Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

not classified

Additional information

Flammability in contact with water

In accordance with Regulation (EC) 1907/2006, Annex XI, Section 1, a test according to A.12 (flammability in contact with water) does not need to be conducted because the substance is known to be soluble in water to form a stable mixture. Furthermore, long-term industrial experience in practical handling of cesium fluoroaluminate shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases.

Flammability of solids

In accordance with Regulation (EC) 1907/2006, Annex XI, Section 1, a test according to A.10 (flammability of solids) is not considered to be required for inorganic metal salts in which (i) the cation is in its highest possible oxidation state (e.g. Ce+1) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable of further reaction with oxygen. This substance can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3).

Pyrophoric properties

In accordance with Regulation (EC) 1907/2006, Annex XI, Section 1, a test according to A.13 (pyrophoric properties of solids and liquids) is not considered to be required, since the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied . Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air.
