Key result
Auto-ignition temperature:
455 °C
Atm. press.:
>= 1 018.2 - <= 1 027.3 hPa

Ignition of the 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 substance occurred was 458°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the substance of 455°C.

Conclusions:
The substance is auto-ignitable with an auto-ignition temperature of 455°C at 1018.2 –1027.3 hPa.
Executive summary:

The substance is auto-ignitable with an auto-ignition temperature of 455°C at 1018.2 –1027.3 hPa.
