220°C



 

Conclusions:
An auto-ignition temperature of 220°C at 1008 hPa was determined for the substance using a relevant test method. The result is considered reliable.

Description of key information

Auto-ignition temperature: 220°C at 1008 hPa (DIN 51794)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
220 °C

Additional information

A measured auto-ignition temperature value of 220°C at 1008 hPa was determined for the submission substance using a relevant test method and in compliance with known quality system (ISO 17025). The result is considered to be reliable and is selected as key study.


 


In a secondary source to which reliability could not be assigned, an auto-ignition temperature value of 230°C at 1013 hPa was reported for the substance.
