Key result
Remarks on result:
no self-ignition observed up to the melting point

The cube was filled with the test item and tapped gently. Test item was added until the cube was completely filled. The cube was then suspended in the center of the oven at room temperature. The temperature was raised up to 80.1°C at a rate of 0.5°C/minute. From the obtained graph between the temperatures T1 (Test item temperature), T2 (Oven temperature) and test period time, very sharp temperature rise above the oven temperature was not observed, this indicated that the test item does not self-ignite up to the melting point of 80.1 °C.

Conclusions:
No self-ignition was observed up to the melting point of 80.1 °C.
Executive summary:

A study according to Regulation (EC) No. 440/2008 Method A.16 was conducted to determine the relative self-ignition temperature of the test item. The tests were started from ambient oven temperature. The temperature of the oven and sample were continuously recorded with a thermosensor while the temperature of the oven was increased at a rate of 0.5 °C/min up to the melting point of the test item, which was determined to be 80.1 °C. In the course of this study the test item did not self-ignite up to the melting point of the test item. Thus, no self-ignition temperature could be stated.

Description of key information

No self-ignition was observed up to the melting point of 80.1 °C.
