Diesel Filter The diesel filter shall be tested as follows according to ISO4020 standard (test method for fuel filter for road vehicle-Automobile diesel engine).
(1) The new filter clearance test determines whether the inside of the filter core has cleared the residual dust and impurities in the production, storage and transportation.
(2) The bubble test is used to verify whether the filter element has pores greater than the filtration accuracy.
(3) Filtration efficiency and Life test Filtration efficiency refers to the percentage of specific particles being filtered, and the life of the filter is expressed as the time when the plugging test pressure difference is greater than 0.07mpa.
(4) Water separation validity test to determine the percentage of water in the oil-water mixture separated by the oil filter.
(5) The filter element damage test determines the anti-fracture pressure of the filter element.
(6) Filter assembly damage test to determine the capacity of the assembly to withstand internal pressure.
(7) The pulsating pressure fatigue test determines the mechanical strength of the filter assembly at pulsating pressure (simulating the start or stop of the engine).
(8) Vibration fatigue test to determine the mechanical strength of the oil filter against vibration under normal service conditions.
