According to DIN EN 13463 -1 the test item has to be assigned to temperature class 2 according to DIN EN 13463 -1. The auto-ignition temperature for liquids is not directly used for classification and labelling according to regulation (EC) 1272/2008, but can be used in the chemical safety assessment in considering risks associated with processing the substance. (ECHA Guidance on information requirements and chemical assessment , chapter R7A: endpoint specific guidance, May 208)

Conclusions:
The test item has an auto-ignition temperature of 410 °C.
Executive summary:

The test item has an auto-ignition temperature of 410 °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.
