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;
d) automatic valves;
e) gas injectors;
f) pressure indicators;
g) pressure regulator;
h) pressure relief valves;
i) pressure relief devices;
j) excess flow valves;
k) gas-tight housing and leakage capture lines and passages;
l) rigid fuel lines;
m) flexible fuel lines;
n) filter housing;
o) fittings; and
p) discharge line closures.
Note: It is recognized that other components not specifically covered herein can be examined to meet the criteria of HGV 3.1 and tested according to the appropriate functional needs.
1.2 This Standard applies to devices that have a service pressure of either 25MPa, 35MPa, 50MPa, or 70MPa hereinafter referred to in this Standard as the following:
a) “H25” – 25 MPa;
b) “H35” – 35 MPa;
c) “H50” – 50 MPa;
d) “H70” – 70 MPa.
This Standard also applies to components downstream of the first stage of pressure reduction with a maximum operating pressure designated by the manufacturer in kPa (psi).
1.3 This Standard addresses the pressure containment, performance, and safety characteristics of components listed Clause 1.1.
1.4 This Standard does not apply to the following:
a) hydrogen gas fuel system components incorporated during the manufacture of motor vehicles originally manufactured in compliance with the Federal Motor Vehicle Safety Standards (FMVSS) for Compressed Hydrogen Gas Fueled Vehicles and the Canadian Motor Vehicle Safety Standard (CMVSS);
b) fuel containers;
c) stationary gas engines;
d) container mounting hardware;
e) electronic fuel management;
f) refueling receptacles; or
g) three-way valves.
