标准范围

本文件规定了标称尺寸为3.2至25的两种增强软管和软管组件的要求，具体取决于最小爆破压力与最大工作压力的关系。每种类型根据最大工作压力分为不同的类别。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+100°C；-？温度在0°C至+70°C范围内的水基液体HFC、HFAE、HFAS和HFB，如ISO？6743-4所定义；-？温度在0摄氏度至+70摄氏度之间的水。此类软管和软管组件拟用于:-？喷水和喷水应用；-？液压应用。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性能。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相容性。注2:对于带有手动泵的液压千斤顶，可以使用符合ISO 16301的软管和软管组件。

This document specifies requirements for two types of reinforced hoses and hose assemblies of nominal size from 3,2 to 25, dependent on relation of minimum burst pressure to maximum working pressure. Each type is divided into classes dependent on maximum working pressure.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 0 °C to +70 °C;—    water at temperatures ranging from 0 °C to +70 °C.Such hoses and hose assemblies are intended to be used for:—    water jetting and water blasting applications;—    hydraulic applications.This document does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.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   For hydraulic jacks with manually driven pumps, hoses and hose assemblies per ISO 16301 can be used.
