Key result

Auto-ignition temperature:

220 °C

Atm. press.:

>= 1 021.4 - <= 1 028.1 hPa

Prelim Test

The estimated auto-ignition temperature was 245 °C.

Main Test

Ignition of the test item 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 item occurred was 224 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test item of 220 °C.
