Applicant's summary and conclusion

Conclusions:
Auto-ignition temperature: 415°C.
Executive summary:

The auto ignition temperature was determined in three independent determinations. A lowest value of the main test of 415°C was found.

Therefore, the auto-ignition temperature according to EU A.15 (rounded down to a whole multiple of 5 °C) of the test item is stated as 415 °C.
