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

Assay No.1

Observations/results:

At the start of the test, the test item was composed of crystalline white agglomerates.

At the end of the test, the test item had liquified.

No self-ignition temperature of the test item was observed up to 400°C.

Assay No. 2

Observations/results:

At the start of the test, the test item was composed of crystalline white agglomerates.

At the end of the test, the test item had liquified.

No self-ignition temperature of the test item was observed up to 400°C.

Conclusions:
No self-ignition temperature of the test item was observed up to 400°C.

Description of key information

Yttrium trinitrate was concluded not to be autoflammable under the conditions of the EC A.16 test performed under GLP conditons (Demangel, 2012; Klimisch 1).

Key value for chemical safety assessment

Additional information

No self-ignition temperature of the test item was observed up to 400°C.
