Results and discussion
Relative self-ignition temperature (solids)open allclose all
- Relative self-ignition temperature:
- >= 230 °C
- Remarks on result:
- other: pure test substance
- Relative self-ignition temperature:
- >= 230 °C
- Remarks on result:
- other: 1:1 mixture of test substance with Kieselguhr
Any other information on results incl. tables
In the screening test according to Grewer with the pure test substance an exothermal effect starting at 230°C was observed, which led to a maximum product temperature of 340°C.
In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 230°C was observed. Self-heating led by a multi-step reaction to a temperature of 450°C.
In the hot storage test self-heating was observed at 180°C leading to a maximum temperature of > 500°C. Based on the determined parameters (kinetics, conductibility of temperature) a self-heating temperature of 200°C for the 1 L wire basket (10 cm x 10 cm) and a self-heating temperature of 265°C for the wir basket 2.5 cm x 2.5 cm was calculated.
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
