Principles of method if other than guideline:
Differential thermal analysis (DTA)
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
>= 310 °C

the test substance decomposes at an onset temperature of 310°C (peak 314°C) without melting; decomposition energy 240 J/g

Conclusions:
The test substance decomposes at an onset temperature of 310 °C without melting.

Guideline:
other: Directive VDI 2263, part 1
Relative self-ignition temperature:
>= 300 °C

The neat sample and the sample with kieselguhr show self-ignition in the Grewer oven starting at 300 °C. A multi-stage reaction leading to a temperature of more than 600°C was recorded.

Conclusions:
The test substance shows self-ignition at 300 °C. Therefore, the test material is not a self-heating substance according to Regulation (EC) 1272/2008
