9、Bibliography 6BS ISO 4548-7:2012ISO 4548-7:2012(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each
10、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 closely with the International
11、 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. Draft International Standards ad
12、opted 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 document may be the subject of pat
13、ent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 4548-7 was prepared by Technical Committee ISO/TC 70, Internal combustion engines, Subcommittee SC 7, Tests for lubricating oil filters.This second edition cancels and replaces the first edition (ISO 4548
14、-7:1990), which has been technically revised.ISO 4548 consists of the following parts, under the general title Methods of test for full-flow lubricating oil filters for internal combustion engines: Part 1: Differential pressure/flow characteristics Part 2: Element by-pass valve characteristics Part
15、3: Resistance to high differential pressure and to elevated temperature Part 4: Initial particle retention efficiency, life and cumulative efficiency (gravimetric method) Part 5: Method of test for cold start simulation and hydraulic pulse durability Part 6: Static burst pressure test Part 7: Vibrat
16、ion fatigue test Part 9: Inlet and outlet anti-drain valve tests Part 11: Self-cleaning filters Part 12: Filtration efficiency using particle counting, and contaminant retention capacity Part 13: Static burst pressure test for composite pressure vessel materials Part 15: Vibration fatigue test with

18、al integrity of full-flow lubricating oil filters to withstand engine vibrations. This test is intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min.This test method is intended for test parts made from materials that d
19、o not experience mechanical property changes within the temperature range experienced in service. The test may be applied to other filters if thought applicable by agreement between the filter manufacturer and the purchaser.2 Normative referenceThe following referenced documents are indispensable fo
