No ignition was seen at 246 degrees C when tested at volumes of 400 to 1200 ul, and observed for 300 seconds, but greay fumes were emitted.

Conclusions:
The test item was determined to have an auto-ignition temperature of 248 +/- 5 degrees C. 
Executive summary:

The auto-ignition temperature was determined by heating aliquots of the test item in a flask, and observing for any ignition. Testing was conducted by a method designed to be compatible with Method A15 “Auto-ignition Temperature Liquids and Gases) of Commission Regulation (EC) No. 440/2008 of 30 May, 2008. The test item was determined to have an auto-ignition temperature of 248 +/- 5 degrees C.
