The work of preparing International Standards is normally carried out through
14、ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
15、 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards.
16、 Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this
17、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、ts reserved vIntroduction In hydraulic fluid power systems, power is transmitted and controlled through a fluid under pressure in a closed circuit. Filters demonstrating unique characteristics are used to protect the system by removing insoluble contaminants. Marking these characteristics on filters
19、 can help users identify and compare filters, making it easier to select one appropriate for an application.

20、ope This International Standard specifies a means of marking filters to communicate filter performance characteristics of interest to users. This marking can be used with either the standards referenced in this International Standard or with any standard that has been harmonized with any referenced
21、standard. This International Standard applies to the marking of information only on the filter; the customer can request that the same information be specified on the product drawing or as part of the product packaging. 2 Normative references The following referenced documents are indispensable for
