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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03/02/2016 and 11/03/2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- GLP compliance:
- no
- Other quality assurance:
- other: ISO 9001-2008
- Remarks:
- TECNIO network
- Key result
- Relative self-ignition temperature:
- 472 °C
- Conclusions:
- The relative self-ignition of the substance occurs at 472ºC
- Executive summary:
A first DSC has been done and the sample has shown a first wide endothermic phenomenon starting at 49ºC with an associated heat of 120.8 J/g and a second endothermic phenomenon starting at 195ºC with an associated heat of 26.8 J/g. Next, an exothermic phenomenon is observed starting at 282ºC with an associated heat of 481 J/g and another exothemic phenomenon is observed starting at 472ºC with an associated heat higher than 1116.9 J/g.
In view of these resultst, the same sample has been analysed by DSC-HP (in inert atmosphere, nitrogen) and has showed an exothermic phenomenon starting at 278ºC with a peak at 289ºC and an associated heat of 477 J/g which could be attributed to the thermal decomposition of the substance.

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.
