标准范围

本文件规定了液化石油气燃料部件的一般要求和定义（燃料选择系统和电气装置，用于ISO 3833定义的机动车辆）。它还提供了一般设计原则，并规定了说明和标记的要求。本文件适用于根据ISO 9162使用气体燃料的车辆（单燃料、双燃料或双燃料应用）。不适用于下列情形:A）？燃料容器；b）？固定式燃气发动机；c）？容器安装硬件；d）？加油容器。应当认识到，可以检查本文未具体提及的各种部件是否符合ISO 20766系列的任何适用部分的标准，包括对适当功能测试的测试。除非另有说明，本文件中对压力的所有引用均被视为表压。本文件适用于工作压力在110？kPa（富含丁烷在20？°C）和840？kPa(在20℃下富含丙烷)，以下在本文件中称为。可以通过按适当的系数（比率）调节压力来适应其他工作压力。

This document specifies general requirements and definitions of liquefied petroleum gas fuel components (fuel selection system and electrical installations, intended for use on the types of motor vehicles as defined in ISO 3833).

It also provides general design principles, and specifies requirements for instructions and marking.

This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using gaseous fuels in accordance with ISO 9162. It is not applicable to the following:

a)       fuel containers;

b)       stationary gas engines;

c)        container mounting hardware;

d)       refuelling receptacles.

It is recognized that miscellaneous components not specifically addressed herein can be examined for compliance with the criteria of any applicable part of the ISO 20766 series, including testing to the appropriate functional tests.

All references to pressure in this document are considered gauge pressures unless otherwise specified.

This document applies to devices which have a service pressure in the range of 110 kPa (butane rich at 20 °C) and 840 kPa (propane rich at 20 °C), hereinafter referred to in this document. Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).
