Applicant's summary and conclusion

Conclusions:
The lowest temperature giving a positive effect was 259°C. The injected volume was 200 microL, the ignition delay was 79 s. At a temperature of 254°C no ignition was observed.
Therefore, after rounding off to the next lower multiple of 5.0°C : Auto ignition temperature of ISORALDEINE 40 is 255°C +/- 5°C.
Executive summary:

The auto ignition temperature of ISORALDEINE 40 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 microL, the ignition delay was 79s. At a temperature of 254°C no ignition was observed.

Therefore, after rounding off to the next lower multiple of 5.0°C : Auto ignition temperature of ISORALDEINE 40 is 255 +/- 5°C.
