There are several types of tests to determine exact type of corrosion resistance property of any material. Some of the examples are resistance to Hydrogen Sulphide H2S cracking such as Sulphide stress cracking (SSC) , Stress oriented Hydrogen Induced Cracking (SOHIC), Hydrogen Induced Cracking (HIC), Step Wise Cracking (SWC), Soft Zone Cracking (SZC) etc. The tests are performed in accordance with ISO 15156 NACE MR0175.

Before these tests can be commenced, information such as material type/grade, shape, final form, field H2S pressure, pH values or client’s specification such as Region 1, 2 or 3 is required.
