Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 1998
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Basic data given
- Principles of method if other than guideline:
- Grewer screening test according to company guideline and hot storage tests
- Relative self-ignition temperature:
- ca. 230 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of ca.1013.0 hPa
- Conclusions:
- The test substance shows self-ignition at 230 °C.
- Executive summary:
Self-ignition of the test substance was determined by heating a sample in the Grewer oven. The test substance shows self-ignition at 230 °C. In additional hot storage tests, the test substance showed self-heating up to 336 °C at a storage temperature of 200 °C and self-heating of 5 °C above oven temperature at 180 -190 °C.
Reference
Self-ignition of the test item in the Grewer-oven was observed at 230 °C (temperature rise up to ca. 330 °C).
The hot storage test at 180 °C showed a small temperature rise to 195 °C 1 -2 hours after temperature equalisation (which took 3.6 h) and cooled down to ca. 185 °C ca. 6 hours later. The storage temperature was then increased in the same test to 190 °C, which resulted in sample warming to 195 °C within 3 hours after temperature increase. The sample remained at ca. 195 °C until the rest of the test (total duration ca. 66 h)
In the hot storage test at 200 °C the test substance showed self-heating to 336 °C within 198 min after temperature equalisation (which took 3.4 h).
Description of key information
Self-ignition of the test substance was determined by heating a sample in the Grewer oven. The test substance shows self-ignition at 230 °C. In additional hot storage tests, the test substance showed self-heating up to 336 °C at a storage temperature of 200 °C and self-heating of 5 °C above oven temperature at 180 -190 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 230 °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.
