Applicant's summary and conclusion

Conclusions:
Auto-ignition temperature of the test item: 315±5°C
Executive summary:

The Auto-ignition temperature of the test item 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 319°C. The injected volume was 400 µl the ignition delay was 30 s. At a temperature of 314°C no ignition was oberved.

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

Auto-ignition temperature of the test item: 315±5°C
