An endothermic effect was observed at 196 °C followed by exothermic decomposition at 219 °C (maximum temperature 277 °C). The residue was green hardened.

Conclusions:
Chromium trioxide is classified as not undergoing spontaneous combustion when tested according to EC Guideline A 16.
Executive summary:

The auto flammability of the sample was assessed in a GLP-study according to EU Method A.16. T An endothermic effect was observed at 196 °C followed by exothermic decomposition at 219 °C (maximum temperature 277 degC). The residue was green hardened. The substance is classified as not undergoing spontaneous combustion when tested according to EU Method A.16.
