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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test phenomena |
1) The sample temperature could not reach 400 °C until it was heated to its melting point. 2) There was no substance in the vessel after the test completed. |
1) The sample temperature could not reach 400 °C until it was heated to its melting point. 2) There was no substance in the vessel after the test completed. |
Discuss and evaluation of analytical results
1) It can be considered as an endothermic effect from the sample melting, that Oven temperature was a little higher than Sample Temperature when the sample was heated to its melting point.
2) There was no substance in the vessel after the test completed; this could be proved that the sample in the vessel had melted and flowed away from the cribriform vessel.
3) The sample temperature could not reach 400 °C prior to that of the oven until it was heated to its melting point; it could be confirmed that the relative self-ignition temperature was above the melting point.
Analytical Conclusions
The relative self-ignition temperature of the sample is above its melting point.
Description of key information
No self-ignition observed up to the melting point (EU Method A.16)
Key value for chemical safety assessment
Additional information
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.
