Key result
Test procedure:
100 mm sample cube at 140°C
Result:
negative outcome (no effect observed)

Towards the end of the test period, a slight increase in sample temperature is observed, reaching a few °C above the test temperature after 24 hours, and approximately 9°C above the test temperature after 30 hours.

Interpretation of results:
not classified based on GHS criteria
Remarks:
and not classified based on CLP criteria
Conclusions:
The substance is not a self-heating substance.
