Reference
In the investigation of self-ignition in the GREWER oven for the pure test item an endothermic effect could be observed at a temperature of 120°C followed by an exothermal process starting at 260°C and leading to a maximum temperature of appr. 460°C.
For the test item in mixture with Kieselguhr an endothermic effect could be observed at a temperature of 120°C an an exothermal process was determined at a temperature of 260°C leading to a maximum temperature of appr. 400°C.
Description of key information
Measurement acc. A16 (440/2008/EC) with GREWER oven.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 329 °C
Additional information
A classification as self-heating substance can be excluded
