Room temperature: 15 to 17 °C
Atmospheric pressure: 98.5 to 100.7 kPa
Observed result: 366 °C

Conclusions:
The test item has been determined to have an auto-ignition temperature of 366 ±5 °C.
Executive summary:

The Auto Ignition Temperature (Liquids and Gases) of the test substance was determined, using a procedure designed to be compatible with Method A.15 Auto-Ignition Temperature (Liquids and Gases) of Commission Regulation (EC) No 440/2008 of 30 May 2008. The result found was 366 ±5 °C.
