Reference
Preliminary test
Table 1 displays the results, an ignition is denoted as “+” and no ignition is denoted as “-“. At each temperature, 5 drops were put into the Erlenmeyer flask.The atmospheric pressure was 1005.9 hPa.

The lowest auto-ignition temperature was 304 °C.
Conclusion: 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, the test item has an auto-ignition temperature of 300 °C. According to DIN EN 14522, it has an auto-ignition temperature of 299 °C.
The auto-ignition temperature for liquids is not used directly for classification and labelling according to Regulation (EC) 1272/2008. It can however be used in the chemical safety assessment in considering risks linked with processing the substance. According to DIN EN 13463-1 the test item has to be assigned to the temperature class T3 (see Table 3).
