*The temperature was selected at the ZPA3 corresponding to an initial oven temperature of 200 °C. As the test item showed no ignition at 386.2 °C, a higher temperature was selected for the subsequent ignition trials corresponding to a new initial oven temperature of 400 °C. Using a constant heating rate, the subsequent ignition trials were conducted every 20 ± 5 K.

Conclusions:

The auto ignition temperature of the test item was determined to be 395 °C at 1013.25 hPa.

Executive summary:

A study was to determine the auto-ignition temperature of the test item according to Regulation (EC) No 440/2008 method A.15 and DIN 51794 Three independent determinations were conducted. The auto-ignition temperature was determined to be 395 °C 398 °C and 400°C respectively. According to the criteria as laid down in DIN 51794 the auto ignition temperature is the lowest value of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 395 °C. The three lowest values of the main study lay within a range of 20 K. No observations were made which might cause doubts concerning the validity of the study outcome. Thus, the validation criteria were fulfilled.
