Reference
Preliminary test:
The estimated auto-ignition temperature was 405 °C.
Main study:
The results of the main study on the determination of the auto-ignition temperature of the test substance are given in the below table. Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20 °C. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test substance occurred was 403 °C. This temperature was rounded off to the nearest multiple of 5 °C giving an auto-ignition temperature of the test substance of 400 °C.
