DYNAMIC TEST METHOD FOR DETERMINING THE DEGREE OF CLEANLINESS OF THE DOWNSTREAM SIDE OF FILTER ELEMENTS

Scope
This test method describes a procedure for determining the insoluble contamination level of the downstream side of filter elements. Results of this procedure represent the particulate release rate of the tested filter element under the prevailing conditions of the test and may be used for comparative evaluation of the effectiveness of various cleaning methods or cleanliness of elements as received from manufacturers. Because of the variety of conditions which may exist even under the provisions of this procedure, it is difficult to correlate data from one testing agency to another. The data obtained by this procedure do not necessarily indicate qualitatively or quantitatively, the contamination which may be released by a filter element into the operating fluid during service. When properly conducted, however, the procedure will show marked differences between various cleanliness levels of filter elements. Because of the probability of extraneous contamination caused by conducting this test in an uncontrolled atmosphere, all operations should be conducted in an environment equivalent to that for FED-STD-209, Class 100,000.

Issuing Committee
A-6C1 Fluids and Contamination Control Committee
A6C1 is responsible for the development of standards, processes, and practices related to Aerospace Fluids and Systems' cleanliness in aerospace engines, hydraulic systems and missiles, and the integration of these components for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, and suppliers to exchange technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
