标准范围

ISO 14469-3:20 06适用于完全由新的、未使用的零件和材料制成的压缩天然气（CNG）车辆喷嘴和容器。CNG加注连接喷嘴由以下部件组成（如适用）:插座和保护帽（安装在车辆上）；喷嘴。ISO 14469-3:20 06适用于工作压力为250 bar的设备，并且仅指工作压力为250 bar。ISO 14469的这一部分适用于具有标准化配合组件的设备，并适用于符合以下条件的连接器:防止天然气汽车到服务压力高于车辆的加气站加气；允许天然气汽车由服务压力等于或低于车辆燃油系统服务压力的加气站加气。ISO 14469-3:20 06适用于符合ISO 15403的压缩天然气。

ISO 14469-3:2006 applies to compressed natural gas (CNG) vehicle nozzles and receptacles constructed entirely of new, unused parts and materials. CNG fuelling connection nozzles consist of the following components, as applicable:

• receptacle and protective cap (mounted on vehicle);
• nozzle.

ISO 14469-3:2006 applies to devices which have a service pressure of 250 bar and refers only to a service pressure of 250 bar.This part of ISO 14469 applies to devices with standardized mating components and applies to connectors which:

• prevent natural gas vehicles from being fuelled by dispenser stations with service pressures higher than that of the vehicle;
• 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 14469-3:2006 is applicable to compressed natural gas in accordance with ISO 15403.
