This SAE Standard is intended for all sizes of fuel filters, so a variety of test stands may be required depending upon flow rate. The low contamination level, downstream clean-up filter, and short duration of the test, ensures that the particle retention ability of the filter is measured in a single pass as no appreciable loading or regression will occur. The rationale for revising J1985 is twofold. First it was up for the standard five year review. The second reason is to take advantage of advances in technology and other updated documents. The technology of on-line optical particle counting has been substantiated in ISO 11943: 1999. Advances in technology of characterizing the performance and calibration of optical particle counters has been addressed with the new ISO 11171: 1999. Lastly two documents which define materials used for testing: ISO 12103-1 Test Dusts and SAE J1696 Standard Fuel Filter Test Fluid.
