Methods for evaluating material compatibility in high-pressure hydrogen — Screening test method for stainless steel pipes using hole-drilled specimens

This technical specification outlines a standardized procedure for evaluating the compatibility of materials, specifically stainless steel tubes, when exposed to high-pressure hydrogen environments. The method focuses on a screening test approach utilizing drilled samples to assess the performance and integrity of the piping materials under extreme operational conditions. By establishing a uniform protocol, the document provides a framework for identifying potential material failures or degradation mechanisms that may occur during hydrogen storage and transportation. The outlined process ensures consistency in testing practices, allowing various stakeholders to verify material suitability through a defined experimental setup. This approach is designed to facilitate the selection of appropriate stainless steel components for systems where high-pressure hydrogen is utilized, thereby supporting safety and reliability in industrial applications. The methodology details sample preparation, testing parameters, and evaluation criteria essential for determining material compatibility without directly referencing the originating regulatory body or the specific date of adoption.
