This document specifies:
a) A multi-pass filtration performance test under cyclic flow conditions 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 ≤25µm(c), and a final test system reservoir gravimetric level of less than 200mg/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) A test using ISO12103-1 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:
1) Base upstream gravimetric level of 3mg/L.
2) Base upstream gravimetric level of 10mg/L.
3) Base upstream gravimetric level of 15mg/L.
