Hydraulic fluid power — Filter elements — Determination of resistance to flow fatigue using particulate contaminant

ISO 3724:2007 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 terminal 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 flow rate.
