- Executive summary:
The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.16. to provide preliminary information on the auto-flammability of solid substances at elevated temperatures.
The relative self-ignition temperature test for solids is performed in a temperature programmed oven of approximately 2 litres volume with natural air circulation. A stainless steel wire mesh, 20 mm test cube with 0.045 mm openings is filled with the test sample.
The cube is then gently tapped and refilled until completely full. The sample temperature is monitored by a thermocouple placed in the centre of the test cube. Another thermocouple is placed between the test cube and the oven wall to monitor oven temperature. The temperature of the oven and the sample are continuously recorded while the temperature of the oven is increased to 400°C or to the melting point of the solid, if lower, at a rate of 0.5°C/min.
The temperature of the oven at which the sample temperature reaches 400°C by selfheating is called the self-ignition temperature.
The sample tracked the oven temperature until approximately 152°C (melt). At the start of the testing the sample was a white to off-white solid, on completion of the testing a metallic, shiny, grey solid remained that had seeped through the basket. No self-ignition was observed.
