Relative self-ignition temperature (solids)
- Relative self-ignition temperature:
- > 400 °C
Any other information on results incl. tables
There was no flame observed arising out from the sample cube or steep rise in the temperature of the test item when the oven temperature was raised up to 400°C with a controlled heating. It was observed that the test item did not ignite below 400°C.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
