Description of key information

Samarium trinitrate is concluded to be not highly flammable according to EC test method A.10. From day to day handling of the substance, samarium trinitrate is concluded not to have pyrophoric properties nor to be flammable in contact with water.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Pyrophoricity:

In the daily use and handling of samarium trinitrate during which continuous exposure to air can occur, no spontaneous ignition is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that samarium trinitrate has pyrophoric properties.

Flammability in contact with water:

Under conditions where samarium trinitrate is in contact with water no ignition and/or liberation of flammable gases is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that samarium trinitrate is flammable in contact with water.

Flammability:

An experimental study of reliability 1 according to Klimisch, performed in compliance with GLP and according to EC test method A.10, was selected as a key study. From this flammability test (EC A.10), samarium trinitrate is concluded to be not highly flammable. This results in an absence of classification both under DSD and CLP systems. Indeed, in the case of a non flammable test item, the result obtained in the A.10 test permits to conclude under both classification systems as the differences between the two methods (EC A.10 test under DSD versus UN test method N.1 under CLP) have no influence in cases where a test item is not flammable. So, it is possible to assume that a test item which does not burn under the conditions used in the EC test (DSD), will not burn in the conditions used in the UN method (CLP).
