Compressed Natural Gas Vehicle (NGV) High flow Fueling Connection Devices - Supplement to NGV 1-2006
|Publication Date:||1 January 2015|
This Interim Requirement applies to newly produced compressed Natural Gas Vehicle (NGV) fueling connection devices, hereinafter referred to as devices, constructed entirely of new, unused parts and materials. NGV fueling connection devices shall consist of the following components, as applicable:
1. Receptacle and protective cap (mounted on vehicle) (see Clause 1.5, Receptacles);
2. Nozzle (see Clause 1.3, Nozzles); and/or
3. Three-way valve (external to nozzle and mounted in the fuel dispenser system) (see Clause 1.6, Three-Way Valve).
This Interim Requirement supplements CSA Group's American National Standard/CSA Standard for Compressed Natural Gas Vehicle (NGV) Fueling Connection Devices NGV 1-2006.
This Interim Requirement applies to devices which have a service pressure of 24 800 kPa (3600 psi), hereinafter referred to in this Interim Requirement as the following (see Clause 1.9.1-c):
"P30HD" - 20 700 kPa (3000 psi)
"P36HD" - 24 800kPa (3600 psi)
This Interim Requirement applies to devices with standardized mating components (see Clauses 1.5.5, and 1.7, Interchangeability.)
This Interim Requirement applies to devices which (1) prevent natural gas vehicles from being fueled by dispenser stations with service pressures higher than the vehicle, and (2) allow natural gas vehicles to be fueled by dispenser stations with service pressures equal to or lower than the vehicle fuel system service pressure.
All dimensions used in this Interim Requirement are in metric units [International System of Units (SI)], unless otherwise specified. If a value for measurement, as given in this Interim Requirement, is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
Exhibit A contains a list of standards specifically referenced in this Interim Requirement, and sources from which these referenced standards may be obtained.
For the purposes of this Interim Requirement, compressed natural gas shall comply with the specifications under "Gas Quality", in the Standard for Compressed Natural Gas (CNG) Vehicular Fuel Systems, ANSI/NFPA 52.
All references to "psi or kPa" throughout this Interim Requirement are to be considered gage pressures unless otherwise specified.
