道路车辆.压缩天然气(CNG)燃料系统部件.第20部分:非不锈钢制的硬质燃料管线

[中文适用范围]： ISO 15500 的这一部分提供了适用于碳钢刚性燃油管路的具体要求和测试，旨在用于 ISO 3833 中定义的机动车辆类型，天然气作为燃料的工作压力为 20 MPa（ 200 bar）在 15 °C 下稳定。 ISO 15403-1 中规定（单燃料、双燃料或双燃料应用）。 ISO 15500 的本部分不适用于以下内容： a) 位于汽化器上游（包括汽化器）的液化天然气（LNG）燃料系统组件； b) 燃料容器； c) 固定式燃气发动机； d) 容器安装硬件； e) 电子燃油管理； f) 加油容器。 注：除非另有说明，ISO 15500 本部分中所有提及的压力均视为表压。 1) [外文原描述]： ISO 15500-20:2015 provides specific requirements and tests applicable to the rigid fuel line in carbon steel, intended for use on the types of motor vehicles, as defined in ISO 3833, with a service pressure for natural gas as a fuel of 20 MPa (200 bar) settled at 15 °C. ISO 15500 is intended to be applied to vehicles using natural gas which comply with requirements established in ISO 15403‑1 (mono-fuel, bi-fuel, or dual-fuel applications). This part of ISO 15500 does not apply to the following: a) liquefied natural gas (LNG) fuel system components located upstream of, and including, the vaporizer; b) fuel containers; c) stationary gas engines; d) container mounting hardware; e) electronic fuel management; f) refuelling receptacles. NOTE All references to pressure in this part of ISO 15500 are considered gauge pressures unless otherwise specified.[1] [1] 1 bar = 100 kPa = 0,1 MPa.
