 No endothermic or exothermic reaction was observed during the performance of the test. The test substance had melted and changed into a black residue.

Conclusions:

The test item is not self-ignitable.

Executive summary:

The determination of the relative self-ignition temperature of the test item was performed in accordance with EEC-Directive 92/69 EEC, A.16 "Relative self-ignition temperature for solids" (1992).

Approximately 8 cm^3 test substance was heated in an oven. The temperature rise of the oven was 0.5 °C/min. The temperature of the sample and the oven were registered simultaneously. The test was started at room temperature and terminated at 400 °C. No endothermic or exothermic reaction was observed during the performance of the test.

In conclusion, the test item is not self-ignitable, according to the criteria as described in the method A.16 of EEC-Directive 92/69 EEC.

Description of key information
