- Guideline:
- other: Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of th Tests and Criteria, 6 edition, New York and Geneva, 2015: Appendix 6 Screening Procedures, Division 4.2: Substances which may be liable to spontaneous combustion
- Version / remarks:
- 2015
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263 (1990), sheet 1, Grewer Oven
- Version / remarks:
- 1990
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- >= 390 - <= 420 °C
- Remarks on result:
- no self-ignition observed up to the melting point
- Conclusions:
- The pure test item TA-1 indicated a self-heating at atmospheric pressure starting at a temperature of 390 °C that led to a maximum temperature of 420 °C.
According to this result of the tests on the self-ignition in the Grewer Oven the test item is classified as follows:
UN Transport Regulation: The test item is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
GHS I CLP Regulation EC 1272/2008 Annex 1: 2.11: The test item is not classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11, respectively.
Reference
In the investigation of self-ignition in the Grewer Oven the pure test item showed two small endothermic effects in the temperature ranges of 270 - 280 °C and 350 - 360 °C. An exothermic effect was detected starting at a temperature of 390 °C, which led to a maximum temperature of approx. 420 °C (10 K above the corresponding temperature of the reference material). After the test a grey residue was left inside the wire basket.
Description of key information
The pure test item TA-1 indicated a self-heating at atmospheric pressure starting at a temperature of 390 °C that led to
a maximum temperature of 420 °C.
According to this result of the tests on the self-ignition in the Grewer Oven the test item is classified as follows:
The test item is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
The test item is not classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 390 °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.
