BS ISO 16889:2022 PDF

Scope: 1 Scope This document describes the following: — a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements; NOTE 1 For the background interlaboratory study used to verify the test methodology, see Annex D. — 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 ≥ 25 µm(c), and a final reservoir gravimetric level of less than 200 mg/L; NOTE 2 It is necessary to determine by validation the range of flow rates and the lower particle size limit that can be used in test facilities. — a test using ISO medium test dust (ISO MTD) contaminant and a test fluid in accordance with Annex A. This document is intended to provide a test procedure that yields reproducible test ...
