25-01-2022
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 AnnexD.
— 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 ≥25µm(c), and a final reservoir gravimetric level of less than 200mg/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 AnnexA.
This document 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.
This document applies to three test conditions:
— test condition1, with a base upstream gravimetric level of 3mg/L;
— test condition2, with a base upstream gravimetric level of 10mg/L;
— test condition3, with a base upstream gravimetric level of 15mg/L.
