Hydraulic fluid power -- Filter elements -- Determination of resistance to flow fatigue using high viscosity fluid
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
ISO 23181:2007 specifies a method for determining the resistance of a hydraulic filter element to flow fatigue when subjected to high viscosity fluid, using a uniformly varying flow rate up to a predetermined terminal differential pressure and a controlled waveform.
It establishes a method for verifying the ability of a filter element to withstand the flexing caused by cyclic differential pressures induced by a variable flow rate.
