Description of key information
For 1,1,1,2 -tetrafluoroethane (HFC 134a) auto-ignition temperature was found to be in excess of 743°C (1016K) at 1 atm pressure.
Key value for chemical safety assessment
Additional information
The degree of auto-ignitabality is expressed in terms of the auto-ignition temperature. The auto ignition temperature is the lowest temperature at which the test substance will ignite when mixed with air under the conditions of the test. The method determines the minimum temperature of the inner surface of an enclosure that will result in ignition of a gas, vapour or liquid injected into the enclosure. In the case of 1,1,1,2 -tetrafluoroethane (HFC 134a) this auto-ignition temperature was found to be in excess of 743°C (1016K) at 1 atm pressure.
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.
