Key result
Auto-ignition temperature:
415 °C
Atm. press.:
1 009 hPa

 Preliminary Test

The estimated auto-ignition temperature was 420°C.

Main Study

The results of the main study on the determination of the auto-ignition temperature of the test item are given inTable 8.

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 418°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 415°C.
