It has
16、been prepared in separate parts, each part relating to a particular performance characteristic. Together the tests provide the information necessary to assess the characteristics of a filter, but if agreed between the purchaser and the manufacturer, the tests may be conducted separately. 1 Scope and
17、 field of application This part of ISO 4548 specifies a method of testing full-flow lubricating oil filters for internal combustion engines to determine their ability to withstand a static pressure objective and to determine their burst pressure and the failure mode concerned. It does not apply to f
18、ilters for use in aeronautical applications. 2 Reference ISO 4548-1, Methods of test for full-flow lubricating oil filters for internal combustion engines Part 1: Pressure drop/flow characteristics. 3 Definitions For the purposes of this part of ISO 4548, the definitions given in part 1 apply. 4 Tes
19、t rig Hydraulic hand pump with high-pressure tubing and valves, pressure gauge with measuring range of 0 to 30 bar2), or higher if the specified pressure objective (see 6.6) requires it, adaptor to attach the complete filter. A transparent safety shield shall be used. 5 Test liquid SAE 5 W oil at am
20、bient temperature shall be used. 6 Preparation and test procedure 6.1 Assemble the complete filter using the recommended tightening torque. If a tolerance is given, apply the minimum tightening torque. The filter to adaptor connection shall be equivalent to the production mounting conditions. 6.2 Co
21、nnect 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. 6.3 Introduce oil into the system by operating the pump until oil is seen to emerge from the outlet of the valve. This in
22、dicates that all the air has been excluded from the system. 6.4 Close the valve and position the safety shield between observer and filter. 6.5 Raise the pressure gradually to 2 bar, maintain for about 1 min, and check the filter and all fittings for leaks. 6.6 Now raise the pressure gradually in in
23、crements of about 2 bar, maintain for about 1 min at each increment, and check the filter for leaks or distortion. Continue until a specified pressure objective is reached (or otherwise a failure occurs). 6.7 Relieve the pressure to zero. Check the filter for permanent distortion and tightening torq
24、ue. Note the remaining tightening torque and if loosening has occurred, restore the initial value. 6.8 Gradually apply pressure again until the previous pressure is reached, then proceed gradually in increments of about 0,5 bar and maintain for about 10 s at each increment. Continue until ultimate f
25、ailure occurs, i.e. bursting or leaking. 6.9 Examine the filter for details of the failure mode. 7 Report of test results The test report shall indicate at least the following: a) a reference to this part of ISO 4548; b) test establishment; c) filter type (manufacturer model No. and batch No.); d) d
26、ate 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); g) the specified pressure objective and whether reached (see 6.6); h) the remaining tightening torque (see 6.7); j) visible permanent
27、 distortion (see 6.7); k) the burst pressure (see 6.8); m) the mode of failure and its location. 2) 1 bar = 100 kPa Licensed Copy: London South Bank University, London South Bank University, Fri Dec 08 11:48:38 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 2 blank Licensed Copy: London South Bank Unive
