- other: lowest auto-ignition temperature, rounded to lower number divisable by 5
- Conclusions:
- The test item was found to have an auto-ignition temperature of 215°C.
- Executive summary:
The auto-ignition temperature of the test item was assessed according to EU Method A. 15. In a preliminary test an indicative auto-ignition temperature of 227°C was observed. In the main test, 3 test series were performed. The lowest auto-ignition temperature that was observed was 220°C, this value was rounded off to 215°C.

The lowest auto-ignition temperature was found to be 220°C, due to safety reasons this was rounded to 215°C.
Description of key information
For this endpoint, one study is available in which the auto-ignition temperature was determined according to EU method A.15. The lowest auto-ignition temperature was found to be 215°C at atmospheric pressure (1011.1 hPa).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 215 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
