標準簡介
Specifies 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 [mu]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.
