Key result

Auto-ignition temperature:

394 °C

Atm. press.:

>= 99.9 - <= 100.2 kPa

The auto-ignition temperature was 394 ± 7°C, with a 500 µL sample volume. The testing was carried out over two days, the atmospheric pressure at the time of testing was 99.9 kPa on first day and 100.2 kPa on second day. The full results are shown in the following table:
