Results and discussion

Relative self-ignition temperature (solids)
Relative self-ignition temperature:
>= 300 °C

Any other information on results incl. tables

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.

Applicant's summary and conclusion

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
