Executive summary:

The study was performed according to the Guideline EEC A. 16 (GLP). Test item was filled in cube and suspended 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 oven wall to record the oven temperatures. The temperature of the oven was increased to 400 °C at a rate of 0.5 °C/minute. The temperatures of the oven and sample were continuously recorded up to 400 °C.

The results were interpreted on the basis of temperature / time curve. The curve shows that the temperature of sample and oven are relatively same to each other. From the curve it was evident that sample of test item did not ignite as no any sudden rise of sample temperature over oven temperature was observed.

Based on the results obtained from the study, it is concluded that the relative self-ignition temperature of the test item can be considered to be greater than 400 °C.
