Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2004-05-25
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
- Conclusions:
- No self-ignition temperature was observed until the maximum temperature of 402 °C.
- Executive summary:
A study according to Regulation (EC) No 440/2208, A.16 was performed to determine the relative self-ignition temperature of the test substance. 8 cm3 (8.1 g) of the test item was placed in an oven at 15 °C; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400 °C at a rate of 0.5 °C/min. No exothermal reaction of the test item was observed until a maximum temperature of 402 °C. An endothermic effect (melting) in the temperature range of 35 - 70 °C was observed. Thus, the test item has no relative self-ignition temperature up to the melting point.
Reference
No exothermal reaction of the test item was observed until a maximum temperature of 402 °C. An endothermic effect (melting) in the temperature range of 35 - 70 °C was observed.
Description of key information
No self-ignition temperature was observed until the maximum temperature of 402 °C (reference 4.12 -1).
Key value for chemical safety assessment

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.
