Any other information on results incl. tables

In the screening test according to Grewer with the pure product and the kieselgur mixture an endothermal effect was observed at an onset temperature of 230°C.. At 260°C the beginning of an exothermal process was recorded with the pure test substance leading to a temperature of 300°C. After cooling down to the oven temperature a further exothermal process was observed at an onset temperature of 340°C leading to a maximum temperature of 450°C. more than 450 °C. The kiesegur mixture showed the same behaviour as the pure test substance at an onset temperature of 340°C.

Applicant's summary and conclusion

Conclusions:
The test item is not a self-heating substance according to Regulation (EC) no 1272/2008
