Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

ISO 19880-3:2018(E)
Introduction

Over the course of several years, international efforts have been initiated for the development of

regulations, codes and standards that are required for the introduction of hydrogen energy systems.

Hydrogen has unique properties and therefore presents unique safety concerns.

One of the many hydrogen energy applications is the automobile sector for which commercialization

begun recently. For the success of this application, however, hydrogen infrastructure for fuelling

vehicles is as essential as the hydrogen vehicles themselves. Thus, the development of safety standards

for fuelling stations and components is of paramount importance.

This document provides safety performance requirements and test methods for valves to be used in

gaseous hydrogen environment. Valves are critical to the safety of hydrogen fuelling stations, because

they control the flow of gaseous hydrogen, shut it down in an emergency and, at the same time, may

become a potential source of hydrogen release or leakage.

This document will facilitate the development of hydrogen infrastructure that is needed to pave

a way for the widespread deployment of hydrogen-fuelled vehicles. Benefits to be gained by the

implementation of this document include: the establishment of a certain level of safety performance

for valves, a safety-critical component; the streamlining of the design and construction processes for

fuelling stations by providing standardized components; and the promotion of public acceptance of

hydrogen stations through the transparency of the international standardization processes.

This document is based on the Canadian Standards Association references CSA HGV3.1-2013, ANSI/
