Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- From 09 November 2015 To 28 April 2016
- 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:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Controlled room temperature (15-25°C, below 70 RH%)
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- The test item was previously frozen at -80°C and crushed into powder. - Key result
- Relative self-ignition temperature:
- 380 °C
- Conclusions:
- In the Melting point and boiling point studies, over 240 °C the test item colour changed to brown and charred. Based on these observations, we can conclude that the test item decomposed at temperature higher or equal to 240 °C.
Therefore the relative self-ignition temperature of 380 °C observed, correspond to the self-ignition temperature of the product of degradation of the test item. - Executive summary:
A certain amount of the test substance is placed in an oven at room temperature; the temperature difference/time curve is recorded while the temperature of the oven is increased to 400°C, at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature.
The relative self-ignition temperature of the product of degradation of the test item was 380 °C.
Reference
Three replicate tests were performed.
The relative self-ignition temperature of the product of degradation of the test item was 380°C ( mean of 379, 379 and 383°C).
Description of key information
The auto flammability of the test item was determined according to recognized guideline (EU Method A.16) and under GLP. No deviation from the guideline was observed during the test.
Key value for chemical safety assessment
Additional information
In the Melting point and boiling point studies, over 240 °C the test item colour changed to brown and charred. Based on these observations, we can conclude that the test item decomposed at temperature higher or equal to 240 °C.
Therefore the relative self-ignition temperature of 380 °C observed, correspond to the self-ignition temperature of the product of degradation of the test item.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
