Results and discussion
Auto-ignition temperature (liquids / gases)
- Auto-ignition temperature:
- > 177 °C
- Remarks on result:
- other: The pure test item indicated no self-ignition up to its melting point of about 177 °C.
Relative self-ignition temperature (solids)
- Relative self-ignition temperature:
- > 177 °C
- Remarks on result:
- other: The pure test item indicated no self-ignition up to its melting point of about 177 °C.
Any other information on results incl. tables
In the investigation of self-ignition in the Grewer-oven for the pure test item a small endothermic effect was observed in the temperature range from 55 – 80 °C, which can be assigned to the loss of residual moisture. A second endothermic effect was detected in the temperature range from 150 – 190 °C accompanied by a small exothermic effect. After the test the wire basket of the pure test item was empty.
For the test item in mixture with Kieselguhr a small endothermic effect was observed in the temperature range from 55 – 70 °C. An exothermic effect was detected in the temperature range from 155 – 190 °C, which led to a maximum temperature of approx. 195 °C. After the test, the wire basket of test item in mixture with Kieselguhr was half empty.
The test item has a melting point of about 177 °C accompanied by decomposition, which confirms the results of the investigation of self-ignition in the Grewer-oven.
