PD ISO/TS 21104 is the international standard on road vehicles discussing liquefied natural gas (LNG) low-pressure refuelling and venting connector.
PD ISO/TS 21104 specifies liquefied natural gas (LNG) refuelling nozzles and receptacles constructed entirely of new and unused parts and materials for road vehicles powered by LNG.
An LNG refuelling connector consists of, as applicable, the receptacle and the nozzle.
NOTE: PD ISO/TS 21104 is applicable only to such devices designed for a working pressure of 1,8 MPa to those using LNG as a vehicle fuel and having standardized mating components.
PD ISO/TS 21104 on LNG is useful for:
LNG refuelling nozzle is a device that permits quick connection and disconnection of fuel supply hose to the LNG receptacle in a safe manner as well as LNG refuelling receptacle is a device connected to a vehicle or storage system which receives the LNG refuelling nozzle and permits the safe transfer of fuel.
PD ISO/TS 21104 provides the general construction requirements of LNG nozzles and receptacles with a vapour spillage space and positive locking device.
Pressure rating and working temperature range of material can be determined by PD ISO/TS 21104.
Venting depressurization and identification of all nozzle types are specified in PD ISO/TS 21104 indicating the direction of the open and shut off operation of the actuating mechanism.
PD ISO/TS 21104 navigates you through the standard receptacle dimensions and specifies the instructions and provisions for nozzles and receptacles.
Moreover, PD ISO/TS 21104 could help you in manufacturing LNG nozzles and receptacles used in road vehicles to permit the transfer of liquid or gaseous fuels to power the vehicle improving air quality in cities. In this way, LNG nozzles and receptacles make transport and storage much more efficient and cost-effective.
