Conclusions:
The auto-ignition temperature of the test item was determined to be 230 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A.15 and DIN 51794 (2003) to determine the auto-ignition temperature of the test substance. In a preliminary test the approximate auto-ignition temperature was determined. For the main test four test series were conducted. The temperature determined in the preliminary test was used as starting point for the main test. According to criteria laid down in Regulation EC No. 440/2008 method A.15 and DIN 51794 the auto-ignition temperature is the lowest value rounded down to a whole multiple of 5 °C. Therefore, the auto-ignition temperature was determined to be 230 °C at atmospheric pressure.

Description of key information
