In the main test the lowest temperature where an ignition was observed was 97.0 °C.

The average measured flash point is corrected to the ambient pressure to be 97.60 °C

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 97.5 °C.

 

Final Results

The test item has a flash point of 97.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2003).

Conclusions:
A flash point value of 97.5 °C (at 1009 hPa) was determined for the test substance according to E.U. Method A.9.
