标准范围
本文件规定了柔性燃料管路的测试和要求，柔性燃料管路是一种液化天然气燃料系统部件，用于ISO？3833.本文件不适用于下列情况:A）？燃料容器；b）？固定式燃气发动机；c）？容器安装硬件；d）？电子燃油管理；e）？加油容器。笔记？1？应认识到，可以检查本文未具体涵盖的各种组件以满足本文的标准，并根据适当的功能测试进行测试。笔记？2？除非另有说明，本文件中对压力的所有引用均被视为表压。笔记？3？本文件基于天然气作为燃料的工作压力为1.6？A(16？吧).（1？巴？=？0，1？兆帕？=？105？帕；？1？MPa？=？1？N/mm2。）其他工作压力可以通过适当的系数（比率）调节压力来适应。比如一个2？MPa（20？bar）工作压力系统将要求压力乘以1.25。
This document specifies tests and requirements for the flexible fuel lines, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. This document is not applicable to the following:
a) fuel containers;
b) stationary gas engines;
c) container mounting hardware;
d) electronic fuel management;
e) refuelling receptacles.
NOTE 1 It is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this document and tested according to the appropriate functional tests.
NOTE 2 All references to pressure in this document are considered gauge pressures unless otherwise specified.
NOTE 3 This document is based upon a working pressure for natural gas as a fuel of 1,6 MPa (16 bar). (1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.) Other working pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio). For example, a 2 MPa (20 bar) working pressure system will require pressures to be multiplied by 1,25.
