Design

1. PURPOSE
This protocol is intended to establish design criteria and test procedures applicable to mechanical energy storage systems for the purpose of verifying and documenting the safety of these systems.
2. SCOPE

IEC 62282-2:2012 provides the minimum requirements for safety and performance of fuel cell modules; it applies to fuel cell modules with or without an enclosure which can be operated at significant pressurization levels or close to ambient pressure. Deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. This edition includes the following significant technical changes with respect to the previous edition:
- inclusion of definitions for hazards and hazardous locations based on the IEC 60079 series;

ISO 22734-1:2008 defines the construction, safety and performance requirements of packaged or factory matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen and oxygen gas.
It is applicable to hydrogen generators that use the following types of ion transport medium:
Group of aqueous bases;
Solid polymeric materials with acidic function group additions such as acid proton exchange membrane (PEM).

This International Standard specifies the essential requirements for fuel cell vehicles (FCV) with respect to the protection of persons and the environment inside and outside the vehicle against hydrogen-related hazards.
It applies only to such FCV where compressed hydrogen is used as fuel for the fuel cell system.
This International Standard does not apply to manufacturing, maintenance, and repair.
The requirements of this International Standard address both normal operating (fault-free) and single-fault conditions of the vehicles.

Preface
This is the eighteenth edition of CSA B51, Boiler, pressure vessel, and pressure piping code. It supersedes the previous editions published in 2009, 2003, 1997, 1995, 1991, 1986, 1981, 1975, 1972, 1969, 1965, 1960, 1957, 1955, 1951, 1945, and 1939.

ASME has been defining piping safety since 1922.
ASME B31.3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals. It covers materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping.

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.

Preface
This is the first edition of ANSI HGV 3.1, Fuel system components for compressed hydrogen gas powered vehicles. This precedes CSA HGV 3.1-2013.

Scope
1.1
This Standard establishes requirements for newly produced compressed hydrogen gas fuel system components, intended for use on hydrogen gas powered vehicles as listed below:

a) check valves;

b) manual valves;

c) manual container valves;

1 Scope
1.1 These requirements cover battery chargers rated 600 volts or less. They are intended to be used in accordance with the National Electrical Code, NFPA 70, to charge industrial storage batteries which are used to provide power for material handling trucks, tractors, personnel carriers, and similar motive equipment. These chargers may be either cord and plug connected or permanently connected.

Guidance and implementation procedures for the IEEE 1680 family of standards is provided, and the methods by which manufacturers may declare electronic products as conforming with the standards in the IEEE 1680 family of standards and by which such conformance may be verified are defined. The standards within the family will provide clear and consistent performance criteria for the design of electronic products, thereby providing an opportunity to secure market recognition for efforts to reduce the environmental impact of electronic products.
