Key result

Auto-ignition temperature:

270 °C

Atm. press.:

1 023.3 - 1 035 hPa

Remarks on result:

other: The lowest temperature at which ignition of the test substance occurred was 272°C. This temperature was rounded off to the nearest multiple of 5°C.

Preliminary result:

The estimated auto-ignition temperature was 300°C.

Main study result:

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 <10°C. According to the guidelines, no further testing was required.

 

The lowest temperature at which ignition of the test substance occurred was 272°C. This temperature was rounded off to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 270°C.
