ISO 16889:2008 describes a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements; a procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics; 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 less than or equal to 25 �m(c), and a final reservoir gravimetric level of less than 200 mg/L; and a test using ISO medium test dust contaminant and a test fluid. ISO 16889:2008 is intended to provide a test procedure that yields reproducible test data for appraising the filtration performance of a hydraulic fluid power filter element without influence of electrostatic charge. ISO 16889:2008 applies to three test conditions: test condition 1, conducted with a base upstream gravimetric level of 3 mg/L; test condition 2, conducted with a base upstream gravimetric level of 10 mg/L; and test condition 3, conducted with a base upstream gravimetric level of 15 mg/L.
