ISO 3724:2007
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 flow rate.
NOTE Annex A summarizes data from a round robin test performed to verify the procedure specified in this
International Standard.
