In the pre-determination program a temperature of 300 °C was selected, which corresponds to an initial oven temperature of 200 °C. Using a constant heating rate, the subsequent ignition trials were conducted every 20 ± 5 K. Ignition occurs after 31 sec using 5 drops of test item at an oven temperature of 390.1 °C.

Conclusions:
The auto-ignition temperature of the test item 400112 according to EU A.15 was 345 °C.
Executive summary:

The auto-ignition temperature of 400112 was determined according to EU A.15.

An auto-ignition temperature of 349.6 °C was determined. This value is the lowest value in three independent determinations. This value was rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature was stated as 345 °C.
