气瓶 - 柔性软管组件 - 规格和测试

[中文适用范围]： 本文件提供了用于连接气瓶、气瓶束或拖车（电池车辆）以及 MEGC 的高压柔性软管组件的规范和测试要求，用于在生产现场充装和排空气体时以及供客户使用。 本文件适用于额定压力高达 1000 bar、温度范围为 -40 °C 至 +65 °C 的柔性软管组件。 本文件不适用于： ——供客户使用的用于焊接、切割和相关工艺的橡胶和塑料柔性软管组件，压力高达 45 MPa (450 bar)（参见 ISO 14113）； ——供客户使用的医用气体系统用高压柔性软管组件（见 — 供客户使用的医用气体低压软管组件（见 ISO 5359）； ——用于焊接、切割和相关的橡胶和热塑性低压软管组件供客户使用的工艺（参见 ISO 3821 或 ISO 12170）； ——用于低温应用的柔性软管组件（参见 ISO 21012）； ——用于液化石油气（LPG）的柔性软管组件 注：通过所述型式试验批准的柔性软管组件设计本文件中规定的爆破压力与额定压力之比可能低于其他标准中规定的值。 [外文原描述]： This document provides specification and testing requirements for high pressure flexible hose assemblies intended to be connected to gas cylinders, bundles of cylinders or trailers (battery vehicles), and MEGCs for use when filling and emptying gas at production sites and also for customer use. This document applies to flexible hose assemblies with rated pressures up to 1 000 bar for use in the temperature range of −40 °C to +65 °C. This document is not applicable to: — rubber and plastics flexible hose assemblies for welding, cutting and related processes up to 45 MPa (450 bar) for customer use (see ISO 14113); — high pressure flexible hose assemblies for use with medical gas systems for customer use (see ISO 21969); — low pressure hose assemblies for use with medical gases for customer use (see ISO 5359); — rubber and thermoplastic low pressure hose assemblies for welding, cutting and related processes for customer use (see ISO 3821 or ISO 12170); — flexible hose assemblies for cryogenic applications (see ISO 21012); — flexible hose assemblies for liquid petroleum gas (LPG). NOTE Flexible hose assembly designs which pass the type test approval described in this document can have a lower ratio of burst pressure to rated pressure than stated in other standards.
