Key result
Remarks on result:
no self ignition observed under the test conditions

In the Grewer oven the pure test item indicated an endothermic effect at atmospheric pressure starting at a temperature of approx. 100 °C and ending at 150°C, which cannot be considered as a self-ignition of the test item. Up to the final measured temperature of 410 °C, no self-ignition the test item could be observed.

Conclusions:
Up to the final measured temperature of 410 °C, no self-ignition the test item could be observed.
Executive summary:

The relative self-ignition temperature of the test item was determined in Grewer Oven according to UN Division 4.2 Test N.4 and VDI 2263 (1990), sheet 1.

In the Grewer oven the pure test item indicated an endothermic effect at atmospheric pressure starting at a temperature of approx. 100 °C and ending at 150°C, which cannot be considered as a self-ignition of the test item. Up to the final measured temperature of 410 °C, no self-ignition the test item could be observed.
