Description of key information

Autoignition temperature 250 ± 10 °C (EU method A15)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
240 °C

Additional information

The auto-ignition temperature of the test substance was determined according to guideline DIN 51794. At a temperature of 240

°C no ignition was observed. The lowest temperature giving a positive effect was 250 °C. Therefore, the auto-ignition temperature of the test substance was found to be 250 ± 10 °C. The +/- 10 °C refers to the reproducibility of the method as specified by the guideline.

According to the guidelines the lowest temperature giving a positive effect should be rounded down to the nearest multiple of 5 °C. However, since more temperatures in the range 240°C to 250°C were not tested a conservative value of 240°C has been chosen for

the purposes of the CSA even though no ignition was observed at 240°.
