氢燃料车辆用气态氢燃料系统部件 第1部分:陆地车辆

[中文适用范围]： 本标准规定了用于氢燃料电池车的燃料系统组件的要求，涵盖了陆地车辆的相关规范。具体包括但不限于一般构造与组装、材料要求、服务温度、设计寿命、失效模式和影响分析（FMEA）、电气设备和布线、部件文献等。此外还详细描述了各种测试方法和技术要求，如静压强度、泄漏、超扭矩抵抗、弯曲力矩等。 [外文原描述]： This document establishes requirements for newly produced compressed hydrogen gas fuel system components, as listed below, that are intended for use on hydrogen gas powered land vehicles: a) check valves (see Clause 8); b) manual valves (see Clause 9); c) manual container valves (see Clause 10); d) automatic valves and automatic container valves (see Clause 11); e) hydrogen injectors (see Clause 12); f) pressure sensors, temperature sensors, and pressure gauges (see Clause 13); g) pressure regulators (see Clause 14); h) pressure relief valves (PRV) (see Clause 15); i) pressure relief devices (PRD) (see Clause 16, and refer to ISO 19882); j) excess flow valves (see Clause 17); k) gastight housing and leakage capture passages (see Clause 18); l) rigid fuel lines (see Clause 19); m) flexible fuel lines, hoses, and hose assemblies (see Clause 20); n) filter assemblies (see Clause 21); o) fittings (see Clause 22); p) non-metallic, low-pressure rigid fuel lines (see Clause 23); q) discharge line closures (see Clause 24). NOTE Other components not specifically identified here can be examined to meet the criteria of ISO 19887-1 and tested according to the appropriate functional needs. This document applies to components that have a nominal working pressure, as specified by the manufacturer, of 25 MPa, 35 MPa, 50 MPa, or 70 MPa at 15 °C, referred to in this document as the following pressure classes: a) “H25” – 25 MPa; b) “H35” – 35 MPa; c) “H50” – 50 MPa; and d) “H70” – 70 MPa. Other nominal working pressures for hydrogen gas besides those defined can be used if the qualification test requirements of this document are met. This document also applies to components downstream of the first stage of pressure reduction with a maximum operating pressure designated by the manufacturer in MPa or kPa. This document does not apply to the following: a) hydrogen gas fuel system components incorporated during the manufacture of motor vehicles originally manufactured in compliance with the international regulations on hydrogen and fuel cell vehicles, such as UN GTR No. 13, UN Regulation No. 134, UN Regulation No. 146, or IEC 62282-4-101; b) fuel containers; c) stationary power generation applications; d) container mounting hardware; e) electronic fuel management; f) refuelling receptacles; or g) components intended for liquid hydrogen.
