Hydrogen generators using water electrolysis process - Part 2: Residential applications

This standard defines the construction, safety and performance requirements of packaged hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water.*This standard is applicable to hydrogen generators that use the following types of ion transport medium:*- group of aqueous bases;*- solid polymeric materials with acidic function group additions such as acid proton exchange membrane (PEM).*This standard is applicable to hydrogen generators intended for indoor and outdoor residential use (noncommercial and non-industrial use) in sheltered areas such as car-ports, garages, utility rooms and similar areas of a residence. This standard includes cord-connected equipment for outdoor and garage use only.*Hydrogen generators that can also be used to generate electricity such as reversible fuel cells are excluded from the scope of this standard.*This standard does not include portable hydrogen generators.*Hydrogen generators that also supply oxygen as a product are excluded from the scope of this standard.*This standard is intended to be used for certification purposes.
