Preface:

This publication represents a standard for safe operation, substantial and durable construction and performance testing of the mechanical and electrical features of newly manufactured hydrogen gas dispensing systems for vehicles, intended primarily to dispense fuel directly into the vehicle fuel storage container.

Scope:

1.1.1
This Standard applies to:
a. The mechanical and electrical features of newly manufactured systems that dispense compressed hydrogen gas for vehicles (HGV) where such systems are intended primarily to dispense the fuel directly into the fuel storage container of the vehicle.
b. HGV dispensers that integrate in a single unit multiple dispensing functions (e.g., fuel metering, registering, control and management devices, vehicle fuel cylinder overfill and over pressure protection with listed hoses with nozzles).
c. The following service pressures are applicable, 25MPa, 35MPa, 50MPa, 70MPa:

Each dispenser may have the capability of independently fueling more than one vehicle simultaneously.

1.1.2
HGV dispensers covered by this standard are intended for use with gas composition specified by the Hydrogen Fuel Quality for Fuel Cell Vehicles, SAE J2719.

1.1.3
This Standard applies to dispensers that include fuel metering, registering, control and management devices, vehicle fuel cylinder overfill and vehicle fuel cylinder over pressure protection.

1.1.4
This Standard does not apply to dispensers that are part of a modular fueling station with remote fuel metering, registering, control and management devices, vehicle fuel cylinder overfill and over pressure protection included in an integrated fueling station control system. For these applications refer to CSA America HGV 4.9, Hydrogen Fueling Station Safety Guideline.

1.1.5
Installation of a dispensing system is intended to be in accordance with the, Hydrogen Motor Fuel Dispensing and Generating Facilities Standards, ICC 2006 International Fire Code, Section 2209, or Hydrogen Technologies Code, ANSI/NFPA 2, as applicable, and the requirements of the authority having jurisdiction.

1.1.6
All dimensions used in this standard are in metric units [International System of Units (SI)], unless otherwise specified. If a value for a measurement, as given in this standard, is followed by an equivalent value in other units, the first stated is to be regarded as the specification.

1.1.7
All references to pressure throughout this document are to be considered gauge pressures unless otherwise specified.

1.1.8
Exhibit B contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
