Aerospace series. Hydraulic filter elements. Test methods - Verification of collapse/burst pressure rating Ingestion-build-209208 Those manufacturing spheroidal graphite case1 Scope This part of ISO 14085 describes a method for verifying the collapse burst pressure rating of an aerospace hydraulic fluid power filter element. This represents the capability of a filter element to withstand a designated differential pressure in the normal (intended) direction of flow, created by flowing contaminated fluid through the filter element until either collapse burst occurs or the maximum expected differential pressure is reached
