Case histories and laboratory test data are presented to compare the predictive utility of NACE MR0175 with three alternatives. With some exceptions, the MR0175 definition is useful and conservative for most cases. The definition based on water phase pH and hydrogen sulfide (H{sub 2}S) partial pressure, proposed in European Federation of Corrosion (EFC) pub. 16, is not recommended since it does not predict sulfide stress cracking (SSC) in refining environments and presents higher risk of SSC of sweet service materials in certain Arabian Gulf production environments. A modified definition of sour service is proposed, which uses the MR0175 definition except in cases of very low water phase pH. 47 refs., 4 figs., 1 tab.
