NACE TM0111-2011

This standard establishes a SSR test method for evaluating susceptibility of carbon steels to ethanol SCC. It relates to the evaluation of SCC that may be observed in equipment involved in handling, storage, and transportation of ethanolic environments. This equipment primarily includes storage tanks and pipeline system components typically associated with the distribution of ethanolic environments, which includes FGE and FGE-fuel blends. This test method may also be used for research related to the effects of environmental or metallurgical variables on susceptibility to ethanol SCC. Field samples of FGE and FGE-fuel blends present under natural service conditions, as well as synthetic ethanolic solutions prepared in the laboratory, may be used with this test method.
