BS ISO 15500-1:2015规定了压缩天然气燃料的一般要求和定义 系统组件，用于ISO 3833中定义的机动车辆类型。它也 提供一般设计原则，并规定说明和标记要求。ISO 15500的本部分适用于使用 符合ISO 15403-1标准的天然气。不适用于以下情况:位于蒸发器上游的液化天然气（LNG）燃料系统部件，包括蒸发器；燃料容器；固定式燃气发动机；集装箱安装硬件；电子燃料管理；加油容器。注1:应认识到，本文中未具体涵盖的其他组件可通过以下方式进行检查: 符合ISO 15500本部分的标准，并根据适当的功能测试进行测试。 注2:ISO 15500本部分中提及的所有压力均应视为表压，除非 另有规定。注3:ISO 15500的本部分基于20 MPa[200 bar1]的天然气燃料使用压力 在15°C下沉降。通过适当的系数调整压力，可以调节其他工作压力 （比率）。例如，25兆帕（250巴）的工作压力系统需要将压力乘以1,25。交叉引用:ISO 6722-1ISO 6722-2ISO 15500-2ISO 15500-3ISO 15501-1ISO 3833ISO 50448-1ISO 15403-1ISO/TR 15403-2ANSI/ASME B1。1:2003购买本文件时，所有当前可用的修订都包括在购买本文件中。

BS ISO 15500-1:2015 specifies general requirements and definitions of compressed natural gas fuel system components, 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 part of ISO 15500 is applicable to vehicles (mono-fuel, bi-fuel, or dual-fuel applications) using natural gas in accordance with ISO 15403-1. It is not applicable to the following:liquefied natural gas (LNG) fuel system components located upstream of, and including, the vaporizer;fuel containers;stationary gas engines;container mounting hardware;electronic fuel management;refuelling receptacles.NOTE 1 It is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this part of ISO 15500 and tested according to the appropriate functional tests.NOTE 2 All references to pressure in this part of ISO 15500 are to be considered gauge pressures unless otherwise specified.NOTE 3 This part of ISO 15500 is based upon a service pressure for natural gas as fuel of 20 MPa [200 bar1)] settled at 15 °C. Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio). For example, a 25 MPa (250 bar) service pressure system will require pressures to be multiplied by 1,25.Cross References:ISO 6722-1ISO 6722-2ISO 15500-2ISO 15500-3ISO 15501-1ISO 3833ISO 50448-1ISO 15403-1ISO/TR 15403-2ANSI/ASME B1.1:2003All current amendments available at time of purchase are included with the purchase of this document.
