Applicant's summary and conclusion

Conclusions:
The lowest temparture giving a positive effect was 249°C. The injected volume was 200 microL, the ignition delay was 54s. At a temperature of 248°C no ignition was observed.
Therefore, after rounding off to the next lower multiple of 5°C: Auto-ignition of VELVIONE: 245 +/- 10°C.
Executive summary:

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

The lowest temparture giving a positive effect was 249°C. The injected volume was 200 microL, the ignition delay was 54s. At a temperature of 248°C no ignition was observed.

Therefore, after rounding off to the next lower multiple of 5°C: Auto-ignition of VELVIONE: 245 +/- 10°C.
