- Executive summary:
A study was conducted to determine the auto flammability of the test substance according to EU Method A.16, in compliance with GLP.
8 cm3(4.3 g) of the test substance was placed in an oven at 25°C. The temperature/time curve relating to conditions in the centre of the sample was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/min. An exothermic reaction of the test substance occurred at a temperature of about 160°C and led to 413°C. After this, the temperature of the test substance exceeded 400°C at the oven temperature of 252°C. So the relative self-ignition temperature was 252°C.
Under the conditions of the study, the relative self ignition temperature of the test substance was found to be 252°C.
Reference
An exothermic reaction of the test substance occurred at a temperature of about 160°C and led to 413°C. After this, the temperature of the test substance exceeded 400°C at the oven temperature of 252°C. So the relative self-ignition temperature was found to be 252°C.
Description of key information
The relative self-ignition temperature of the test substance was found to be 252°C (Smeykal, 1999).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 252 °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.
