Results
In the investigation of self-ignition in the Grewer Oven for the pure test item an endothermic effect was observed in the temperature range of 200 – 260 °C. After approx. 270 °C the temperature of the test item was permanent over the reference temperature (6 – 10 K) up to the maximum temperature of 420 °C (410 °C reference temperature). This effect is explained to the empty basket. After the measurement the test item was empty.
For the test item in mixture with Kieselguhr neither endothermic nor exothermic effect was observed up to maximum test temperature of 410 °C.

Final
Results/Classification
The pure test item indicated no self-ignition at atmospheric pressure up
to the maximum test temperature of 410 °C.
UN Transport Regulation: The test item has not to be classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11: The test item has not to be classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11.
Description of key information
No self-ignition up to 410 °C (Grewer oven test).
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
