The flash point is one measure of the tendency of the sample to form a flammable mixture with air and is used to determine the overall flammability hazard of a material. Note: This procedure is only valid at the time of printing. The control version can be found on the Meraux Refinery intranet. Completed Date:Prepared By:Approved By: Flashpoint of Diesel by Pensky-Martens Closed Cup Tester 1Fill clean test crucible to the mark with sample ensuring that no wetting is present whatsoever above the mark. NOTE: Use attached picture as a reference for performing the following steps: 2Place crucible in heating block ensuring that the three round projections engage in the corresponding grooves in the crucible. 3Push locking arm to the right to latch crucible into heating block. 4 Place lid assembly onto test crucible such that the rectangular groove in the lid aligns with protrusion on test crucible and firmly closes. 5 Attach stirrer coupling, sample thermometer, flashpoint sensor and electrical igniter (if not already attached) to lid assembly as shown in diagram below. 6 Take the tie rod for the rotary slide out of the support on the holder for the storage pot and place onto the opening provided for it on the rotary slide. 7Inspect coil on electrical igniter – if dirty or crushed together, replace.

Completed Date:Prepared By:Approved By: Flashpoint of Diesel by Pensky-Martens Closed Cup Tester (continued) 8Press the Start key. 9 Enter sample ID in box that appears in the display – letters can be obtained by multiple pressing of appropriate number key; i.e. press #2 key three times to enter “6”. 10 After again pressing the Start key, the required measurement program can be selected using the arrow keys (#ASTM D93-A). 11Press Start button again to enter the expected flash point in ° F. 12Press Start again after EFP entered. 13Display prompts “Start Test?”, press Start. 14Once stirring begins, ensure that stirrer coupling is engaged. NOTE: On starting first the rotary slide on crucible lid is briefly opened for a zero-point adjustment. With a further insertion cycle a check is made whether the igniter and thermocouple are correctly positioned and inserted. 15 If an error occurs during the measurement, the test is cancelled and a continuous tone sounds – press the alarm switch-off button, a pop-up window emerges that gives a brief description of the error as well as the error number. 16 When the flashpoint has been determined successfully, an acoustic signal sounds which is silenced by pressing the alarm switch-off button. The result of the flashpoint is displayed. 17Record result from instrument display. 18Take test crucible out of heating block and place it in the storage pot for cooling. 19 Remove the stirrer coupling, flashpoint sensor and thermometer from lid of crucible and place in black holder provided on left side of the analyzer. 20Place tie rod in groove provided on left side of storage pot holder. 21Leave igniter attached to lid assembly as it tends to get damaged easily when moved. 22Once cooled, empty test crucible and rinse with toluene followed by acetone to clean.
