Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Autoignition temperature 300 ± 10 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 290 °C
Additional information
The auto-ignition temperature of the test substance was determined according to guideline DIN 51794. At a temperature of 290
°C no ignition was observed. The lowest temperature giving a positive effect was 300°C (injection volume 100µL, ignition delay 9seconds). Therefore, the auto-ignition temperature of the test substance was found to be 300 ± 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 290°C to 300°C were not tested a conservative value of 290°C has been chosen for the purposes of the CSA even though no ignition was observed at 430°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
