Each member body interested in a subject for which a technical committee has been established has the right to be represented on tha
14、t committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in a
15、ccordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard re

18、 2941:2009(E) ISO 2009 All rights reserved vIntroduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Filters maintain the cleanliness of fluid in a fluid power system by removing insoluble contaminants. A filter el
19、ement is the porous device that performs the actual process of filtration. The capability of the filter element to maintain a specified fluid cleanliness level depends on its performance and structural integrity and its ability to withstand non-steady-state conditions (e.g. cold starts and decompres
20、sion surges). The filter elements resistance to collapse or burst is a measure of its ability to withstand such effects.

21、 rating 1 Scope This International Standard specifies a method for verifying the collapse/burst pressure rating of a hydraulic fluid power filter element, i.e. the capability of a filter element to withstand a designated differential pressure at the normal (i.e., intended direction of) flow, by mean
22、s of pumping contaminated fluid through the filter element until either collapse/burst occurs or the maximum expected differential pressure is reached without element failure. 2 Normative references The following referenced documents are indispensable for the application of this document.
