- Relative self-ignition temperature:
- >= 220 °C
- Remarks on result:

- Relative self-ignition temperature:
- >= 240 °C

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 80 - 220°C, followed by an exothermal effect starting at 220°C. A multistage reaction was observed which led to a maximum product temperature of more than 700°C.
In the screening test with the kieselgur mixture (1:1) a self-heating was detected at 240 °C. A multistage reaction was observed which led to a maximum product temperature of more than 600 °C
After the test the the pure product consisted of green an black residues.

Applicant's summary and conclusion
- Conclusions:
- The test item has not to be classified as self-heating substance according to Regulation (EC) No 1272/2008, Annex I, 2.11.4
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
