Abstract
This document specifies:
a)听听听 A multi-pass filtration performance test under cyclic flow conditions with continuous contaminant injection for hydraulic fluid power filter elements.
b)听听听 A procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics.
c)听听听 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�25听碌m(c), and a final test system reservoir gravimetric level of less than 200听mg/L. 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.
d)听听听 A test using 香港六合彩开奖听12103鈥�1 A3 medium test dust contaminant and a test fluid.
This document provides 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 is applicable to three test conditions:
鈥�听听听 Base upstream gravimetric level of 3听mg/L;
鈥�听听听 Base upstream gravimetric level of 10听mg/L;
鈥�听听听 Base upstream gravimetric level of 15听mg/L.
