Based on results of the main test series, the lowest auto-ignition temperature was 396 °C.

Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 395 °C.

 

Final Results

The test item has an auto-ignition temperature of 395 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.

Conclusions:
An auto-ignition temperature value of 395 °C (at 1015.7 hPa) was determined for the test item according to E.U. Method A.15.
