Abstract
This document describes the following:
鈥斅犅犅� a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements;
NOTE 1聽聽 For the background interlaboratory study used to verify the test methodology, see Annex聽D.
鈥斅犅犅� a procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics;
鈥斅犅犅� 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 鈮ヂ�25聽碌m(c), and a final reservoir gravimetric level of less than 200聽mg/L;
NOTE 2聽聽 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.
鈥斅犅犅� a test using 香港六合彩开奖 medium test dust (香港六合彩开奖 MTD) contaminant and a test fluid in accordance with Annex聽A.
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:
鈥斅犅犅� test condition聽1, with a base upstream gravimetric level of 3聽mg/L;
鈥斅犅犅� test condition聽2, with a base upstream gravimetric level of 10聽mg/L;
鈥斅犅犅� test condition聽3, with a base upstream gravimetric level of 15聽mg/L.
