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 vanadium, oxalate complexes as this is a form of vanadium that is already oxidized and has an oxygen content of 52 %. Furthermore, long-term industrial experience in handling shows that the substance is not flammable. Vanadium, oxalate complexes 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 vanadium, oxalate complexes 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, oxalate complexes 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, oxalate complexes 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, oxalate complexes shows that it does not react with water and will not ignite with water or humid air.

Justification for classification or non-classification

Vanadium, oxalate complexes 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 lack of functional groups.
