Key result
Auto-ignition temperature:
485 °C
Atm. press.:
101 325 Pa
An auto-ignition temperature value of 485°C at 1013 hPa was determined fot the substance in a reliable study conducted according to an appropriate test guideline. The result is considered reliable.

Description of key information

Auto-ignition temperature: 485°C at 1013 hPa (ASTM E659-78)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
485 °C

Additional information

An auto-ignition temperature value of 485°C at 1013 hPa was determined for the substance using a relevant test method in accordance with ASTM E659-78 Test Method.

In a secondary source to which reliability could not be assigned, auto-ignition temperature value of >400°C was reported for the substance.
