道路车辆.液化石油气燃料系统部件.第2部分:性能和一般试验方法

[中文适用范围]： 本文件规定了液化石油气燃料系统部件的性能和一般测试方法，旨在用于 ISO 3833 中定义的机动车辆类型。 本文件适用于车辆（单燃料、双燃料或双燃料应用） ) 根据 ISO 9162 使用液化石油气。 它不适用于以下容器： 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。 注 1：公认的是，可以检查本文中未具体提及的各种组件是否符合 ISO 20766 任何适用部分的标准，包括测试适当的功能测试。 注 2：除非另有说明，本文件中所有提及的压力均视为表压。 注 3：本文件适用于工作压力在 110 kPa（20 °C 时富丁烷）和 840 kPa（20 °C 时富丙烷）范围内的设备，下文将提及本文件。 通过适当的系数（比率）调整压力可以适应其他工作压力。 [外文原描述]： This document specifies performance and general test methods of liquefied petroleum gas fuel system components, intended for use on the types of motor vehicles as defined in ISO 3833. This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using liquefied petroleum gas in accordance with ISO 9162. It is not applicable to the following: a) fuel containers; b) stationary gas engines; c) container mounting hardware; d) electronic fuel management; and e) refuelling receptacles. NOTE 1 It is recognized that miscellaneous components not specifically addressed herein can be examined for compliance with the criteria of any applicable part of ISO 20766, including testing 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 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).
