Applicant's summary and conclusion

Conclusions:
Results:
An exothermic reaction of the test substance occurs at a temperature of 155°C and leads to approx. 207°C. A second exothermic reaction begins at 270°C and leads to a temperature of 334°C. After this the temperature of the test substance was permanent over the oven temperature until the maximum temperature of 420°C.
Final result:
The relative self-ignition temperature is 383°C
Executive summary:

The relative self-ignition temperature is 383°C
