ISO 16889-Hydraulic fluid power — Filters — Multi-pass method for evaluating filtration performance of a filter element
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 u 25 µm(c), and a final reservoir gravimetric level of less than 200 mg/L
You choose the micron size particles you would like to test the efficiency for
You choose the flowrate, fluid type, contaminant, and reporting units
Send us your filters, filter media, or flat sheet media
Send us your filter housing if available
We can help you with any questions you have to ensure the testing meets your or your client’s needs
This test can be customized for any special requirements you may have
