scope:

This International Standard describes a pressure impulse test with flexing for rubber or plastics hydraulic hoses and hose assemblies. The test is applicable to high-pressure hydraulic hoses and hose assemblies, which are subject to pulsating pressure in service. This standard describes two test methods. When there is not a requirement stated in the product standards, use Method 1. Both test methods can be run with the option of the cool down test. NOTE The method of a pressure impulse test is described in ISO 6803, Rubber or plastics hoses and hose assemblies - Hydraulic-pressure impulse test without flexing.
