- Executive summary:
The relative self-ignition temperature of the test material was assessed according to EU Method A.16 and in compliance with GLP.
A piece of stainless steel wire mesh with 0.045 mm openings was cut, folded and secured with wire into an open topped cube with dimensions of 2 x 2 x 2 cm.
The cube was completely filled with the test material. The sample was then placed in the centre of the oven at room temperature. One thermocouple was placed at the centre of the cube and the other between the cube and the oven wall to record the oven temperature.
The temperatures of the oven and the sample were continuously recorded while the temperature of the oven was increased to approximately 400 °C at a rate of about 0.5 °C/min. The appearance and physical state of the test material after the test were determined.
Applying a linear increase in temperature of about 0.5 °C/min, the test material showed an exothermic reaction starting at about 264 °C. A maximum temperature of 561 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test material was carbonised and coloured black and about 88 % of the initial weight of the test material was lost.
Under the conditions of the study the test material shows a relative self-ignition temperature at about 269 °C and is considered auto-flammable.
