- Executive summary:
The self-ignition of a test material was investigated in a study which was performed in accordance with the standardised guideline EU Method A.16 under GLP conditions.
A volume (approximately 8 cm³) of the test material is placed in an oven at room temperature and the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven increases to 420 °Cat a rate of 0.5 °C/min.
The temperature of the oven at which the sample temperature reaches 420 °C by self heating is called the self ignition temperature for the purpose of this test.
No self ignition was observed up to 423 °C (corrected value). At the start of the test, the test material was a white powder. At the end of the test, few black traces were observed at the bottom of the cube. At the top of the oven and around the thermocouples, some test material in the form of brown, white and grey crystals and fibres were observed. The rest of the cube was empty.
Under the conditions of this study, no self ignition temperature of the test material was observed up to 423 °C (corrected value).

Additional information
The self-ignition of a test material was investigated in a study which was performed 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).
