Remarks:
The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 280 °C.

The auto-ignition temperature rounded down to the nearest multiple of 5°C was determined as 280°C, according to Regulation EC No. 440/2008 and DIN 51794. According to DIN EN 14522, the auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 278°C.

Conclusions:
The auto-ignition temperature of the test item was determined to be 280°C (2018)
Executive summary:

The auto-ignition study was conducted in accordance with EU Method A.15 (Auto-ignition Temperature (Liquids and Gases)) and is therefore considered reliable without restrictions (Klimisch 1). A preliminary test and three main tests were carried out to determine the auto-ignition temperature of the test item. In conclusion, the test item has an auto-ignition temperature of 280 °C according to the Regulation EC No.440/2008 Method A.15 Auto-ignition temperature (liquids and gases).

According to DIN EN 13463-1 the test item has been assigned to temperature class T3 (maximum surface temperature / minimum auto-ignition temperature 200 °C).
