Description of key information
EC 424-82-7 was found to have a auto-igntion temperature of 234 degrees centigrade.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 234 °C
Additional information
EC 424 -820-7 auto-ignition temperature was determined according to EEC 92/69 Method A15. Testing was conducted to a GLP standard.
A known volume of the registration substance was injected into a heated open Erlenmeyer flask containing air. The contents of the flask were observed in a darkened room for five minutes following injection of a sample or until ignition occurred. Ignition was evidenced by sudden appearance of a flame inside the flask. If the flame was not observed in 5 minutes the volume of sample tested was considered non-flammable at the temperature of the flask. If a flame was observed the timer was stopped and the time interval between sample injection and appearance of the flame recorded to the nearest second as the lag time. This was repeated at different temperatures and with different sample volumes until the minimum value of ignition temperature was obtained.
The registration substance was found to have a auto-ignition temperature of 234 degrees centigrade.
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.
