This document 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 document describes two test methods. When there is not a requirement stated in the product standards, it is intended to 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.
