Reference
Preliminary test:
The estimated auto-ignition temperature was 350 °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 table below.
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 344 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test substance of 340 °C.
