Vanadium oxide sulphate is not considered as highly flammable.
Vanadium oxide sulphate is not pyrophoric.
Vanadium oxide sulphate does not emit flammable gases in contact with water.
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 vanadium oxide sulphate, as this is a form of vanadium that is already oxidized and has an oxygen content of 49 %. Furthermore, long-term industrial experience in handling shows that vanadium oxide sulphate is not flammable. Thus, it is considered non-flammable.
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 vanadium oxide sulphate is stable at ambient temperature. It 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 (ca. 20 °C). Furthermore, long-term industrial experience in handling shows that vanadium oxide 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 vanadium oxide 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 vanadium oxide sulphate shows that it does not react with water and will not ignite with water or humid air.
Vanadium oxide 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.
