- Key result
- Auto-ignition temperature:
- 395 °C
- Atm. press.:
- > 1 006.7 - < 1 019.2 hPa
- Remarks on result:
- other: The lowest temperature at which ignition of the test substance occurred was 398°C. This temperature was rounded down to the nearest multiple of 5°C giving the auto-ignition temperature of the test substance.
- Conclusions:
- The auto-ignition temperature of the substance was determined to be 395°C at 1006.7 -1019.2 hPa using a commercially available auto-ignition temperature apparatus (in accordance with EC A.15, DIN 51794 and IEC 79-4 and in compliance with GLP).

Description of key information
The auto-ignition temperature of the substance
was determined to be 395°C at 1006.7 -1019.2 hPa
using a commercially available auto-ignition
temperature apparatus (in accordance
with EC A.15, DIN 51794 and IEC 79-4
and in compliance with GLP).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 395 °C
Additional information
Because the auto-ignition temperature of the test substance, at 101325 Pa, has been determined to be 395 °C, the test substance is not to be classified for self-heating substances and mixtures, according to the CLP regulation.
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.
