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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- May 2018 - Jun 2018
- 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)
- Version / remarks:
- of 30 May 2008 published on 31 May 2008
- Deviations:
- yes
- Remarks:
- please refer to "Principles of method if other than guideline"
- Principles of method if other than guideline:
- The following deviation from the guideline was documented:
The heating rate slightly deviated from the value stated in the guideline of 0.5 °C/min (0.59 °C/min). This is considered as uncritical as a nominal heating rate of 0.5 °C/min was adjusted at the instrument and only a minimal deviation was observed. - GLP compliance:
- yes (incl. QA statement)
- Relative self-ignition temperature:
- 369.3 °C
- Conclusions:
- Relative Self Ignition Temperature: 369.3 °C
- Executive summary:
The study was conducted according to EU Method A.16 under GLP-conditions. An increase in the temperature of the sample in comparison to that of the oven could be detected; also signs of ignition could be observed.
The test item is considered as auto-flammable with a Relative Self Ignition Temperature of 369.3 °C under the test conditions.

An increase in the temperature of the sample in comparison to that of the oven could be detected; also signs of ignition could be observed.
The test itemis considered as auto-flammable with a Relative Self Ignition Temperatureof 369.3 ° underthe test conditions.
Description of key information
The study was conducted according to EU Method A.16 under GLP-conditions. An increase in the temperature of the sample in comparison to that of the oven could be detected; also signs of ignition could be observed.
The test item is considered as auto-flammable with a Relative Self Ignition Temperature of 369.3 °C under the test conditions.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 369.3 °C
Additional information
No pressure stated in the study report, therefore it is assumed, that room conditions dominates. Therefore 101 325 Pa are applicable for the CSA.
