19、)IntroductionISO 4548 (all parts) establishes standard test procedures for measuring the performance of full-flow lubricating oil filters for internal combustion engines. The series has been prepared in separate parts, each part relating to a particular performance characteristic.Together the tests
20、provide the information necessary to assess the characteristics of a filter, but if agreed between the purchaser and the manufacturer, the tests can be conducted separately. This part of ISO 4548 deals with filter modules made of composite materials for internal combustion engines in terms of static
21、 burst pressure.

22、flow lubricating oil filters for internal combustion engines to determine their ability to withstand a static pressure objective at high and cold temperatures and to determine their burst pressure and the failure mode.It applies to all oil filters, for example spin-on ones and filters made of temper
23、ature sensitive materials.It applies to new filters and filters returned from endurance tests.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 4548-1, Methods of test for full-flow lubricating oil filters for internal combustion engines Part 1: Differential pressure/flow characteristics3 Terms and definitionsFor the purposes of t
25、his document, the terms and definitions given in ISO 4548-1 apply.4 Test rigThe test rig shall include a hydraulic hand pump or other appropriate technology to generate the required pressure, with high pressure tubing and valves, a pressure device located downstream to the filter under test with mea
26、suring range of 0 kPa to 3 000 kPa or higher if the specified pressure objective see 6.1 g) requires it, and an adaptor to attach the complete filter.To allow tests at a temperature between 30 C and +150 C, an environmental chamber is recommended.The filter samples will be tested by default at a tem
27、perature between 30 C and +150 C.A means of recording pressure or detecting the maximum reached pressure shall be supplied in order to allow the continuous follow up of the pressure and to detect the pressure at which the leak occurs.The test rig shall be designed such that operators can conduct the
28、 test safely.INTERNATIONAL STANDARD ISO 4548-13:2013(E) ISO 2013 All rights reserved 1BS ISO 4548-13:2013ISO 4548-13:2013(E)16735248Key1 oil sump 7 climatic chamber2 Pump 8 temperature sensor3 pressure sensor M motor4 filter under test T temperature5 closing valve P pressure6 pressure regulating val

30、 be functional between 30 C and +150 C (or the temperature range agreed by the manufacturer and the purchaser) to avoid its inflammation or its gelling. The viscosity of the oil shall be between 5 mm2/s and 10 000 mm2/s in the temperature range.6 Preparation and test procedure6.1 Verification that f
31、ilters meet technical requirementsa) Assemble the complete filter using the recommended tightening torques (relative to the cover, the spin-on samples, etc.). If a tolerance is given, apply the minimum tightening torque. The filter to adaptor connection shall be equivalent to the one on the engine,
32、as agreed between manufacturer and customer.b) Connect the pump to the inlet of the filter or adaptor, and the outlet of the filter or adaptor to an open valve. The outlet of the valve should be the highest point of the system.2 ISO 2013 All rights reservedBS ISO 4548-13:2013ISO 4548-13:2013(E)c) In
33、troduce oil into the system by operating the pump until oil is seen to emerge from the outlet of the valve. This indicates that all the air has been excluded from the system.d) Close the valve and position the safety shield between observer and filter.e) Set the fluid temperature in order to have th
34、e filter sample temperature at the specified one and then cool or heat the sample (if possible, put the temperature sensor inside the housing or at its surface).f) As soon as the specified test temperature has been reached and maintained during at least 1 h, raise the pressure gradually to 200 kPa,
35、maintain for more than 1 min, and check the filter and all fittings for leaks.NOTE If appropriate burst pressure is known, the first pressure increment can be 50 % of the known value. This shortens the test time for high-pressure filters without a loss in data quality.g) Raise the pressure at a cont
36、rolled pressure ramp up to approximately 100 kPa per 10 s, maintain for more than 1 min at each increment, and check the filter for leaks. Continue until the specified pressure is reached and maintain for 1 min (unless a failure occurs).h) Relieve the pressure to 0 kPa. Allow the fluid and environme
37、ntal chamber temperatures to return to ambient conditions and then measure the remaining tightening torque relative to the cover and the spin-on cartridge. Then unscrew the filter or cap and identify any kind of permanent distortion.6.2 Determination of the filter failing pressurea) Apply 6.1 a) to
38、6.1 f) with another filter.NOTE If appropriate burst pressure is known, the first pressure increment can be 50 % of the known value. This shortens the test time for high-pressure filters without a loss in data quality.b) Continue to increase pressure gradually in increments of about 100 kPa for 10 s
39、. Maintain for about 10 s at each increment until failure occurs, i.e. bursting or leaking.c) Examine the filter for details of the failure mode.7 Test reportThe test report shall indicate at least the following:a) a reference to this part of ISO 4548 (i.e. ISO 4548-13);b) the test establishment;c)
40、the filter type (manufacturer model no. and batch no.);d) the date of test;e) a description of the filter, whether it is new or used (in the latter case, approximate period of service);f) the torque applied initially see 6.1 a);g) the test temperature;h) the oil viscosity;i) the specified pressure o
