Key result
Remarks on result:
no self ignition observed under the test conditions

No changes of the sample were observed on the temperature vs. time curve in the range of 0 -400ºC. See image attached.

Conclusions:
The test item does not have a relative self-ignition temperature according to test A.16 criteria.
Executive summary:

The determination of the self-ignition temperature of the test item was performed according to EU Method A.16 / DIN 51794:2003-05 (GLP study). A cube of stainless steel wire mesh was filled with the test item, suspended in the centre of the laboratory oven and heated at a constant rate of 0.5ºC/min until reaching 400ºC. 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. Based on the test results, the test item does not have a relative self-ignition temperature according to test A.16 criteria.

Description of key information
