Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Relative self-ignition temperature (solids)
Relative self-ignition temperature:
> 172 °C
Remarks on result:

Any other information on results incl. tables

No exothermic reactions have been observed upto and above the melting temperature. A typical response curve is attached.

After the test the cube was observed to be empty. A brown liquid was observed beneath the cube.

Applicant's summary and conclusion

The substance was determined to have an autoflammability above the melting point.
Executive summary:

The auto-flammability has been assessed by means of a gradual increase in temperature of the substance to a temperature above the melting point and minitoring any exothermic reaction by means of a thermocouple according to EU method A16 in compliance with GLP. No exothermic reaction was observed and the test sample is therefore considered to have an auto-flammability above the melting temperature.
