Description of key information
Auto-ignition temperature: 314°C at 957.3 to 975.1 hPa (DIN 14522, Method S)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 314 °C
Additional information
An auto-ignition temperature value of 314°C at 957.3 to 975.1 hPa was determined for the substance using a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.
In an available secondary source to which reliability could not be assigned, an auto-ignition temperature of 295°C at 1013 hPa was reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
