This international standard applies to packaged, self-contained or factory matched hydrogen generation systems with a capacity less than 400 m3/hr at 20 °C and 101,325 kPa, herein referred as hy drogen generators, that convert an input fuel to a hydrogen rich stream of composition and conditions suitable for the type of device using the hydrogen (e.g. a fuel cell power system or a hydrogen compression, storage and delivery system).
It applies to hydrogen generators using one or a combination of the following input fuels:
a) natural gas and other methane rich gases derived from renewable (biomass) or fossil fuel sources, e.g. landfill gas, digester gas, coal mine gas;
b) fuels derived from oil refining, e.g. diesel, gasoline, kerosene, liquefied petroleum gases such as propane and butane;
c) alcohols, esters, ethers, aldehydes, ketones, Fischer-Tropsch liquids and other suitable hydrogen-rich organic compounds derived from renewable (biomass) or fossil fuel sources, e.g. methanol, ethanol, dimethyl ether, biodiesel;
d) gaseous mixtures containing hydrogen gas, e.g. synthesis gas, town gas.
This standard is applicable to stationary hydrogen generators intended for indoor and outdoor commercial, industrial, light industrial and residential use.
This standard aims to cover all significant hazards, hazardous situations and events relevant to hydrogen generators, with the exception of those associated with environmental compatibility (installation conditions), when they are used as intended and under the conditions foreseen by the manufacturer.
NOTE – A list of significant hazards and hazardous situations dealt with in this standard is found in Annex A.
This international standard is a product safety standard suitable for conformity assessment as stated in
IEC Guide 104, ISO/IEC Guide 51 and ISO/IEC Guide 7.
