Description of key information

Auto-ignition temperature (hexamethyldisiloxane): 340°C (EU MethodA.15)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
340 °C

Additional information

A measured auto-ignition temperature of 340°C was determined for the substance using an appropriate test method, although full details are not available, the result is considered to be reliable and is selected as key study. This is supported by auto-ignition temperatures of 340°C and 362°C using relevant methods. In secondary sources to which reliability could not be assigned, auto-ignition temperatures of 310°C and 420°C were reported for the substance.
