Key result
Auto-ignition temperature:
ca. 643 K

Any other information on results incl. tables

Preliminary test

The estimated auto-ignition temperature was 380°C.

Main study

The results of the main study on the determination of the auto-ignition temperature of the test item are given inTable 6.

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 371°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 370°C.
