The measured flash points are corrected to the ambient pressure and averaged to be 150.0 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 149.5 °C

Conclusions:
The flash point of the test substance has been determined to be 149.5 °C at 1013.1 hPa atmospheric pressure.
Executive summary:

The flash point was determined using EU Method A.9 closed cup equilibrium method. In the main test the lowest temperature where an ignition was observed was 150.0 °C at 1013.1 hPa, which was then corrected to the ambient pressure to be 150.0 °C. The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 149.5 °C. The flash point of the substance has been determined to be 149.5 °C at 1013.1 hPa atmospheric pressure.

Additional information

The flash point was determined using EU Method A.9 closed cup equilibrium method. In the main test the lowest temperature where an ignition was observed was 150.0 °C at 1013.1 hPa, which was then corrected to the ambient pressure to be 150.0 °C. The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 149.5 °C. The flash point of the substance has been determined to be 149.5 °C at 1013.1 hPa atmospheric pressure.
