適用范圍：This International Standard describes the following:a) a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements;b) a procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics;c) a test currently applicable to hydraulic fluid power filter elements that exhibit an average filtration ratio greater than or equal to 75 for particle sizes ~< 25 pm(c), and a final reservoir gravimetric level of less than 200 mg/L;NOTE It is necessary to determine by validation the range of flow rates and the lower particle size limit that can beused in test facilities.d) a test using ISO medium test dust contaminant and a test fluid in accordance with Annex A.This International Standard is intended to provide a test procedure that yields reproducible test data forappraising the filtration performance of a hydraulic fluid power filter element without influence of electrostaticcharge.This International Standard applies to three test conditions:-- test condition 1, with a base upstream gravimetric level of 3 mg/L;-- test condition 2, with a base upstream gravimetric level of 10 mg/L;-- test condition 3, with a base upstream gravimetric level of 15 mg/L.
