5、istries that have taken place in the industry since the previous revision in 1999. 1. SCOPE The purpose of this fuel filter test method is to provide standardized methods for evaluating the performance characteristics of fuel filters by bench test methods. This, combined with data obtained from appl
6、ication tests, may be used to establish standards of performance for filters when tested by these standard methods. Many variations in requirements of filtration to protect fuel supply equipment on engines and variations in operating conditions make it difficult to specify meaningful “in-service“ pe
7、rformance standards by which a filter may be judged. By the use of these standard test methods, test conditions are always the same, and comparisons of the laboratory performance of filters may be made with a high degree of confidence. Once the requirements of a particular application are known, per
8、formance standards for suitable filters may be established by these test methods, and adequacy of performance of filters for the job may be determined. In order to achieve the highest degree of reliability of test results, the procedures and equipment must conform to those specified in this code. No
9、 minimum performance requirements for filters have been specified, since these are the responsibility of the user and manufacturer. Only the methods of determining, interpreting, and reporting performance characteristics are the proper province of this SAE Standard. Separate chapters cover the test
10、methods necessary to evaluate the several functional capabilities and mechanical properties of the filter. Each chapter is complete with recommended materials, apparatus, and procedures for testing and evaluation. The chapters are: a. Chapter 1Resistance to Flow (Section 3) b. Chapter 2Filter Capaci

CHAPTER 1RESISTANCE TO FLOW 3.1 Scope The resistance to flow test determines the pressure loss, which will result when standard test fluid is passed through the filter under standard conditions of flow and f
22、luid viscosity. This procedure may be used to establish flow capacities, and is the method for measuring resistance to flow of sample filters against an established performance standard. 3.2 Test Materials 3.2.1 Test Fluid SAE J1696 Standard Fuel Filter Test Fluid. 3.3 Test Apparatus 3.3.1 Fuel filt
23、er flow test stand (or equivalent). A pump, flowmeter, thermometer, and manometers or differential pressure gauge are necessary as shown in Figure 1. It is usually convenient to use the fuel filter test stand as described in 4.4.1. SAE J905 Revised SEP2009 Page 4 of 34FIGURE 1 - FLOW TEST STAND 3.3.
24、2 Filter housing or mounting plate with pressure taps located to give pressure loss across the filter element (or across the entire filter unit, in the case of “spin-on“ and “in-line“ filters). See Figures 2 and 3 for housing and mounting plate details. 3.3.3 If special housings are necessary or des
25、irable, care must be exercised to locate inlet and outlet pressure taps to obtain true pressure values.

27、uid through a cleanup filter until the test fluid cleanliness is less than 2 mg/L (see Appendix A for methods for sample analysis). Remove the cleanup filter and install the test filter. 3.5 Test Procedure 3.5.1 Circulate the test fluid through the test filter and adjust flow rate to 20% of the flow
28、 rate specified for the Capacity and Contaminant Removal test, at the specified test temperature. When the temperature and flow rate have stabilized, record the pressure differential. Adjust the flow rate in increments of 20% of the specified test flow rate, to a maximum of 120%, and record pressure
29、 differential after stabilization at each increment. 3.5.2 If the filter housing does not have pressure taps located to read element pressure only, an empty housing pressure differential must be obtained. The difference between the pressure loss for the empty housing and for the housing with element
30、s is the pressure loss for the element only. For “spin-on“ and “in-line“ filters, pressure loss for the complete unit may be the only value of interest, in which case pressure loss for the element only will not be required. 3.6 Presentation of Data 3.6.1 Tabulate pressure differential at each requir
31、ed flow and temperature. 3.6.2 Plot a curve of flow rate versus pressure differential using the ordinate for pressure differential and the abscissa for flow rate. 4. CHAPTER 2FILTER CAPACITY AND CONTAMINANT REMOVAL CHARACTERISTICS 4.1 General Information This procedure has been developed to provide
32、a standard method for evaluating filter performance in terms of contaminant holding capacity and ability to maintain effluent cleanliness within specified contamination limits. These characteristics are defined as follows: 4.1.1 Contaminant Holding Capacity The amount of abrasive contaminant removed
33、 from a recirculating flow of test fluid and held by the filter before a specified pressure drop across the filter is reached. The limiting pressure drop is specified by the user and is related to the limitations of the fuel system served by the filter. 4.1.2 Fluid Cleanliness The measure of the lev
