Applicant's summary and conclusion

Conclusions:
The lowest temperature giving a positive effect was 244°C. The injected volume was 100 microliters, the ignition delay was 19 s. At the temperature of 239°C no ignition was observed.
Therefore, after rounding-off to the next lower multiple of 5°C:
Auto-ignition temperature of Bisabolene: 240 +/- 10°C.
Executive summary:

The auto-ignition temperature of Bisabolene was determined in a SUR BERLIN oven, equipped with a 250ml glass ignition vessel according to the DIN 51794.

The lowest temperature giving a positive effect was 244oC. The injected volume was 100ul, the ignition delay was 19s. At a temperature of 239oC no ignition was observed.

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

Auto-ignition temperature of Bisabolene: 240 +/- 10oC.
