A summary of the different main test is given below:

Main test series Auto-ignition temperature (°C) Time lag (s)
1st main test (5K) 398 5
1st main test (2K) 398 5
2nd main test (2K) 395 6
3rd main test (2K) 396 5
Conclusions:
The test item has an auto-ignition temperature of 390°C at atmospheric pressure.
Executive summary:

The auto-ignition temperature of the test substance was determined according to EU Method A.15. In a preliminary test the lowest auto-ignition temperature was found to be 402°C. This temperature was further refined in 4 main test series at which the temperature and amount of test item was varied. The lowest auto-ignition temperature that was observed was 395°C. Due to safety reasons and according to the guidelines the lowest measured temperature was round to the next lower number divisable by 5, giving an auto-ignition temperature of 390°C.

Description of key information

The self-ignition temperature of the test substance has been assessed according to EU Method A.15. The test item has an auto-ignition temperature of 390°C at atmospheric pressure.
