There were different standards about intergranular corrosion test in weld joint of austenittic stainless steel in different industies and countries, including sensitizing treatment regime,location and ori- entation of sampling, demision of sample, choice of bending diameter and bending angle. Besides, the con- tents of some standards were obscure. So many disputes appear in project application, Based on the princi- ple and destination of intergranular corrosion test. the possibility of unify the requirement of different standards wads discussed.不同国家和行业针对奥氏体不锈钢的晶间腐蚀试验制定了不同的标准。在晶间腐蚀试验的敏化制度、取样部位和方向、试样的尺寸、弯曲试验压头直径的选择、弯曲角度等方面，不同标准之间存在差异。此外，有些标准的规定不是很明确，造成理解上的分歧，在工程实际应用中引起不必要的争议。分析了不同标准之间的差异，结合晶间腐蚀试验的原理和目的，在达到考核材料耐晶间腐蚀性能的前提下，探讨统一相关标准要求的可能性。
