In continuation of previous work environmental and materials related parameters were studied influencing the SOHIC suseeptlhilityof linepipe steel. Steels according to API classification Grade 42 mainly differing in sulfir content and microstructure were tested with respect to the type and geometry of specimens (unnotched and notched 4-point bent and double beam specimens; compact and hollow tensile probes), type of media (NACE TMO177-96/Solution A; water-rich TEG pipeline fluid; low chloride water), hydrogen sulfide partial pressure (0.1 and 1.6 MPa), and exposure mode (submerged in and filmed with the corrosive liquid). The results are used to recommend predictive experimental procedures to test and investigate the SOHIC susceptibility of steels. Experiments with hollow tensile probes allow hydrogen permeation measurements under mechanical loading and corrosive conditions. They proved to be a useful tool to investigate environmental parameters affecting hydrogen embrittlement of steel, to quantify the hydrogen uptake, and to define critical conditions for SOHIC. Keywords: Corrosion, carbon steel, linepipe steel, hydrogeu stress cracking, stress oriented hydrogen induced cracking, SOHIC, hydrogen sulfide, hydrogen permeation
