In the main test the lowest temperature where an ignition was observed was 56.5 °C.

The mean measured flash point is corrected to the ambient pressure to be 56.62 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 56.5 °C.

 

 

Final Results

The test item has a flash point of 56.5 °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, DIN EN ISO 13736 (2013).

Conclusions:
A flash point value of 56.5 °C (at 1013 hPa) was determined for the test substance according to E.U. Method A.9.
