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 mettalic grey powder.

At the end of the test, the cube was full of grey 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 two assays.

Conclusions:
The self-ignition temperature of yttrium metal 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

Based on an experimental study (Demangel, 2017, Klimisch score 1) performed in accordance with EU method A.16 and in compliance with GLP, it is concluded that the test item has no self-ignition temperature up to 400°C (corrected value). Within this test, the temperature of the test item sample followed the temperature of the oven. Results of this study are reliable without restrictions.

Key value for chemical safety assessment

Additional information

The test item has no self-ignition temperature up to 400°C.
