scope:

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.
