Conclusions:

The autoignition temperature of the test item was determined to be 410ºC at 996-1020 hPa.

Executive summary:

The auto-ignition assay for the test item was performed according to EU method A.15 (DIN 51794:2003-05). The test item was introduced in the ignition chamber (Erlenmeyer’s flask) and heated in a special apparatus. A preliminary test was performed to determine the initial temperature for the main determination. Then, the main determination was performed in five different stages to calculate the auto-ignition temperature. The auto-ignition temperature was determined to be 410ºC at 996-1020 hPa.
