Description

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.
