In the main test the lowest temperature where an ignition was observed was 83.0 °C.
The average measured flash point is corrected to the ambient pressure to be 83.195 °C
The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 83.0 °C.
Final Results
The test item has a flash point of 83.0 °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, CIPAC MT 12 (2009) and Guideline OCSPP 830.6315 (1996).
Description of key information
Flash point: 83.0 °C at 1005.1 hPa (EU Method A.9, closed cup)
Key value for chemical safety assessment
