标准范围
This part of ISO 14085 describes a method for verifying the collapse/burst pressure rating of anaerospace hydraulic fluid power filter element. This represents the capability of a filter element towithstand a designated differential pressure in the normal (intended) direction of flow, created byflowing contaminated fluid through the filter element until either collapse/burst occurs or the maximumexpected differential pressure is reached without element failure.The collapse/burst pressure test can be conducted in conjunction with an efficiency test performedaccording to the procedure defined in the ISO 14085-3 by continuing the contaminant injection until thedesignated filter element differential pressure is reached.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 conditionsof use, for example the operating fluid or contamination.The tests data resulting from application of this part of ISO 14085 can be used to compare the performanceof aerospace hydraulic filter elements.
