【1】GB/T 30074-2013 用电化学技术测量金属中氢渗透（吸收和迁移)的方法 Method of measurement of hydrogen permeation and determination of hydrogen uptake and transport in metals by an electrochemical technique(ISO 17801:2004, MOD)

本标准规定了根据氢在金属中稳态扩散通量的测定结果评价氢在金属中吸收量以及测定氢原子在金属中的有限扩散系数和鉴别对氢可逆和不可逆捕集的方法。适用于所有可能测量氢渗透的金属，用于比较技术暴露在不同环境中氢吸收能力的大小。

【2】ASTM G148-97（2018） Standard Practice for Evaluation of Hydrogen Uptake, Permeation, and Transport in Metals by an Electrochemical Technique

This practice gives a procedure for the evaluation of hydrogen uptake, permeation, and transport in metals using an electrochemical technique which was developed by Devanathan and Stachurski. While this practice is primarily intended for laborotary use, such measurement have been conducted in filed or plant applications. Therefore, with proper adaptations, this practice can also be applied to such situations.

【3】ISO 17081:2014 Method of measurement of hydrogen permeation and determination of hydrogen uptake ans transport in metals by an electrochemical technique

This standard specifies a laboratory method for the measurement of hydrogen permeation and for the dermination of hydrogen atom uptake and transport in metals, using an electrochemical technique. It describe a method for evaluation hydrogen uptake in metals, based on measurement of steady-state hydrogen flux. It also describes a method for determining effective diffusicity of hydrogen atoms in a metal and for distingushing revesible and irreversible trapping.
