CSA NGV1-2006

1.1 Scope 1.1.1 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, Receptacles); 2. Nozzle (see 1.3, Nozzles); and/or 3. Three-way valve (external to nozzle and mounted in the fuel dispenser system) (see 1.6, Three-Way Valve). 1.1.2 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), hereinafter 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) 1.1.3 This standard applies to devices with standardized mating components (see 1.3.9, 1.5.6 and 1.7, Interchangeability.) 1.1.4 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. 1.1.5 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.
