Key result

Remarks on result:

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

At the start of the test, the test item was a slightly yellow crystalline solid.

At the end of the test, the cube was nearly empty; only a small part (some traces) of the test item remained. The solubilisation of the test item in its hydration water was observed between 65.5 and 87.9°C (study report No. 14-918035-001). The test item had liquefied and fallen in the small dish downside. Between approximately 320 and 550°C, the test item decomposed into rare earth oxynitrate.

Conclusions:

No self-ignition temperature of the substance was observed up to 400°C (corrected value).

Executive summary:

The self-ignition temperature of dysprosium trinitrate was investigated according to EU A.16 method in compliance with GLP. No self-ignition temperature was observed up to 400°C (corrected value).

Description of key information

Dysprosium trinitrate was concluded not to be autoflammable.

Additional information

An experimental study of reliability 1 according to Klimisch, performed in compliance with GLP and according to EU method A.16, was selected as a key study. In this study, no self-ignition temperature was observed up to 400°C (corrected value). The temperature of the test item followed the temperature of the oven throughout the test.
