This International Standard describes hose impulse testing, without 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 with flexing can be found in ISO 6802, Rubber and plastics hoses and hose assemblies with wire reinforcements — Hydraulic impulse test with flexing.
