In the main test the lowest temperature where an ignition was observed was 84.0 °C.

The average measured flash point is corrected to the ambient pressure to be 84.825 °C

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 84.5 °C.

 

Final results

The test item has a flash point of 84.5 °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, CIPAC MT 12 (2009) and Guideline OCSPP 830.6315 (1996).  

Conclusions:
A flash point value of 84.5 °C (at 1000 hPa) was determined for the test substance according to E.U. Method A.9.

Description of key information

Flash point: 84.5 °C at 1000 hPa (EU Method A.9, Pensky-Martens, non-equilibrium, closed cup method)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
84.5 °C
