手动液压千斤顶用钢丝或纺织增强橡胶和塑料软管和软管组件规范

[中文适用范围]： 本文件规定了公称尺寸为 5 至 25 的三类钢丝或织物增强液压软管和软管组件的要求。 这些软管和软管组件用于带有手动操作手动泵的液压千斤顶应用。 它们适用于温度范围为 -40 °C 至 +55 °C 的液压油 HH、HL、HM、HR 和 HV。 对于需要重型服务的工具（例如救援工具），适用 ISO 19718[3]。 本文件不包括连接端的要求。 它仅限于软管和软管组件的性能。 软管总成的最大工作压力由部件的最低最大工作压力来调节。 注 1：用户有责任与软管制造商协商确定软管与所用流体的兼容性。 注2 对于液压千斤顶和工具应用的软管有两个国际标准，即注3 HH、HL、HM、HR 和HV 的分类见ISO 6743-4[2]。 [外文原描述]： ISO 16301 specifies the requirements for three classes of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 25. The hoses and hose assemblies are used in hydraulic jack applications with manually operated hand pumps. They are suitable for use with hydraulic fluids HH, HL, HM, HR and HV at temperature ranging from −40 °C to +55 °C. For tools that require heavy duty services such as a rescue tool, ISO 19718 [3] applies. ISO 16301 does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The maximum working pressure of hose assemblies is regulated by the lowest maximum working pressure of the components. NOTE 1 It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used. NOTE 2 There are two International Standards for hoses for hydraulic jacks and tool applications, i.e. ISO 16301 and ISO 19718. The comparison table is given in Annex A. NOTE 3 The classification of HH, HL, HM, HR and HV is found in ISO 6743-4 [2] .
