Key result
Remarks on result:
no self ignition observed under the test conditions
Remarks:
(up to 400°C)

At the start of the test, the test item was a white powder.

At the end of the test, the cube was full of white powder.

The temperature of the test item sample followed the temperature of the oven up to the highest oven temperature reached (400°C).

Similar observations were made in the second assay.

Conclusions:
The self-ignition temperature of diytterbium trioxide was investigated according to the EU A.16 method in compliance with GLP. No self-ignition temperature was observed up to 400°C (corrected value). The temperature of the test item sample followed the temperature of the oven.

Description of key information

In a GLP study performed according to the EU A.16 method (Klimisch 1, Demangel, 2017), no self-ignition temperature was observed up to 400°C (corrected value) for diytterbium trioxide. The temperature of the test item sample followed the temperature of the oven.

Key value for chemical safety assessment
