ISO 3651-2:1998 Determination of resistance to intergranular corrosion of stainless steels - Part 2: Ferritic,austenitic and ferritic-austenitic (duplex) stainless steels - Corrosion test in media containing sulfuric acid
standard by International Organization for Standardization, 05/01/1998

Full Description
This part of ISO 3651 specifies methods for the determination of the resistance to intergranular corrosion of ferritic, austenitic and ferritic-austenitic (duplex) stainless steels in media containing sulfuric acid. It also specifies the purposes which may be assigned to the test. The test methods included are:
method A: the 16 % sulfuric acid/copper sulfate test (Monypenny Strauss test);method B: the 35 % sulfuric acid/copper sulfate test;method C: the 40 % sulfuric acid/ferric sulfate test.The methods are applicable to stainless steels supplied in the form of cast, rolled or forged products and tubes and intended for use in a mildly oxidizing acid medium (for example, sulfuric acid, phosphoric acid).
Unless specified in the product standard, the method to be used, A, B or C, shall form the subject of an agreement between the interested parties.
Annex A gives examples of application of the three methods on stainless steels.
