标准范围

本文件规定了用于ISO 3833中定义的机动车类型的液化天然气燃料系统部件的性能和一般试验方法。本文件适用于根据ISO 15403系列使用液化气的车辆（单燃料、双燃料或双燃料应用）。不适用于以下情况:原始生产和改装车辆。本文件仅适用于“LNG系统”中的部件，即部件（油箱、阀门、柔性燃油管路等）和连接部件（燃油管路、配件等）的组装。)安装在推进系统中使用液化天然气的机动车上，相关部件包括汽化器。蒸发器下游的其他部件被视为ISO 15501中涵盖的CNG部件。注:除非另有规定，否则以兆帕和巴（1巴=0,1兆帕=105帕；1兆帕=1 N/mm2）为单位的所有参考压力均视为表压。

This document specifies performance and general test methods for liquefied natural gas fuel system components intended for use on the types of motor vehicles defined in ISO 3833.This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using liquefied gas in accordance with the ISO 15403 series. It is not applicable to the following: original-production and converted vehicles.This document is only applicable on the components in the "LNG system" meaning an assembly of components (tanks, valves, flexible fuel lines, etc.) and connecting parts (fuel lines, fittings, etc.) fitted on motor vehicles using LNG in their propulsion system and related components up to and including the vaporizer. Other parts downstream from the vaporizer are considered as CNG components covered by ISO 15501.NOTE All references to pressures, given in megapascals and bar (1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2) are considered gauge pressures, unless otherwise specified.
