This document specifies an accelerated test method for determining the susceptibility to intergranular corrosion of austenitic stainless steel. This document applies to the testing of a variety of metal products, including double rolled metal, welded joints, deposited metal, and weld metal. Note 1: The results obtained by this method are the same as those obtained by the methods in the ISO 3651-1 and ISO 3651-2 standards, but the accelerated corrosion test cycle is shorter. Note 2: This document specifies two test methods: --- Method A: Corrosion test in copper sulfate and concentrated sulfuric acid solutions in the presence of metallic copper; --- Method B: Corrosion test in copper sulfate, sulfuric acid, and copper fluoride solutions in the presence of metallic copper.
