Scope

This Standard specifies the minimum allowable values of energy efficiency,
evaluating values of energy conservation, energy efficiency grades, test
methods, and inspection rules for hydrogen producing systems by water
electrolysis (hereinafter referred to as hydrogen producing systems).
This Standard applies to fixed or mobile hydrogen producing systems. The
structure of water electrolyser is bipolar, press-filtration, pressure type; the
output is ≥5 m3/h.
This Standard does not apply to atmospheric-pressure hydrogen producing
equipment by water electrolysis, small-scale hydrogen producing equipment
with an output < 5 m3/h, solid polymer electrolyte electrolyser (SPE), and
hydrogen-oxygen generator.
