Hydraulic fluid power. Filter elements. Determination of resistance to flow fatigue using particulate contaminant Ingestion-build-67170 This version of BS 7121-41 Scope This International Standard specifies a method for determining the resistance of a hydraulic filter element to flow fatigue after it has been loaded with particulate contaminant and subjected to a uniform varying flow rate and predetermined maximum element differential pressure. It establishes a uniform method for verifying the ability of a filter element to withstand the flexing caused by cyclic differential pressures induced by a variable
