ISO 17081:2014规定了测量氢气的实验室方法 用于测定氢原子在溶液中的吸收和传输 金属，使用电化学技术。ISO中使用的术语“金属” 17081:2014包括合金。 ISO 17081:2014描述了一种评估金属中氢吸收的方法， 基于稳态氢通量的测量。它还描述了一种方法 用于测定金属中氢原子的有效扩散率，以及 区分可逆和不可逆陷阱。 ISO 17081:2014给出了试样制备、控制和试验的要求 以及环境变量的监测、测试程序和数据分析 后果 ISO 17081:2014原则上可适用于所有含氢金属 渗透是可测量的，该方法可用于对相对渗透率进行排序 不同环境对土壤吸氢的侵蚀性 暴露的金属。

ISO 17081:2014 specifies a laboratory method for the measurement of hydrogen permeation and for the determination of hydrogen atom uptake and transport in metals, using an electrochemical technique. The term "metal" as used in ISO 17081:2014 includes alloys. ISO 17081:2014 describes a method for evaluating hydrogen uptake in metals, based on measurement of steady-state hydrogen flux. It also describes a method for determining effective diffusivity of hydrogen atoms in a metal and for distinguishing reversible and irreversible trapping. ISO 17081:2014 gives requirements for the preparation of specimens, control and monitoring of the environmental variables, test procedures and analysis of results. ISO 17081:2014 may be applied, in principle, to all metals for which hydrogen permeation is measurable and the method can be used to rank the relative aggressivity of different environments in terms of the hydrogen uptake of the exposed metal.
