Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

Individuals, companies, and associations across Canada indicate their support for CSA Group’s standards development by

volunteering their time and skills to Committee work and supporting CSA Group’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA Group’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA Group’s standards development activities.

CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the

CSA Group Mark.

In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service

organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

Gaseous hydrogen — Fuelling stations —

(ISO 19880-3:2018, MOD)

CSA Preface

This is the second edition of CSA/ANSI HGV 4.4, Gaseous hydrogen — Fuelling stations — Valves, which is an adoption, with North American deviations, of ISO (International Organization for Standardization) Standard 19880-3 (first edition, 2018-06), Gaseous hydrogen — Fuelling stations — Part 3: Valves. It supersedes the previous edition, published in 2013 as ANSI/CSA HGV 4.4, Breakaway devices for compressed hydrogen dispensing hoses and systems. It also replaces ANSI/CSA HGV 4.6-2013, Manually operated valves for use in gaseous hydrogen vehicle fueling stations, and ANSI/CSA HGV 4.7-2013, Automatic valves for use in gaseous hydrogen vehicle fueling stations. At the time of publication,

ISO 19880-3:2018 is available from ISO in English only. CSA Group will publish the French version when it becomes available from ISO.

For brevity, this Standard will be referred to as “CSA/ANSI HGV 4.4” throughout.

This edition of CSA/ANSI HGV 4.4 harmonizes with other North American requirements, including those referenced in CAN/BNQ-1784-000, Canadian Hydrogen Installation Code.

The North American deviations are intended to

1. correct inaccuracies; and

2. replace references to ISO Standards with references to North American Standards, where applicable.

This Standard provides safety performance requirements and test methods for valves to be used in gaseous hydrogen environments. This Standard is based on engineering principles, research, and the combined expertise of manufacturers, users, and others having specialized experience.

Nothing in this Standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of products that may exceed that specified in the provisions herein. In its preparation, full recognition has been given to possibilities of improvement through ingenuity of design. This Standard is subject to revision as further experience and investigation might show that it is necessary and desirable.

Users of this Standard are advised that the devices/products/activities within its scope could be subject to regulation at the federal, state, or local levels. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this Standard, the federal, state, or local regulations should be followed.

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was reviewed for North American adoption by the CSA Subcommittee on Breakaway Devices for Compressed Hydrogen Dispensing Hoses and Systems, under the jurisdiction of the CSA Technical Committee on Hydrogen Transportation and the CSA Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee and the Interprovincial/ Territorial Gas Advisory Council.

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.
