Title
Hydraulic fluid power — Filters — Multi-pass method for evaluating filtration performance of a filter element
International Organization for Standardization
Publication Date:
Jun 15, 2008
Scope:
This International Standard describes the following:
a) a multi-pass filtration performance test 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 <= 25 µm(c), and a final
reservoir gravimetric level of less than 200 mg/L;
NOTE 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 ISO medium test dust contaminant and a test
fluid in accordance with Annex A.
This International Standard 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 International Standard applies to three test
conditions:
- test condition 1, with a base upstream gravimetric level
of 3 mg/L;
- test condition 2, with a base upstream gravimetric level
of 10 mg/L;
- test condition 3, with a base upstream gravimetric level
of 15 mg/L.
