Road vehicles - Compressed natural gas (CNG) refuelling connector - Part 2: 20 MPa (200 bar) connector, size 2 (ISO 14469-2:2007)

ISO 14469-2:2007 applies to compressed natural gas (CNG) vehicle nozzles and receptacles, constructed entirely of new, unused parts and materials for which there is a demand, in particular for large CNG urban buses of refuelling times equivalent to those of urban buses driven by conventional diesel engines. The proposed connector, size 2, offers a larger cross section than the connector in accordance with ISO 14469-1 and, therefore, permits refuelling of the vehicles within significantly shorter time periods. Studies have shown that the proposed connector, size 2, offers more than twice the mass flow of the connectors specified in ISO 14469-1. CNG fuelling connection nozzles consist of the following components, as applicable:
receptacle and protective cap (mounted on vehicle);
nozzle.
ISO 14469-2:2007 applies only to devices which have a service pressure of 20 MPa.
ISO 14469-2:2007 applies to devices with standardized mating components.
ISO 14469-2:2007 applies to connectors which
prevent natural gas vehicles from being fuelled by dispenser stations with service pressures higher than the vehicle, and
allow natural gas vehicles to be fuelled by dispenser stations with service pressures equal to or lower than the vehicle fuel system service pressure.
ISO 14469-2:2007 is applicable to compressed natural gas in accordance with ISO 15403.

ISO 14469-2:2007(E) iv © ISO 2007 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14469-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 25, Vehicles using gaseous fuels. ISO 14469 consists of the following parts, under the general title Road vehicles — Compressed natural gas (CNG) refuelling connector: ⎯ Part 1: 20 MPa (200 bar) connector ⎯ Part 2: 20 MPa (200 bar) connector, size 2 ⎯ Part 3: 25 MPa (250 bar) connector
ISO 14469-2:2007(E) © ISO 2007 – All rights reserved vIntroduction This part of ISO 14469 was developed for use in the examination, testing and certification of newly produced compressed natural gas (CNG) vehicle fuelling nozzles and receptacles. As such, it applies only to the nozzles and receptacles used in CNG fuelling systems, and not to the system itself. A nozzle certified to this part of ISO 14469 will be functionally compatible from a safety and performance perspective with all listed receptacles of compatible profile and system pressure. Similarly, a certified receptacle will be functionally compatible from a safety and performance perspective with all listed nozzles of compatible profile and system pressure. As there may eventually be many different kinds of nozzles and receptacles available from a variety of manufacturers which, for safety reasons, all need to be compatible with one another, this part of ISO 14469 specifies a series of receptacle profiles. These standard profiles incorporate the design specifications (mating materials, geometry and tolerances) that may be considered in the certification of a submitted nozzle or receptacle. This part of ISO 14469 refers only to one working pressure and one application. Other working pressures and applications are under consideration for the future. The construction and performance of nozzles and receptacles are based on the observation that three main parameters listed below affect user safety and system compatibility. a) Working pressure: all nozzles and receptacles are designed to have a working pressure of 25 MPa1). b) Design life: since frequency of use will differ with the nozzle/receptacle application (i.e. public sector, fleet employment and residential), all receptacles will be tested at 10 000 connect/disconnect cycles for compliance with this part of ISO 14469. In addition, all nozzles will be tested according to the following frequency use classifications, as applicable: 1) class A nozzle, specifying high frequency use, with a cycle life of 100 000 and equating to approximately 100 fills per day for three years; 2) class B nozzle, specifying medium frequency use, with a cycle life of 20 000 and equating to approximately 10 fills per day for five years. c) Training: operator training required is in accordance with national requirements.

This part of ISO 14469 applies to devices with standardized mating components (see 5.8 and 7.7).

This part of ISO 14469 is applicable to compressed natural gas in accordance with ISO 15403. All references to pressures throughout this part of ISO 14469 are considered to be gauge pressures unless otherwise specified.
