Specifications

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).

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.

IEC 61131-6:2012 specifies requirements for programmable controllers (PLCs) and their associated peripherals, as defined in Part 1, which are intended to be used as the logic subsystem of an electrical/electronic/programmable electronic (E/E/PE) safety-related system. A programmable controller and its associated peripherals complying with the requirements of this part is considered suitable for use in an E/E/PE safety-related system and is identified as a functional safety programmable logic controller (FS-PLC). An FS-PLC is generally a hardware (HW) / software (SW) subsystem.

IEC 61850-5:2013 applies to power utility automation systems with the core part of substation automation systems (SAS); it standardizes the communication between intelligent electronic devices (IEDs) and defines the related system requirements to be supported. The major technical changes with regard to the previous edition are as follows:
- extension from substation automation systems to utility automation systems;
- inclusion of interfaces for communication between substations;
- requirements from communication beyond the boundary of the substation.

IEC/IEEE 61850-9-3:2016(E) specifies a precision time protocol (PTP) profile of IEC 61588:2009 / IEEE Std 1588-2008 applicable to power utility automation, which allows compliance with the highest synchronization classes of IEC 61850-5 and IEC 61869-9.

IEC/TR 61850-90-1:2010(E) provides a comprehensive overview on the different aspects that need to be considered while using IEC 61850 for information exchange between substations. In particular, this technical report defines use cases that:
- require an information exchange between substations;
- describes the communication requirements;
- gives guidelines for the communication services and communication architecture to be used;
- defines data as a prerequisite for interoperable applications;

IEC TR 61850-90-2:2016(E) provides a comprehensive overview of the different aspects that need to be considered while using IEC 61850 for information exchange between substations and control or maintenance centres or other system level applications. In particular, this technical report:
- defines use cases and communication requirements that require an information exchange between substations and control or maintenance centres;
- describes the usage of the configuration language of IEC 61850-6;

IEC 61131-5:2000 specifies communication aspects of a programmable controller. It specifies from the viewpoint of a PC how any device can communicate with a PC as a server and how a PC can communicate with any device. In particular, it specifies the behavior of the PC as it provides services on behalf of other devices and the services the PC application program can request from other devices. This bilingual version (2012-08) corresponds to the monolingual English version, published in 2000-11.
This publication is to be read in conjunction with the IEC 61131 series.
