Interpretation of results:
GHS criteria not met
Conclusions:
A flash point of 195.5 ± 0.7 °C at 1013.25 hPa was determined for the test item using a non-equilibrium method (Pensky-Martens apparatus).
Executive summary:

A study was conducted according to EU-Method A.9 as of 31 July 1992 to determine the flash point of the test item using a non-equilibrium method. About 70 mL of the liquid test item were brought into the clean test vessel. Then the test vessel was set into the instrument and the instrument was started. The pre-test was performed with a heating rate of 8.5 K/min and the main test with a heating rate of 5.5 K/min. The flash point is given as the mean value of the two corresponding determinations (deviation smaller than 2 K). The measured flash point is therefore 195.5 ± 0.7 °C.
