Reference

Reference 1

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

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

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

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Flammability:

Not considered relevant for ammonium trivanadium octaoxide based on chemical structure and lack of functional groups.

Pyrophoricity:

Ammonium trivanadium octaoxide is stable at ambient temperature and does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20 °C). Furthermore, long-term industrial experience in handling shows that ammonium trivanadium octaoxidedoes not ignite (spontaneously) (i.e. the autoignition temperature is not below room temperature) in contact with air.

In contact with water:

Ammonium trivanadium octaoxide does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Recent experimental testing for water solubility has also not reported any formation of gases. Furthermore, long-term industrial experience in practical handling of ammonium trivanadium octaoxide shows that it does not react with water and will not ignite with water or humid air.

In contact with air:

Ammonium trivanadium octaoxide is an already oxidized form of vanadium and has an oxygen content of 42 %.In addition, testing of flammability is not considered to be required for inorganic oxides in which the cation is in its highest possible oxidation state and which therefore are incapable of further reaction with oxygen. Furthermore, long-term industrial experience in handling shows that ammonium trivanadium octaoxide is not flammable. It is considered non-flammable.

Justification for classification or non-classification

Ammonium trivanadium octaoxidedoes not need to be classified for physico-chemical properties according to Directive 67/548 EEC and CLP Regulation (EC) No 1272/2008:

flammability is considerednon-relevant based on chemical structure and lack of functional groups;

explosive properties are considered non-relevant based onlack of functional groups;

oxidising properties are considered non-relevant based on the chemical structureand oxygen content
