Gaseous hydrogen land vehicle refuelling connection devices (ISO 17268:2012)
ISO 17268:2012 defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors consisting of, as applicable, a receptacle and a protective cap (mounted on vehicle), and a nozzle.
It applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa, 35 MPa and 70 MPa, referred to as
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), and
H70 - 70 MPa at 15 °C.
Nozzles and receptacles that meet the requirements of ISO 17268:2012 will only allow GHLVs to be filled 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 with natural gas are excluded from the scope of ISO 17268:2012.

Dispositifs de raccordement pour le ravitaillement des véhicules terrestres à hydrogène gazeux (ISO 17268:2012)
L'ISO 17268:2012 définit les caractéristiques de conception, de sécurité et d'exploitation des raccords destinés au ravitaillement des véhicules terrestres à hydrogène gazeux (GHLV).
Les raccords de ravitaillement des GHLV sont constitués des éléments suivants, selon le cas:
- un réceptacle et un bouchon de protection (montés sur le véhicule);
- un embout.
L'ISO 17268:2012 s'applique aux raccords de ravitaillement ayant une pression de service de 11 MPa, 25 MPa, 35 MPa et 70 MPa, désignés dans l'ISO 17268:2012 comme suit:
- H11 - 11 MPa à 15 °C;
- H25 - 25 MPa à 15 °C;
- H35 - 35 MPa à 15 °C;
- H35HF - 35 MPa à 15 °C (haut débit pour applications sur véhicules commerciaux);
- H70 - 70 MPa à 15 °C.
Les embouts et les réceptacles qui satisfont aux exigences de l'ISO 17268:2012 permettront le ravitaillement des GHLV uniquement via des stations de recharge distribuant de l'hydrogène à une pression de service nominale inférieure ou égale à la pression de service du circuit de carburant du véhicule. Ils ne permettront pas le ravitaillement des GHLV via des stations de recharge distribuant des mélanges d'hydrogène et de gaz naturel.
Les raccords de ravitaillement servant à distribuer des mélanges d'hydrogène et de gaz naturel sont exclus du domaine d'application de l'ISO 17268:2012.
NOTE L'ISO 17268:2012 peut être utilisée à des fins de certification.
Plinasti vodik - Priključne naprave za polnjenje goriva v kopenska vozila (ISO 17268:2012)
Ta mednarodni standard opredeljuje načrtovanje, varnost in obratovalne lastnosti priključkov za polnjenje plinastega vodika v kopenska vozila (GHLV). Priključki za polnjenje plinastega vodika v kopenska vozila so sestavljeni iz naslednjih sestavnih delov, kot je ustrezno: – vtičnica in zaščitni pokrov (nameščena na vozilo); – šoba. Ta mednarodni standard se uporablja za priključke za polnjenje z delovnimi tlaki 11 MPa, 25 MPa, 35 MPa in 70 MPa (v nadaljevanju tega mednarodnega standarda: – H11 – 11 MPa pri 15° C; – H25 – 25 MPa pri 15° C; – H35 – 35 MPa pri 15° C; – H35HF – 35 MPa pri 15° C (visok pretok za uporabo pri komercialnih vozilih); – H70 – 70 MPa pri 15° C. Šobe in vtičnice, ki izpolnjujejo zahteve tega mednarodnega standarda, omogočajo polnjenje plinastega vodika v kopenska vozila samo na polnilnih postajah, ki polnijo vodik z nazivnimi delovnimi tlaki, enakimi ali nižjimi od delovnega tlaka sistema za gorivo vozila. S temi šobami in vtičnicami ni mogoče polniti plinastega vodika v kopenska vozila na polnilnih postajah, ki polnijo mešanice vodika in zemeljskega plina. Priključki za polnjenje, ki polnijo mešanice vodika in zemeljskega plina, ne spadajo na področje uporabe tega mednarodnega standarda. OPOMBA: Ta mednarodni standard se lahko uporablja za namene certificiranja.

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 17268 was prepared by Technical Committee ISO/TC 197, Hydrogen technologies.
This second edition cancels and replaces the first edition (ISO 17268:2006), which has been technically revised.

INTERNATIONAL STANDARD ISO 17268:2012(E)
Gaseous hydrogen land vehicle refuelling connection devices
1 Scope
This International Standard defines the design, safety and operation characteristics of gaseous hydrogen land
vehicle (GHLV) refuelling connectors.
GHLV 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 International 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
filled 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 with natural gas are excluded from the scope of this
International Standard.
NOTE This International Standard can be used for certification purposes.
