8、ography .45 ISO 16380:2014(E) 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 interes
9、ted 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 C
10、ommission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documen
11、ts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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
12、 for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for t
13、he convenience of users and does not constitute an endorsement.

14、Foreword - Supplementary information The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 25, Vehicles using gaseous fuel. iv ISO 2014 All rights reserved ISO 16380:2014(E) Introduction A nozzle certified to this International Standard will be functionally compati
15、ble from a safety and performance perspective with all listed receptacles of compatible profile and system pressure. Similarly, a receptacle certified to this International Standard will be functionally compatible from a safety and performance perspective with all listed nozzles of compatible profil
16、e and system pressure. As there can eventually be many different kinds of nozzles and receptacles available from a variety of manufacturers which, for safety reasons, shall all be compatible with each other, this International Standard specifies a series of receptacle profiles. These standard profil
17、es incorporate the design specifications (mating materials, geometry, and tolerances) which can be considered in the certification of a submitted nozzle or receptacle. The construction and performance of nozzles and receptacles are based on the observation that four main parameters affect user safet
18、y and system compatibility. ISO 2014 All rights reserved v Road vehicles Blended fuels refuelling connector 1 Scope This International Standard applies to compressed blended fuels vehicle nozzles and receptacles hereinafter referred to as devices, constructed entirely of new, unused parts and materi
19、als. Compressed blended fuels fuelling connection nozzles consist of the following components, as applicable: a) Receptacle and protective cap (mounted on vehicle) (see Clause 7); b) Nozzle (mounted on dispenser side) (see Clause 5). This International Standard applies to devices which have a servic
20、e pressure of 20 MPa, 25 MPa, and 35 MPa hereinafter referred to in this International Standard as see 9.1 c): size 1: M200, M250, and M350; size 2: N200 and N250. This International Standard refers to service pressures of 20 MPa, 25 MPa, and 35 MPa for size 1 and 20 MPa and 25 MPa for size 2. This
21、International Standard applies to devices with standardised mating components (see 5.8 and 7.7). This International Standard applies to connectors which a) prevent blended fuels vehicles from being fuelled by dispenser stations with working pressures higher than the vehicle fuel system working press
22、ure, b) allow blended fuels vehicles to be fuelled by dispenser stations with working pressures equal to or lower than the vehicle fuel system working pressure, c) allow blended fuels vehicles to be fuelled by dispenser stations for compressed natural gas, d) allow blended fuels vehicles to be fuell
23、ed by compressed natural gas dispenser stations with working pressures equal to or lower than the vehicle fuel system working pressure, e) prevent blended fuels vehicles size 1 being refuelled on blended fuels dispenser stations equipped with a size 2 nozzle and vice versa, f) prevent natural gas ve
24、hicles from being fuelled by blended fuels station, and dispensers, and g) prevent pure hydrogen vehicles from being fuelled by blended fuels station dispensers. This International Standard is applicable to mixtures of hydrogen from 2 % to 30 % in volume and compressed natural gas containing: a) nat
25、ural gas in accordance with ISO 15403-1 and ISO 15403-2; b) pure hydrogen in accordance with ISO 14687-1 or ISO/TS 14687-2. All references to pressures (MPa) throughout this International Standard are to be considered gauge pressures unless otherwise specified. INTERNATIONAL ST ANDARD ISO 16380:2014

38、alve 4 General construction requirements a) There are two different sizes of refuelling systems, size 1 and size 2. Size 1 should suit the need of smaller vehicles with a limited tanks size. Therefore, the flow diameter is limited by the inner front diameter of the receptacle in this case 7,8 mm 0,2
39、 mm. Size 2 should suit the need of commercial vehicles like busses and trucks. Therefore, the flow diameter is limited by the inner front diameter of the receptacle in this case 12 mm 0 2mm. Also, the profile of the two different sizes is so different that no cross connection between the sizes is p
40、ossible. b) Working pressure (= 1,25 times service pressure). All nozzles and receptacles are designed to have a working pressure of: ISO 2014 All rights reserved 3 ISO 16380:2014(E) Code Service pressure Working pressure Size 1 M200 20 MPa 25 MPa M250 25 MPa 31,25 MPa M350 35 MPa 43,75 MPa Size 2 N
41、200 20 MPa 25 MPa N250 25 MPa 31,25 MPa c) Design life. Frequency of use is the second parameter to be considered. Since frequency of use will differ with the nozzle/receptacle application (i.e. public sector, fleet employee, and residential), all receptacles will be tested at 10 000 connect/disconn
42、ect cycles for compliance with this International Standard. In addition, all nozzles shall be tested according to the following frequency use classifications, as applicable. Class A Nozzle - This class specifies high frequency use, with a cycle life of 100 000. This equates to approximately 100 fill
43、s per day for three years. Class B Nozzle - This class specifies medium frequency use, with a cycle life of 20 000 cycles. This equates to approximately 10 fills per day for five years. d) Training. Operator. Training required is in accordance with national requirements. 4.1 Compressed blended fuels
44、 nozzles and receptacles shall be well fitted and manufactured in accordance with good engineering practice. All construction requirements can be met by either the construction specified in this International Standard or another construction that gives at least equivalent performance. 4.2 Compressed
45、 blended fuels nozzles and receptacles shall be: designed to minimize the possibility of incorrect assembly; designed to be secure against displacement, distortion, warping, or other damage; constructed to maintain operational integrity under normal and reasonable conditions of handling and usage. 4
46、.3 Nozzles and receptacles shall be manufactured of materials suitable and compatible for use with compressed blended fuels at the pressure and the temperature ranges to which it will be subjected. 4.3.1 The temperature ranges shall be: Table 1 Temperature ranges Location on board Location a Locatio

49、 fuel that can be expected in this system. 4.5 Separate external three-way valves shall be constructed and marked so as to indicate clearly the open, shut, and vent positions. 4.6 Compressed blended fuels nozzles and receptacles shall be operated either to connect or disconnect without the use of tools. 4.7 Jointing components shall provide gas tight sealing performance.
