Description of key information
Campbell et al. (1993, liquid): Under the conditions of this study, the auto-ignition temperature was determined to be 495 ± 5 °C.
Campbell et al. (1993, solid): Under the conditions of this study, no ignition was detected before the sample melted.
Löffler (1991): Under the conditions of this study, the test material was determined to have an auto-ignition temperature of 270 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 221.85 °C
Additional information
Three studies are available to address this endpoint and all are considered to be key. Due to the low melting point of the solid substance, methods of determination of auto flammability for both solids and liquids were employed.
Campbell et al. (1993, liquid)
The auto-ignition temperature of the test material was investigated in accordance with the standardised guideline EU method A.15 reference 6.1, using IEC 79-4, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Although the test material has a low melting point, it was a solid at room temperature and could not be tested by injection using a syringe, as specified for liquids in the guideline. Instead the tests were carried out using an equivalent technique of dropping the material into the test flask in its solid state using a range of sample weights.
The final tests to establish the ignition/no ignition temperatures were made at 5 °C increments. Each series of tests, covering a range of sample weights, was carried out five times to demonstrate a repeatability of ± 5 °C.
Under the conditions of this study, the auto-ignition temperature was determined to be 495 ± 5 °C.
Campbell et al. (1993, solid)
The auto-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.16, reference 6.1, under GLP conditions. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
No ignition was detected before the sample melted, as indicated by an endotherm at approximately 65 °C.
Under the conditions of this study, no ignition was detected before the sample melted.
Löffler (1991)
The auto-ignition temperature of the test material was investigated in accordance with the standardised guidelines EU Method A.15 and DIN 51794 under GLP conditions.
The method determines the minimum temperature of the inner surface of an enclosure that will result in ignition of a gas, vapour or liquid injected into the enclosure.
Under the conditions of this study, the test material was determined to have an auto-ignition temperature of 270 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
