Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Link to relevant study record(s)

relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Guideline method conducted in a reliable laboratory within the spirit of GLP, but without GLP certification.
according to guideline
ASTM E659 (Standard test method for autoignition temperature of liquid chemicals)
GLP compliance:
yes (incl. QA statement)
Key result
Relative self-ignition temperature:
300 °C
Remarks on result:
other: at 100 kPa
reported as 1000 mbar
The auto-ignition temperature of the test material was found to be 300°C at 100 kPa.

Description of key information

300 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
300 °C

Additional information

In a guideline autoignition test protocol, the substance was found to ignite at temperatures over 300 °C. In a different study, dust explosivity risk was evaluated as strong, with a high sensitivity to ignition.
