- Executive summary:
The self-heating potential of the substance was evaluated by an experiment conducted in accordance with VDI 2263 Sheet 1 Grewer Oven test method.
The pure test item indicated a self-heating at atmospheric pressure starting at a temperature of 205 °C, which led to a maximum temperature of 365 °C. In mixture with Kieselguhr, the test item indicated a self-heating at atmospheric pressure starting at a temperature of 205 °C, which led to a maximum temperature of 410 °C.
Conclusion
Self-heating at atmospheric pressure starting at 205 °C.
Reference
In the investigation of self-ignition in the Grewer Oven the pure test item showed a self-heating starting at 205 °C to a maximum temperature of 365 °C. After having cooled down to 270 °C, the pure test item underwent another self-heating to 375 °C which proceeded relatively slowly compared to the first self-heating. After the measurement a black powder remained in the basket.
The test item in mixture with Kieselguhr showed a self-heating starting at 205 °C to a maximum temperature of 410 °C. After having cooled down to 270 °C, the test item in mixture with Kieselguhr underwent another self-heating to 375 °C which proceeded relatively slowly compared to the first self-heating. After the measurement a grey powder remained in the basket.
