标准范围

ISO 17268:2012定义了气态氢陆地车辆（GHLV）加注连接器的设计、安全和操作特性，该连接器由插座和保护帽（安装在车辆上）以及喷嘴组成（如适用）。它适用于工作压力为11 MPa、25 MPa、35 MPa和70 MPa的加油连接器，简称在15℃下H11-11MPa，H25-25 MPa，在15℃，在15℃下H35-35MPa，H35HF–在15℃下为35 MPa(用于商用车辆应用的高流量)，以及H70-70 MPa，在15℃下。符合ISO 17268:2012要求的喷嘴和容器仅允许GHLV由加气站加注标称工作压力等于或低于车辆燃料系统工作压力的氢气。他们不允许加气站分配氢气和天然气的混合物来填充GHLV。分配氢气与天然气混合物的加油连接器不在ISO 17268:2012的范围内。

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.
