- Conclusions:
- In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselguhra self-ignition could be oberserved at a temperature of 240 °C.
- Executive summary:
In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselguhra self-ignition could be oberserved at a temperature of 240 °C.
Based on the results of the test in the Grewer oven the test item is classified as follows:
UN Transport Regulation
The test item is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.11:
The test item is not classified as self-heating substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.11.
Reference
In the investigation of self-ignition in the Grewer-oven an endothermic process was observed for the pure test item and the test item in mixture with Kieselguhr in the temperature range of 100 to 155 C.
For the pure test item a self-ignition was observed at a temperature of 240 °C, which led to a maximum temperature of 555 °C.
In the investigation of self-ignition in the Grewer-oven for the test item in mixture with Kieselguhr a self-ignition was observed at a temperature of 240 °C, which led to a maximum temperature of 670 °C.
