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
