22、 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-
23、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
24、.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 v
25、ote.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 17268 was prepared by Technical Committee ISO/TC 197, Hydrogen technologies.This second editio

GH
27、LV refuelling connectors consist of the following components, as applicable: receptacle and protective cap (mounted on vehicle); nozzle.This International Standard applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa, 35 MPa and 70 MPa, hereinafter referred to in this Inte
28、rnational Standard as the following: H11 11 MPa at 15 C; H25 25 MPa at 15 C; H35 35 MPa at 15 C; H35HF 35 MPa at 15 C (high flow for commercial vehicle applications); H70 70 MPa at 15 C.Nozzles and receptacles that meet the requirements of this International Standard will only allow GHLVs to be fill
29、ed by fuelling stations dispensing hydrogen with nominal working pressures equal to or lower than the vehicle fuel system working pressure. They will not allow GHLV to be filled by fuelling stations dispensing blends of hydrogen with natural gas.Refuelling connectors dispensing blends of hydrogen wi
30、th natural gas are excluded from the scope of this International Standard.NOTE This International Standard can be used for certification purposes.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
