橡胶软管和软管组件.油基或水基液体用钢丝编织增强液压型.规范

[中文适用范围]： 本文件规定了六种公称尺寸从5到51的钢丝编织增强软管和软管组合件的要求。本文件还规定了2SN和R2AT类型的公称尺寸63软管，以及2SN类型的公称尺寸76软管。 它们适用于： - 在-40°C至+100°C温度范围内，使用ISO 6743-4中定义的HH、HL、HM、HR和HV油基液压流体； - 在-40°C至+70°C温度范围内，使用ISO 6743-4中定义的HFC、HFAE、HFAS和HFB水基流体； - 在0°C至+70°C温度范围内使用水。 本文件不适用于连接端。它仅限于软管和软管组合件的性能。 注1：软管组合件的最大工作压力取决于其组件中的最低最大工作压力。 注2：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。 [外文原描述]： This document specifies requirements for six types of wire-braid-reinforced hoses and hose assemblies of nominal size from 5 to 51. This document also specifies the hose of nominal size 63 for types 2SN and R2AT, and the hose of nominal size 76 for type 2SN. 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; 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 apply to the connection ends. It is limited to the performance of hoses and hose assemblies. NOTE 1 The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components. NOTE 2 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.
