[中文适用范围]： 本文件规定了公称尺寸为 6,3 至 51 的五种类型的螺旋钢丝增强液压软管和软管组件的要求。 它们适用于： ——油基液压油 HH、HL、HM、HR 和 HV根据 ISO 6743-4 的定义，4SP 和 4SH 型软管的温度范围为 -40 °C 至 +100 °C，R12、R13 和 R15 型软管的温度范围为 -40 °C 至 +120 °C； ——ISO 6743-4 中定义的水基液体 HFC、HFAE、HFAS 和 HFB，温度范围为 -40 °C 至 +70 °C； ——温度范围为 0 °C 至 +70 °C 的水。 本文件不包括端部配件的要求。 它仅限于软管和软管组件的要求。 注：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 five types of spiral-wire-reinforced hydraulic hoses and hose assemblies of nominal size from 6,3 to 51. 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 4SP and 4SH hoses and from −40 °C to +120 °C for types R12, R13 and R15 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 end fittings. It is limited to requirements for hoses and hose assemblies. 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.
