Conclusions:
Auto-ignition temperature of the test item was determined to be 170 °C at 1013.25 hPa.
Executive summary:

Auto-ignition temperature of the test item was determined in three test series according to EU method A.15 and DIN 51794:2003 -05. The auto ignition temperature is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. The three lowest values of the main study lay within a range of 10 K as required for auto ignition temperatures below 300 °C. Thus, the validity criterion which is demanded in the DIN standard was fulfilled. Auto-ignition temperature of the test item was determined to be 170 °C at 1013.25 hPa.
