Key result
Remarks on result:
other: No relevant exothermic reaction/self-heating of the sample has been observed.

The test item was a dark blue powder. Whilst heating the test item, no relevant exothermic reaction/self-heating of the sample has been observed. On completion of the test, the test item was a fused black solid.

Conclusions:
The test item has been determined not to have a relative self-ignition temperature below 400 °C.
Executive summary:

The self-ignition temperature of the test substance was investigated in a study conducted according to EU Method A.16. In this study, the test substance, placed in oven, was exposed to increasing temperature from ambient to 400 °C at a rate of 0.5 °C/min. The temperature/time curves relating to the condition in the center of the sample and the oven were recorded on a data logger. Whilst heating the test substance, no relevant exothermic reaction/self-heating of the sample has been observed. Hence, the test substance has been determined not to have a relative self-ignition temperature below 400 °C.

Description of key information

The test substance has been determined not to have a relative self-ignition temperature below 400 °C.

Key value for chemical safety assessment
