Conclusions:
The auto-ignition temperature was determined to be 255 °C under the test conditions.
Executive summary:

A study according to Regulation (EC) No. 440/2008 Method A.15 and DIN 51794 was conducted to determine the relative auto-ignition temperature of the test item. The auto-ignition temperature was determined using an automatic test system according to DIN 51794. It measures the lowest temperature at which auto-ignition occurs. The main test was performed in triplicate. The auto-ignition temperature is the lowest of the measured values rounded down to the nearest multiple of 5 °C. The auto-ignition temperature under the test conditions was determined to be 255 °C.

Description of key information

The auto-ignition temperature was determined to be 255 °C under the test conditions.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
255 °C
