This document applies only to Dimethyl Ether refuelling connectors with pressure equalizing port hereinafter referred to as devices, constructed entirely of new, unused parts and materials. Dimethyl Ether refuelling connectors with pressure equalizing port consist of the following components, as applicable:
a) Nozzle with pressure equalizing port Refuelling nozzle and pressure equalizing port are integrated so that connecting of refuelling path
and pressure equalizing path are performed with a single action (mounted on dispenser side) (see Clause 5).
b) Receptacle with pressure equalizing port (mounted on vehicle) (see Clause 7) This document applies to devices which are for Dimethyl Ether as fuel, hereinafter referred to in this document as M15(see 9.1c):
This document applies to devices with standardised mating components.
This document applies to connectors which prevent Dimethyl Ether vehicles from being fuelled by fuel station dispensers for other gaseous fuels
This document is applicable to: Dimethyl Ether in accordance with ISO 16861.
All references to pressures (kPa) throughout this document are considered gauge pressures unless otherwise specified.
