本文件规定了十类、四个等级和七种类型的钢丝或织物增强液压软管和软管组件的要求，标称尺寸从5到102.对于所有尺寸，每个等级都有一个最大工作压力。 它们适用于: —？ISO中定义的油基液压液HH、HL、HM、HR和HV6743？4温度范围为40？°C至+100°C，适用于AS、AC、BS和BC软管和来自40？°C至+120对于CS、CC和直流软管。 —？ISO中定义的水基流体HFC、HFAE、HFAS和HFB6743？4温度范围为40？°C至+70°C。 —？水的温度范围为0°C至+70°C。 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决定。 注意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。

This document specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure for all sizes. They are suitable for use with: —    oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743？4 at temperatures ranging from？40 °C to +100 °C for types AS, AC, BS and BC hoses and from？40 °C to +120 °C for types CS, CC and DC hoses. —    water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743？4 at temperatures ranging from？40 °C to +70 °C. —    water at temperatures ranging from 0 °C to +70 °C. This document does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components. NOTE       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.
