101.3 kPa
An auto-ignition temperature value of 224°C at 101.3 kPa was determined for the substance in a reliable study conducted according to an appropriate test protocol. No further details are available.

Description of key information

Auto-ignition temperature:  224°C at 1013 hPa

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
224 °C

Additional information

An auto-ignition temperature value of 224°C at 1013 hPa was determined for the substance using a relevant test method. The result is considered to be reliable and is selected as the key study.

In a collection of reliable data, auto-ignition temperature value of 220°C at 1013 hPa was reported for the substance.

In available secondary sources to which reliability could not be assigned, auto-ignition temperature in the range 104°C to >185°C were reported for the substance. Variations in the auto-ignition temperature may be due to differences in the test method or differences in test substance purity.
