3. The full-flow oil filter shall be tested in accordance with ISO4548.
(1) Pressure drop-flow characteristic Test Determine the pressure drop-flow curve of the filter assembly with an oil of the specified viscosity.
(2) Characteristic test of filter element bypass element to determine the filter element pressure drop - bypass flow curve. When the pressure drop through the filter element is low, in order to limit the amount of unfiltered oil, the bypass element is allowed to have a small amount of oil leakage below the specified opening pressure drop; When the filter element is completely blocked, it can bypass all the flow and not exceed the specified pressure drop.
