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

6.79 g of the test item were filled into the stainless steel wire mesh cube and placed in the oven at 32 °C. The test item showed a weak endothermal effect in the temperature range of 190 - 270 °C. No further endothermal or exothermal effects were observed up to the final test temperature of 398 °C. No self-ignition temperature was observed.

Conclusions:
No self ignition temperature was observed up to the maximum test temperature 398 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A.16 (Relative self-ignition temperature for solids) to determine the self-ignition temperature of the test substance. In a preliminary test a weak endothermal effect in the temperature range of 190 - 270 °C was observed. No further endothermal or exothermal effects were observed up to the final test temperature of 398 °C. No self-ignition temperature was observed. No observations were made which might cause doubts concerning the validity of the study outcome.Thus, the validation criteria were fulfilled.

Description of key information

No self-ignition temperature was observed up to the maximum test temperature 398 °C.

Key value for chemical safety assessment

Additional information

A study was conducted according to Regulation (EC) No 440/2008 Part A.16 (Relative self-ignition temperature for solids) to determine the self-ignition temperature of the test substance (reference 4.12-1). In a preliminary test a weak endothermal effect in the temperature range of 190 - 270 °C was observed. No further endothermal or exothermal effects were observed up to the final test temperature of 398 °C. No self-ignition temperature was observed. No observations were made which might cause doubts concerning the validity of the study outcome.Thus, the validation criteria were fulfilled.
