- Remarks on result:
- other: The temperature of the test substance exceeded 400°C at a corresponding oven temperature of 390°C and lead to a maximum temperature of 411°C.
- Conclusions:
- Under the study conditions, the relative self-ignition temperature of the test substance was determined to be 390°C.
- Executive summary:
A study was conducted to determine the self-ignition temperature of the test substance according EU Method A.16, in compliance with GLP.
The determination of the relative self-ignition temperature was carried out by placing 8 cm3 (3.8 g) of the test substance in an oven at 25°C. The temperature of the oven at which the test substance temperature reaches 400°C by self-heating was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/min.
No self-ignition was noted up to decomposition at 90°C. An exothermal reaction of the test substance occured at a temperature of 260°C and led to 377°C. After this peak, the temperature of the test substance was permanent over the oven temperature until 390°C, at which the temperature of the test substance exceeded 400°C and led to a maximum temperature of 411°C.
Under the study conditions, the relative self-ignition temperature was determined to be 390°C.
Reference
An exothermal reaction of the test substance occured at a temperature of 260°C and lead to 377°C. After this peak the temperature of the test substance was permanent over the oven temperature until the maximum temperature of 411°C. The temperature of the test substance exceeded 400°C at a corresponding oven temperature of 390°C and lead to a maximum temperature of 411°C.
Description of key information
Under the study conditions, the relative self-ignition temperature of the test substance was determined to be 390°C.
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).
