Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Relative self-ignition temperature:
- >= 240 °C
- Remarks on result:
- other: pure test substance
Any other information on results incl. tables
In the screening test according to Grewer with the pure test substance an endothermal effect was observed in the temperature range 80 - 240°C, followed by an exothermal effect starting at 240°C. The heat production led to a maximum test substance temperature of more than 400°C.
In the screening test with the kieselgur mixture (1:1) only a small exothermal effect was recorded starting at 240°C.
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
