Measure the temperature-- see 6.3.3 of the written standard-- of the fuel in the transfer container-- see 7.2 of the written standard-- and if necessary adjust to 15 to 25 degrees Celsius. Shake the sample or transfer container-- see 7.2 of the written standard-- vigorously for approximately 2 minutes. Rinse the fuel reservoir container-- see 6.1.5 of the written standard-- with some of the product to be tested. Place 450 plus or minus 5 milliliters of the sample into the fuel reservoir. See 6.1.5 of the written standard. Check that the temperature is still within the range from 15 to 25 degrees Celsius. Record the actual temperature. If any undissolved water is visually apparent in the fuel at this time, as determined by test methods D4176 or D4860 or both, the test shall be abandoned and the presence of water shall be reported. Place the end of the flexible inner tubing with the plastic coupler-- see 6.1.10 of the written standard-- into the collection container. See 6.1.6 of the written standard. Press and release the Purge push button. Approximately 40 milliliters will be drawn from the fuel reservoir through the flexible inner tubing and discharged into the collection container, thus purging the air and the residual fuel from the system. The fuel flow will automatically cease at the end of the purge cycle, 2 minutes. After the purge cycle, insert the plastic coupler affixed to the flexible inner tubing into a pre-calibrated Fcell filter-- see 6.2 of the written standard-- and place the filter into the mouth of the collection container. Press and release the Test push button. The peristaltic pump activates, drawing the fuel from the fuel reservoir and extruding it through the filter into the collection flask. During the filtration period, the pressure is constantly displayed along with the amount of sample processed. The test will automatically stop when one of the following occurs. The entire sample, 300 milliliters, is discharged prior to reaching 104 kilopascals, 15 pounds per square inch gauge. The total volume, V-- V equals 300 millimeters-- the final pressure P-- F-P less than 15 pounds per square inch gauge at 300 millimeters, and F-QF will be displayed. The entire sample, 300 millimeters, has not been discharged, and the maximum allowable pressure, 104 kilopascals-- 15 pounds per square inch gauge-- has been reached. The volume, V-- V at 15 pounds per square inch gauge-- discharged at 104 kilopascals, 15 pounds per square inch gauge. The final pressure P, F-P equals 15 pounds per square inch gauge. And the F-QF will be displayed. After completion of the test, prior to disconnecting the Fcell filter from the flexible inner tubing, release the lever on the pump to depressurize the system. Disconnect the Fcell filter from the flexible inner tubing and discard the unit. Insert the flexible inner tubing into the collection container-- 6.1.6 of the written standard-- and drain all of the residual fuel from the fuel reservoir container-- 6.1.5 of the written standard-- and flexible inner tubing, including the section connected to the pressure transducer.
