Results
The results of the Grewer Oven experiment are summarized in the next table.

In the investigation of self-ignition in the Grewer Oven for the pure test item a small exothermic effect started at 220 °C and increased to 245 °C, directly followed by an endothermic process. After this the temperature of the test item was permanent over the reference temperature (6 - 8 K) until the maximum temperature of 420 °C (415 °C reference temperature). This effect is explained to changing the condition of the pure test item. After the measurement the test item was fluffy.
For the test item in mixture with Kieselguhr a small exothermic effect was observed at 220 °C and the temperature increased to 245 °C. After this the temperature is fallen down to the reference temperature. Above 250 °C a permanent temperature rise was observed until the maximum temperature of 450 °C (415 °C reference temperature).
Final Results / Classification
The pure test item indicated a slight self-heating but no self-ignition at atmospheric pressure until the maximum test temperature of 420 °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 420 °C (Grewer Oven preliminary test)
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
