Тезис

This part of ISO 22056 describes a method for verifying the collapse/burst pressure rating of an aerospace lubricant fluid filter element. This represents the capability of a filter element to withstand a designated differential pressure in the normal (intended) direction of flow, created by flowing contaminated lubricant fluid through the filter element until either collapse/burst occurs or the maximum expected differential pressure is reached without filter element failure. The collapse/burst pressure test can be conducted as a continuation of an efficiency test performed according to ISO 22056-3 or as a continuation of a dirt holding capacity test performed according to ISO-22056-4. This can be achieved by continuing the contaminant injection until the designated filter element differential pressure is reached. This test procedure describes the laboratory conditions for tests and will need to be augmented by system level testing including actual conditions of use, for example the operating fluid or contamination. The test data resulting from application of this part of ISO 22056 can be used to compare the performance of aerospace lubricant filter elements.
