UL Subject 2264 B Hydrogen Generators Using Water Reaction

Scope This outline covers packaged, self-contained or factory matched packages of integrated gaseous hydrogen generating systems, herein after referred to as hydrogen generators. This outline covers water reaction-type gaseous hydrogen generators, for example, sodium borohydride and sodium hydride. This outline applies to hydrogen generators intended for indoor and outdoor, commercial, industrial and residential use, but not to hydrogen generators intended for vehicular-based propulsion. These requirements do not cover hydrogen generators that can also be used to generate electricity. This outline does not apply to hydrogen generators rated above 600 V.
