本文件提供了高压软管总成的规范和测试要求，这些软管总成拟连接到气瓶、成捆的气瓶或拖车（电池车）以及MEGC上，以供在生产现场加注和排空气体时使用，也可供客户使用。本文件适用于额定压力高达1000巴的柔性软管组件，用于温度范围为-40°C至+65°C的场合。 本文件不适用于: -客户使用的焊接、切割和相关工艺用橡胶和塑料软管组件，压力不超过45 MPa（450 bar）（见ISO 14113）； -与客户使用的医用气体系统一起使用的高压软管组件（见ISO 21969）； -与客户使用的医用气体一起使用的低压软管组件（见ISO 5359）； -客户使用的焊接、切割和相关工艺用橡胶和热塑性低压软管组件（见ISO 3821或ISO 12170）； -低温应用的挠性软管组件（见ISO 21012）； -液化石油气（LPG）用柔性软管组件。 注:通过本文件所述型式试验认证的软管总成设计的爆破压力与额定压力之比可能低于其他标准中的规定。

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.