34、el of contaminant remaining in the filter effluent fluid samples at specified time intervals during the test with abrasive contaminant. Cleanliness is specified in terms of mass of contaminant per unit volume of fluid, or mass of contaminant per unit mass of fluid.Test fluids and contaminants have b
35、een selected because their characteristics are closely controlled so that, used in accordance with standard procedures contained in this document, test results will be repeatable and comparable among laboratories using these test procedures. Producers of the test materials will not alter any charact
36、eristics unless they have first ascertained that the proposed change will have negligible effect on all tests in which they are used. No changes are made without consultation with the SAE Filter Test Methods Committee. SAE J905 Revised SEP2009 Page 8 of 344.1.3 Cautionary Notes Prior standard tests
37、incorporated in SAE J905 used a nondispersant fluid for the tests of filtration efficiency and dirt capacity. The test fluid specified for the tests in this chapter has significant dispersancy. For this reason, apparent filtration efficiency and capacity by this revision will be significantly lower
38、than if the same filter was evaluated by the older method. These results are more realistic than earlier test results and are more repeatable and reliable. This test is an evolution of the previously used test, which was derived from years of experience in the testing of fuel filters. However, the p
39、rocedure is limited strictly to the laboratory comparison of filters. Test results are not directly relatable to the field performance of the filter. The differences between laboratory results and field experience are attributable to the types of contaminant used in the test procedure and that found
40、 in the field. General experience is that fuel filters in the field become restricted rapidly dueto asphaltenic type materials in the fuel. Asphaltenic materials are micron or submicron particles of carbon with a resinous coating. The abrasive contaminant used in this test procedure provides a poor
41、approximation of this type of clogging action. This is supported by the experience that plugged field filters have only a small fraction of the contaminant weight gain as one would expect from this test procedure. The SAE Filter Test Methods Committee has ongoing programs to evaluate new test method
42、s for the investigation of fuel filter capacity and efficiency. These programs address the contaminant problem and the relation of test results to field performance. In addition, testing avenues such as particle counting are being used for fuel filtration evaluation. Consideration will be given to n
43、ew technology and testing methods, as they become known to the FTMC. This test procedure has been included in the interim because there are years of background and data, which have been generated through its use. Most users have significant experience with the procedure and have developed special in
44、-house methods to extend the test results to field applications. Although this is not the optimal situation, the FTMC feels that this procedure will be useful in the interim, as long as users continue to exercise care in the interpretation of the testresults. Test results using ultrasonically disper
45、sed test dust show slightly lower efficiency and dirt capacity than when the Waring blender is used. The differences in results between these two methods are within the normal expected variation among laboratories. The Waring blender is specified because it will reliably disperse the test dust adequ
46、ately. Other blenders have been tried, and results show that the dust was not well dispersed. Blenders, which can be demonstrated to disperse contaminant as well as the Waring, verified by test results, which correlate well with test results using a Waring blender, may be used. The Committee has no
47、evidence to recommend other blenders, but some may be available. 4.2 Scope This test determines the abrasive contaminant holding capacity and abrasive contaminant removal characteristics of fuel filters. While the test is generally applied to filters intended to handle fuel oils for diesel engines,
48、it is equally applicable to filters for other classes of liquid fuel. The specified test fluid has viscosity characteristics similar to No. 2 diesel fuel.In the construction of the test stand, care must be taken to insure that any contaminant added to the test sump is properly dispersed and fully pr
49、esented to the test filter. To insure validation, the system must not have any traps or settling zones where contaminant could be lost, nor should the pumping system alter the contaminant in any way. The test apparatus recommendations are made with these points in mind. 4.3 Test Materials 4.3.1 Test Fluid SAE J1696 Standard Fuel Filter Test Fluid. 4.3.2 Test Contaminant ISO 12103-1, A2 Fine Grade.
