标准范围
本文件规定了在？40°C至65°C的工作温度范围内，适用于分配标称工作压力高达70 MPa氢气的钢丝或织物增强软管和软管组件的要求。本文件包含氢燃料站气态氢软管和软管组件的材料、设计、制造和测试的安全要求。不在本文件范围内的软管和软管组件如下:1） 作为车辆高压车载燃油存储系统的一部分，2） 用作车辆低压燃油输送系统的一部分，以及3） 柔性金属软管。注1:本文件主要用于将高压氢气从加油分配器分配到氢气车辆的软管和软管组件。ISO 16964规定了用于将氢气从可运输容器（如拖车）输送至电站缓冲存储器的软管要求。注2:软管组件包括两端带有接头的软管（见图1）。每个连接器有两个基本功能元件，如下所述:1） 连接到软管上。该功能由要求定义，并通过本文件中基于性能的测试进行验证（以及软管本身）。2） 用于过渡和连接到管道系统或设备的配件。该功能通过参考适当的氢气设备标准和管道规范来实现。
This document specifies the requirements for wire or textile reinforced hoses and hose assemblies suitable for dispensing hydrogen up to 70 MPa nominal working pressure, in the operating temperature range of？40 °C to 65 °C.This document contains safety requirements for material, design, manufacture and testing of gaseous hydrogen hose and hose assemblies for hydrogen fuelling stations.Hoses and hose assemblies excluded from the scope of this document are the following:1) those used as part of a vehicle high pressure on-board fuel storage system,2) those used as part of a vehicle low pressure fuel delivery system, and3) flexible metal hoses.NOTE 1 This document was developed primarily for hoses and hose assemblies for dispensing high pressure hydrogen from refuelling dispensers to hydrogen vehicles. Requirements for hoses used to deliver hydrogen from a transportable vessel (e.g. trailer) into a buffer storage of a station are addressed in ISO 16964.NOTE 2 Hose assemblies include the hose with connectors on each end (see Figure 1). Each connector has two basic functional elements that are addressed as described below:1) Coupling to hose. This function is defined by requirements and verified (along with the hose itself) by performance-based tests in this document.2) Fitting for transition and connection to the piping system or equipment. This function is addressed by reference to appropriate hydrogen equipment standards and piping codes.
