Defines: - 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 ISO14085 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 ISO14085 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 ISO14085 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 ISO14085 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 ISO14085 can be used to compare the performance of aerospace hydraulic filter elements.
