Scope

This document specifies the terminology and definitions, principles, test conditions, reagents and materials, specimens, test procedures, and data processing for the hydrogen-induced cracking sensitivity test method of pipeline materials under the combined effects of slow strain rate loading, soil corrosion, and hydrogen environment. This document is applicable to buried pipeline materials such as oil, natural gas, and hydrogen, which are evaluated for their cracking performance under corrosion and hydrogen coupling conditions by using hollow rod specimens immersed in soil solution and subjected to hydrogen environment in the center, and assessed through slow strain rate tensile testing methods under actual service conditions (stress, soil corrosion, and hydrogen environment).
