TM0284-2003 provides a standard set of test conditions for consistent evaluation of pipeline and pressure vessel steels and comparing test results from different laboratories pertaining to the results of the absorption of hydrogen generated by corrosion of steel in wet H2S. Describes two test solutions, Solution A and Solution B, and includes special procedures for testing small-diameter, thin-wall, electric-resistance welded and seamless line pipe. Test in intended to evaluate resistance to hydrogen-induced (stepwise) cracking only, and not other adverse effects of sour environments such as sulfide stress cracking, pitting, or weight loss from corrosion. Complements NACE Standard MR0175.
