钢丝增强的橡胶和塑料软管及软管件 弯曲液压脉冲试验

[中文适用范围]： 本文件描述了在高脉冲压力和低脉冲压力下对橡胶或塑料液压软管组件进行弯曲的软管脉冲测试。 高压测试在大于3 MPa的压力下进行，低压测试在1.5 MPa至3 MPa的压力下进行。 该测试程序适用于产品要求中包含的在使用中承受脉动压力的液压软管组件。 注：不带弯曲的脉冲测试程序可在 ISO 6803 中找到。 [外文原描述]： This document describes hose impulse testing, with flexing, of rubber or plastics hydraulic hose assemblies at both high and low impulse pressures. The high-pressure testing is carried out at pressures greater than 3 MPa and the low-pressure testing at pressures from 1,5 MPa to 3 MPa. The test procedure is applicable to hydraulic hose assemblies that are subject to pulsating pressures in service which are included in the product requirements. NOTE Impulse test procedures without flexing can be found in ISO 6803.
