Key result

Flash point:

103.5 °C

Atm. press.:

1 013 hPa

Preliminary test

Amount of test item / g	Temperature / °C	Ignition (+/-)	Air pressure / hPa
67.94	107.0	+	1020.9

In the preliminary test the lowest temperature where an ignition was observed was 107.0 °C.

Main test

Amount of test item / g	Temperature / °C	Ignition / (+/-)	Air pressure / hPa	Corrected flash point / °C
67.24	104.0	+	1021.9	103.8
66.81	104.3	+	1022.3	104.1

The measured flash points are corrected to the ambient pressure and averaged to be 103.95 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 103.5 °C.

Interpretation of results:

GHS criteria not met

Conclusions:

The flash-point of the test item was determined to be 103.5 °C.

Executive summary:

A study was conducted according to Regulation EC No. 440/2008 Method A.9. Flash Point andDIN EN ISO 2719 (2016)to determine the flash point of the test item using non-equilibrium closed cup method. A Pensky-Mertens apparatus was used for this purpose. The approximate flash point was determined in a preliminary test. The first ignition trial of the main test is performed at a test item temperature 23 ± 5 °C below the approximate flash point determined in the preliminary test. The flame is dipped in the cup at 1 K intervals. The main test was performed twice. The mean flash point corrected to standard pressure of 1013 hPa and rounded down to the nearest multiple of 0.5 °C was determined to be 103.5 °C.
