Any other information on results incl. tables
In the screening test according to Grewer with the pure product an endothermal effect was observed in the temperature range 70 - 180°C, followed by an exothermal effect starting at 230°C. A multistage reaction was observed which led to a maximum product temperature of more than 550°C.
In the screening test with the kieselgur mixture (1:1) an endothermal effect was observed in the temperature range 70 - 140°C. At a temperature of 250 °C an exothermal effect started. Self-heating led to a temperature of approximately 650 °C
After the test the test item was black.

Applicant's summary and conclusion
- Conclusions:
- The substance has not to be classified as self-heating according to Regulation (EC) No 1272/2008, Annex I, 2.11.4
