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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study (VDI 2263).
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263
- Relative self-ignition temperature:
- 270 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of ca.1013.0 hPa
- Conclusions:
- The pure test substance showed self-heating starting from 270 °C. The test item is not a self-heating substance according to UN class 4.2 and GHS/CLP.
- Executive summary:
Self-heating of the test substance was analysed by a screening test in the Grewer oven according to VDI 2263, sheet 1. The pure test substance showed self-heating starting from 270 °C. The test item is not a self-heating substance.
Reference
The pure sample showed self-heating starting from 270 °C (max. temp. ca 380 °C).
It liquefied during the test and flowed partially out of the basket. The remaining amount in the wire basket showed self-ignition.
The mixture with kieselguhr (1:1; prevents the sample from running out of the wire basket) showed self-ignition starting from 290 °C with a temperature rise to above 650 °C due to an oxidation reaction of the test substance with kieselguhr.
Description of key information
Self-heating of the test substance was analysed by a screening test in the Grewer oven according to VDI 2263, sheet 1. The pure test substance showed self-heating starting from 270 °C. The test item is not a self-heating substance.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 270 °C
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.
