- Specific details on test material used for the study:
- - Storage conditions: Room temperature over silica gel in the dark
- Key result
- Relative self-ignition temperature:
- 340 °C
- Conclusions:
- Under the conditions of the study, the relative self ignition of the test material was 340 °C.
- Executive summary:
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 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 pink powder. Whilst heating the test material, exothermic reaction/self-heating of the sample was observed. On completion of the test, the test material was an off white solid.
Under the conditions of the study, the relative self ignition of the test material was 340°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).
