The Pensky-Martens closed cup flash point test
Detailed Results for Solvent-free Dabco TMR
Test Date: 08/18/2016
Relative Humidity: 59; 59%
Room Temperature: 23.0; 23.1°C
Barometric Pressure: 992; 992 mbar
Observed Flash Point Temperature
Corrected Flash Point Temperature
The Pensky-Martens tester, a closed cup apparatus, was used to determine
the flash point of the material. Prior to testing, the sample cup and
lid were inspected for cleanliness and any contaminants were removed.
The barometric pressure, room temperature, and relative humidity were
then recorded. The test sample was added to the sample container to the
filling mark inside the test cup. The heating dial was turned on and
adjusted to the desired heating level. The switch for the stirrer was
turned on, mixing the vapor space and the bulk liquid. The heating rate
for the test was approximately 5 to 6°C per minute. The valve was opened
on the methane tank and the pilot flame was lit. The test flame was then
adjusted to match the 4mm diameter gauge ring on the lid by turning the
pinch valve. The test flame was applied to the sample every 1°C. While
the test flame was applied, the stirring motor was turned off.
Visual observations were made and the flash point temperature was
recorded. The sample is deemed to have flashed when a large flame
appears and instantaneously propagates itself over the entire surface of
the test specimen. Once the observation was recorded, the valve on the
apparatus for the gas line was closed to extinguish the flame.
FP = T + 0.033(760 - P)
T = Observed flash point temperature (°C)
P = Barrometric pressure (mm Hg)
The actual flash point of the sample was then reported as the corrected
temperature. The corrected temperature is rounded to the nearest 0.5°C.
After the sample flashed or boiling was observed, the test was
terminated. The sample was allowed to cool near room temperature, the
sample was then discarded and the tester was thoroughly cleaned. The
flash point temperature was then corrected using the following equation.
Hydroxypropyl, N-2-, N,N,N-trimethylammonium 2-ethylhexanoate flash
point was determined to be 134.5 C by Pensky-Martens closed-cup test.
