标准范围
This part of ISO 14085 specifies a method for determining the resistance of a filter element to flowfatigue caused by varying flow through the filter in various stages of the filter contaminant loadingprocess. The filter is subjected to a uniform varying flow rate for a specified number of cycles, at anumber of predetermined differential pressures.Although the number of cycles and differential pressure conditions used in this part of ISO 14085 ismeant to simulate possible service conditions, this part of ISO 14085 is not intended to qualify a filterelement under replicate conditions of service; this can only be done by a specific test protocol developedfor the purpose, including actual conditions of use, for example the operating fluid, contamination, andexact cyclic flow conditions.This part of ISO 14085 establishes a method for verifying the ability of a filter element to withstand thestress 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 performanceof aerospace hydraulic filter elements.
