Applicant's summary and conclusion

Conclusions:
The Auto-ignition Temperature of Irone Alpha was determined in a SUR BERLIN oven, equipped with a 250 ml glass ignition vessel according to the DIN 51794.

The lowest temperature giving a positive effect was 259°C. The injected volume was 200 µl, the ignition delay was 20 s. At a temperature of 254°C no ignition was observed.

Therefore, after rounding-off to the next-lower multiple of 5°C:

Auto-Ignition temperature of Irone Alpha: 255 ± 10°C
