） to solution annealed UNS S31254 （6 % Mo stainless steel）。

标准名称：Standard Test Method for Electrochemical Critical Pitting Temperature Testing of Stainless Steels
标准编号：ASTM G61-86（2009）
标准概述：This test method covers a procedure for conducting cyclic potentiodynamic polarization measurements to determine relative susceptibility to localized corrosion （pitting and crevice corrosion） for iron-, nickel-, or cobalt-based alloys in a chloride environment. This test method also describes an experimental procedure which can be used to check one's experimental technique and instrumentation.
