【摘要】: This part of ISO 4548specifies a multi-pass filtration test with continuous contaminant injectionand using the on-line particle counting method for evaluating the performanceof full-flow lubricating oil filters for internal combustion engines.The testprocedure determines the contaminant capacity of a filter, its particulateremoval characteristics and differential pressure.This test is intended forapplication to filter elements having a rated flow between 4 l/min and 600l/min and with an efficiency of less than 99 % at a particle size greater than10 μm.NOTE Several test flow loops built into one testrig, or several test rigs, would be required to cover the complete flow rangeof 4 l/min to 600 l/min.

【摘要】: This International Standarddescribes the following:a) a multi-pass filtration performance test withcontinuous contaminant injection for hydraulic fluid power filter elements;b) aprocedure for determining the contaminant capacity, particulate removal anddifferential pressure characteristics;c) a test currently applicable tohydraulic fluid power filter elements that exhibit an average filtration ratiogreater than or equal to 75 for particle sizes ~< 25 pm(c), and a finalreservoir gravimetric level of less than 200 mg/L;NOTE It is necessary todetermine by validation the range of flow rates and the lower particle sizelimit that can beused in test facilities.d) a test using ISO medium test dustcontaminant and a test fluid in accordance with Annex A.This InternationalStandard is intended to provide a test procedure that yields reproducible testdata forappraising the filtration performance of a hydraulic fluid power filterelement without influence of electrostaticcharge.This International Standardapplies to three test conditions:-- test condition 1, with a base upstreamgravimetric level of 3 mg/L;-- test condition 2, with a base upstreamgravimetric level of 10 mg/L;-- test condition 3, with a base upstreamgravimetric level of 15 mg/L.
