Applicant's summary and conclusion

Executive summary:

The lowest temperature giving a positive effect was 249oC. The injected volume was 100ul, the ignition delay was 52s. At a temperature of 244oC no ignition was observed.

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

Auto-ignition temperature of Cedrene Washed: 245 +/-10oC.
