STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature, under nitrogen in the dark - Key result
- Relative self-ignition temperature:
- 351 °C
- Conclusions:
- Under the conditions of this study the test material has been determined to have a relative self-ignition temperature of 351 °C.
Reference
The test material was a light grey powder. Whilst heating the test material, no relevant exothermic reaction/self-heating of the sample has been observed. On completion of the test, the test material was an off white solid.
Description of key information
Under the conditions of this study the test material has been determined to have a relative self-ignition temperature of 351°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 351 °C
Additional information
The relative self-ignition temperature of the test material was determined in accordance with the standardised guideline EU Method A.16 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
A cube was completely filled with the test material and placed in the centre of the oven at room temperature. A thermocouple was placed in the centre of the sample and another in the oven. The oven temperature was programmed to increase from ambient to 400°C at a rate of 0.5°C/min. The temperature/time curves relating to the condition in the centre of the sample and the oven were recorded on a data logger. Before and after the test the appearance of the test material was recorded.
The test material was a light grey powder. Whilst heating the test material, no relevant exothermic reaction/self-heating of the sample has been observed. On completion of the test, the test material was an off white solid.
Under the conditions of this study the test material has been determined to have a relative self-ignition temperature of 351°C.
