Hydrogen generators using water electrolysis — Industrial, commercial, and residential applications (Adopted ISO 22734:2019, first edition, 2019-09, with Canadian and U.S. deviations)
détails du produit
This is the first edition of CSA/ANSI B22734, Hydrogen generators using water electrolysis — Industrial, commercial, and residential applications, which is an adoption with Canadian and U.S. deviations of the identically titled ISO (International Organization for Standardization) Standard 22734 (first edition, 2019-09).
For brevity, this Standard will be referred to as CSA/ANSI B22734 throughout.
The Canadian and U.S. deviations are intended to
a) correct inaccuracies; and
b) replace references to IEC Standards with references to Canadian and U.S. Standards, where applicable.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was reviewed for Canadian and U.S. adoption by the CSA Subcommittee on Hydrogen Generators — Electrolysis, under the jurisdiction of the CSA Technical Committee on Fuel Cells and the CSA Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.
This document defines the construction, safety, and performance requirements of modular or factory-matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen.
This document is applicable to hydrogen generators that use the following types of ion transport medium:
- group of aqueous bases;
- group of aqueous acids;
- solid polymeric materials with acidic function group additions, such as acid proton exchange membrane (PEM);
- solid polymeric materials with basic function group additions, such as anion exchange membrane (AEM).
This document is applicable to hydrogen generators intended for industrial and commercial uses, and indoor and outdoor residential use in sheltered areas, such as car-ports, garages, utility rooms and similar areas of a residence.
Hydrogen generators that can also be used to generate electricity, such as reversible fuel cells, are excluded from the scope of this document.
Residential hydrogen generators that also supply oxygen as a product are excluded from the scope of this document.
