Corrosion Resistant Alloys for Oil and Gas Production: Guidance on General Requirements and Test Methods for H2S Service, Volume 69, proposes test methods for assessing the environmental cracking resistance of Corrosion Resistant Alloys (CRAs) and provides a standard methodology for establishing the environmental cracking resistance of CRAs in H2S service. This revised volume discusses changes to the procedure for stress loading Bent Beam specimens, C-ring specimens, ISO 15156/NACE MR0175, and associated corrigenda.
