This procedure will describe the determination of the flash point (the lowest
temperature of a liquid at which application of a flame causes the vpor
above the liquid to ignite) of process samples. A test cup is filled to a
marked level and the sample is heated at a constant rate with continual
stirring. An electric igniter is dipped into the cup at regular intervals with
simultaneous interruption of stirring until ignition is detected by the analyzer.
The temperature at which ignition occurs is recorded and displayed as the
flashpoint measurement.

Flashpoint by Pensky-Martens using Herzog MP 329
1
Switch on the instrument by pressing green power toggle located right front of analyzer.
2
Press “Start” key – if the display shows the last test result press the “Start” key again.
3
Select “ASTM-A” method using the “P” key for samples where the expected flashpoint is known.
a. Select program “5” if the sample flashpoint is unknown.
NOTE: The display will show input area for sample identification. A flashing cursor indicates that new information can be entered.
4
Enter sample ID:
a. Select letters by scrolling with the ↑ and ↓ arrow keys.
b. Move cursor position using the → and ← arrow keys (character is deleted if ← is pressed).
c. Numbers are entered directly using keypad.
d. Up to fourteen characters may be entered.
5
Once sample ID is entered, press “Start” key.
6
Enter the expected flashpoint (EFP) using keypad (temperature value range is +10 - +370°C).
a. If the expected flashpoint is unknown i.e. program “5” was selected, use → key to indicate a pretest will be required.
7
Fill test cup to the mark ensuring that no wetting occurs above mark inside the cup.
8
Inspect condition of coil on electrical igniter – if dirty or crushed together, replace.
9
Place cup in heating block so that the 3 circular keys fit into corresponding slots and lock with the white knobbed locking arm.

10
Place the cover on the test cup so that the rectangular key fits into the cover slot and is fully engaged.
11
Place stirrer coupling, igniter system arm, thermometer and flash detector pin in appropriate positions on test cup lid (refer to diagram
on following page).
12
Press “Start” key – barometric pressure will be displayed.
13
Press “Start” key – the question “Start Test?” will be displayed.
14
Press “Start” key again.
NOTE: Once test is started, a pre-warming phase begins for sample. Several trial checks are also performed by the analyzer before
actual testing begins.
15
Once testing is completed, an acoustic signal will indicate flash point detection; press the “Stop” key to acknowledge.
16
Record the flashpoint reading from the display.
17
Take cup out of heating block and place in storage cup for faster cooling.
18
An acoustic signal will indicate end of sample cooling phase – press “Stop” key to acknowledge.
19
Discard spent sample into oily waste container.
20
Clean sample cup with toluene followed by acetone.
21
Place stirrer coupling, igniter system arm, thermometer and flash detector pin in appropriate storage compartments.
