In the main test the lowest temperature where an ignition was observed was 115.0 °C.


The measured flash point is corrected to the ambient pressure to be 115.6 °C


The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 115.5 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
A flash point value of 115.5°C (at 1013 hPa) was determined for the test substance according to E.U. Method A.9.
Executive summary:

Determination of the flash point was conducted using the Pensky-MArtens method. A flash point value of 115.5°C (at 1013 hPa) was determined.

In the main test the lowest temperature where an ignition was observed was 136.0 °C.

The average measured flash point is corrected to the ambient pressure to be 136.223 °C

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 136.0 °C.

Final results

The test item has a flash point of 136.0 °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).

 

 

Conclusions:
A flash point value of 136 °C (at 1013 hPa) was determined for the test substance according to E.U. Method A.9.
