Key result

Remarks on result:

no self ignition observed under the test conditions

In the investigation of self-ignition in the Grewer Oven for the pure test item an endothermic process was detected in the temperature range of 180 to 220 °C. No exothermic effect could be detected up to the maximum test temperature of 410 °C. A black foamed residue remained in the wire basket after the test.

For the test item in mixture with Kieselguhr also an endothermic process was detected in the temperature range of 190 to 230 °C. Here, an exothermic effect was observed from around 230 °C, which led to a maximum temperature of approx. 610 °C (340 °C above the corresponding temperature of the reference material).

The table below summarizes the results of the Grewer Oven experiment.

Experiment	Onset self- ignition / °C	Maximum temperature / °C
Pure test item	-	-
Test item in mixture with Kieselguhr (1:1)	Approx.. 230	610

The pure test item indicated no self-ignition at atmospheric pressure.

Conclusions:

The pure test item indicated no self-ignition at atmospheric pressure.

Executive summary:

A study was conducted to determine the self-ignition of the test item according to VDI 2263 Sheet 1 Grewer Oven (1990). In the investigation of self-ignition in the Grewer Oven for the pure test item an endothermic process was detected in the temperature range of 180 to 220 °C. No exothermic effect could be detected up to the maximum test temperature of 410 °C. A black foamed residue remained in the wire basket after the test. The pure test item indicated no self-ignition at atmospheric pressure.

Description of key information
