Atm. press.:

1 014 hPa

Preliminary test

The estimated auto-ignition temperature was 390°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 354°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 350°C.
