本文件规定了三种织物增强热塑性塑料软管和标称尺寸为3,2至25的软管组件的要求。根据导电性要求，每种类型分为两类。 它们适用于: -ISO 6743-4中定义的油基液压油HH、HL、HM、HR和HV，温度范围为-40°C至+93°C； -ISO 6743-4中定义的水基流体HFC、HFAE、HFAS和HFB，温度范围为0°C至+60°C -温度在0°C至+60°C之间的水。 本文件不包括对端部配件的任何要求。它仅限于软管和软管组件的性能。 注:用户有责任与软管制造商协商，确定软管与所用流体的相容性。

This document specifies requirements for three types of textile-reinforced thermoplastics hoses and hose assemblies of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements. 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 +93 °C; — water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743？4 at temperatures ranging from 0 °C to +60 °C — water at temperatures ranging from 0 °C to +60 °C. This document does not include any requirements for end fittings. It is limited to the performance of 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.
