Key result
Relative self-ignition temperature:
267 °C

At the oven temperature 150 ºC, the temperature in the sample reached 348 ºC. The next temperature increase in the sample to 385 ºC occurred at the oven temperature 215 ºC. The sample temperature exceeded 400 ºC at the oven temperature of 267 ºC, which according to the criteria of the method A.16 is determined to be the relative self-ignition temperature of the sample. See image attached.

Conclusions:
The relative self-ignition temperature of the tested material is 267 ºC according to EU method A.16 criteria.
Executive summary:

The determination of the self-ignition temperature of the tested material was performed according to EU Method A.16 (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. According to the test method, the relative self-ignition temperature of the tested material was determined to be 267 ºC.
