- Executive summary:
The self-ignition behavior of the product is determined in the Grewer Oven according to VDI 2263, sheet 1.
In the investigation of self-ignition of the pure test item in the Grewer Oven showed one small endothermic effect in the temperature range of 45 °C up to 120 °C and one exothermic effect. The pure test item showed a self-heating starting at 275 °C to a maximum temperature of 440 °C. After the measurement a black powder remained in the basket.
For the test item in mixture with Kieselguhr one small endothermic effect in the temperature range of 45 °C up to 120 °C was detected, too: Up to an oven temperature of 400 °C no self-heating occured. After the measurement a light grey residue remained in the basket.
Conclusion
On the basis of the results of the screening test on the self-ignition in the Grewer Oven, the test item is not a self-heating substance according to UN Transport Regulation.
