Additional information

Flammability of solids

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, testing of flammability is not considered to be required for divanadium tris(sulphate) as it has an oxygen content of 49 %. Furthermore, long-term industrial experience in handling shows that divanadium tris(sulphate) is not flammable. It is considered non-flammable.

Pyrophoricity

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, testing for pyrophoric properties of solids is not considered to be required, since divanadium tris(sulphate) is stable at ambient temperature. This substance also 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 divanadium tris(sulphate) does not ignite (spontaneously) (i.e. the autoignition temperature is not below room temperature) in contact with air.

Flammability in contact with water In accordance with Regulation (EC) No 1907/2006 Annex XI, Section 1, testing of flammability in contact with water is not considered to be required, because divanadium tris(sulphate) 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 divanadium tris(sulphate) shows that it does not react with water and will not ignite with water or humid air.

Justification for classification or non-classification

Divanadium tris(sulphate) does not need to be classified for flammability according to Directive 67/548 EEC and CLP Regulation (EC) No 1272/2008

based on chemical structure and the lack of functional groups.
