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

1996-05-01

HISTORICAL

ARP599

This test method describes a procedure for determining the insoluble contamination level of the downstream side of filter elements. Results of this procedure are intended to be used only for evaluation of the effectiveness of various cleaning treatments, or cleanliness of element as received from manufacturers. The data obtained by this procedure do not necessarily indicate, qualitatively or quantitatively, the contamination which may be released by a filter element into a fluid during service use. Because of the wide variety of conditions which may exist in service applications, it is recommended that the user design and conduct his own particular service performance test. (See paragraph 10.1).

ARP599A

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.

This SAE Aerospace Information Report (AIR) presents data on normally accepted changes in physical properties and contamination levels for military hydraulic fluids used in hydraulic test stands. This information is of importance to all users of hydraulic test stands to assure the performance data obtained on these test stands for specific components will not be adversely affected by excessive changes in fluid properties or contamination levels. The data pertains to fluids conforming to specifications MIL-PRF-5606, MIL-PRF-83282, and MIL-PRF-87257. The guidelines incorporated in the AIR are the general consensus values of knowledgeable professionals. However, the experience and judgment of engineers and operators responsible for the equipment must be relied upon to determine when the hydraulic fluid is to be replaced.
