标准摘要
[中文适用范围]： 本国际标准规定了测定奥氏体不锈钢晶间腐蚀敏感性的加速方法。标准规定的方法提供的结果与使用 ISO 3651-1 和 ISO 3651-2 时获得的结果相同，但加速腐蚀试验的周期更短。本国际标准适用于各种金属产品的测试，包括双层轧制金属、焊接接头、沉积金属和焊缝金属。规定了两种试验方法：方法 A：在含有金属铜的硫酸铜和浓硫酸溶液中进行腐蚀试验；方法 B：在含有金属铜的硫酸铜、硫酸和氟化铜溶液中进行腐蚀试验。 [外文原描述]： ISO 21610:2009 specifies accelerated methods for the determination of the intergranular corrosion susceptibility of austenitic stainless steels. The methods specified by the standard provide results identical to those obtained when using ISO 3651‑1 and ISO 3651‑2, but the test period for the accelerated corrosion test is shorter. The standard is applicable to the testing of various kinds of metal production, including two-layer rolled metal, welded joints, deposited metal and weld seam metal. Two test methods are specified: method A: corrosion test in a solution of copper sulfate and concentrated sulfuric acid in the presence of metallic copper; method B: corrosion test in a solution of copper sulfate, sulfuric acid and copper fluoride in the presence of metallic copper.
