This standard specifies a test method for evaluating the susceptibility of metallic materials, particularly steels used in the oil and gas industry, to failure due to sulfide stress cracking (SSC) and stress corrosion cracking (SCC) in environments containing hydrogen sulfide (H₂S) under laboratory conditions. The standard outlines procedures for preparing specimens, preparing test solutions with specific H₂S concentrations, applying constant tensile loads (or using pre-cracked bend specimens), and maintaining precise test temperature and pressure. The core instrument for conducting this test is a constant-load tensile testing machine for sulfide stress cracking resistance. The test is typically performed within a sealed test chamber designed to safely contain the toxic H₂S environment, ensuring reproducible results under strictly controlled conditions and providing critical data for material selection and engineering safety.
