Thermally activated pressure relief devices for compressed hydrogen vehicle fuel containers

Preface   This publication represents a standard for safe operation, substantial and durable construction and performance testing of thermally activated pressure relief devices for compressed hydrogen vehicle fuel containers, for the on-board storage of compressed hydrogen for vehicle operation within limitations given below and in the scope of this standard.   This Standard is based on proven engineering principles, research and the combined expertise of gas utilities, 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 which 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 may show it is necessary and desirable.   This Standard does not apply to fuel system components that will be incorporated during original manufacture of motor vehicles which comply with Federal Motor Vehicle Safety Standards (FMVSS) or Canadian Motor Vehicle Safety Standards (CMVSS) for Natural Gas Powered Vehicles.   Scope   1.1 This Standard establishes minimum requirements for pressure relief devices intended for use on fuel containers that comply with CSA B51, Part 2 Boiler, Pressure Vessel and Pressure Piping Code or SAE J2579, Technical Information Report for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles.   Pressure relief devices designed to comply with this standard are intended to be used with hydrogen fuel complying with SAE J2719 Hydrogen Fuel Quality for Fuel Cell Vehicles, or ISO 14687 Hydrogen Fuel-Product Specification.   Pressure relief devices may be of any design or manufacturing method that meets the requirements of this standard.   The construction of pressure relief devices, whether specifically covered in this standard or not, shall be in accordance with reasonable concepts of safety, performance and durability.   This Standard does not apply to reseating resealing or pressure activated devices.
