Compressed Natural Gas Vehicle (NGV) Fueling Connection Devices
1.1 This standard 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 1.5); 2. Nozzle (see 1.3); and/or 3. Three-way valve (external to nozzle and mounted in the fuel dispenser system) (see 1.6). 1.2 This standard applies to devices which have a service pressure of either 16,500 kPa (2400 psi), 20,700 kPa (3000 psi), or 24,800 kPa (3600 psi), herinafter referred to in this standard as the following (see 1.9.1-c): "P24" - 16,500 kPa (2400 psi) "P30" - 20,700 kPa (3000 psi) "P36" - 24,800 kPa (3600 psi) 1.3 This standard applies to devices which will not allow gas to flow until a positive connection has been achieved and will not allow disconnection until captured gas has been safely vented. 1.4 This standard applies to devices with standardized mating components (see 1.3.9, 1.5.6 and 1.7.) 1.5 This standard 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. 1.6 All dimensions used in this standard are in metric units [International System of Units (SI)], unless otherwise specified. If a value for measurement, as given in this standard, is followed by an equivalent value in other units, the first stated value is to be regarded as the specification. 1.7 Exhibit E contains a list of standards specifically referenced in this standard, and sources from which these referenced standards may be obtained. 1.8 For the purposes of this standard, compressed natural gas shall comply with the specifications under 2-2, Gas Quality, in the standard for Compressed Natural Gas (CNG) Vehicular Fuel Systems, ANSI/NFPA 52. 1.9 All references to "psi or kPa" throughout this standard are to be considered gage pressures unless otherwise specified.
