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:
- 2002
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Acceptable, well-documented study report which mets basic scientific principles.
- Principles of method if other than guideline:
- Screening test according to Grewer and according to company guideline, similar to VDI 2263 sheet 1
- Relative self-ignition temperature:
- 260 °C
- Remarks on result:
- other: Weak self-heating at 260 °C due to thermal decomposition
- Conclusions:
- The test substance shows weak self-heating in the Grewer oven at 260 °C and in the hot storage test at 200 °C. No classification as a self-heating substance class 4.2 of the transport regulations required.
- Executive summary:
Self-ignition of the test substance was determined by Grewer oven screening and a hot storage test.. The test substance shows weak self-heating in the Grewer oven at 260 °C and in the hot storage test at 200 °C.
Reference
Weak self-heating at 260 °C due to thermal decomposition was observed in the Grewer oven screening.
The hot storage test showed weak self-heating of 5 °C (Tmax: 205°C) within 48 min after temperature equalisation (which took 3 hours). Partial decomposition was observed (dark discoloration).
Description of key information
Self-ignition of the test substance was determined by Grewer oven screening and a hot storage test.. The test substance shows weak self-heating in the Grewer oven at 260 °C and in the hot storage test at 200 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 200 °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.
