ISO 14085-5:2015 航空航天系列液压过滤元件试验方法第5部分：抗流动疲劳

This part of ISO 14085 specifies a method for determining the resistance of a filter element to flow fatigue caused by varying flow through the filter in various stages of the filter contaminant loading process. The filter is subjected to a uniform varying flow rate for a specified number of cycles, at a number of predetermined differential pressures. Although the number of cycles and differential pressure conditions used in this part of ISO 14085 is meant to simulate possible service conditions, this part of ISO 14085 is not intended to qualify a filter element under replicate conditions of service; this can only be done by a specific test protocol developed for the purpose, including actual conditions of use, for example the operating fluid, contamination, and exact cyclic flow conditions. This part of ISO 14085 establishes a method for verifying the ability of a filter element to withstand the stress caused by cyclic differential pressures induced by a variable flow rate. The test data resulting from application of this part of ISO 14085 can be used to compare the performance of aerospace hydraulic filter elements.

ISO 14085-2:2015 航空航天系列液压过滤元件试验方法第2部分：调节

This part of ISO 14085 specifies — a procedure to thermally condition a hydraulic filter element to presumed aerospace hydraulic system stresses, — a test procedure to complete cold soaks, hot soaks, and temperature variation in a combined manner, and — a test procedure to simulate cold starts. This part of ISO 14085 is not intended to qualify a filter element under replicate conditions of service; this can only be done by a specific test protocol developed for the purpose, including actual conditions of use, for example the operating fluid or contamination. This part of ISO 14085 is intended to provide a test procedure that yields reproducible thermal test conditioning of a hydraulic filter element, for simulation of the thermal stresses typically encountered in an aerospace hydraulic system. The conditioning test procedures defined in this part of ISO 14085 are intended to be used prior to performance tests as specified in other parts of this International Standard. The tests data resulting from application of this part of ISO 14085 can be used to compare the performance of aerospace hydraulic filter elements.

ISO 14085-6:2015 航空航天系列液压过滤元件试验方法第6部分：初始清洁度

This part of ISO 14085 defines a reference method for determining the level of cleanliness of new filter elements for use in aircraft hydraulic systems, after production prior to shipment, or prior to installation in the circuit. It applies to filter elements used on systems requiring fluid cleanliness conditions defined in the particular specification. The tests data resulting from application of this part of ISO 14085 can be used to compare the cleanliness of aerospace hydraulic filter elements.
