Endpoint:
pyrophoric solids
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
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 experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Flammability:
non flammable

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 sodium metavanadate as this is a form of vanadium that is already oxidized and has an oxygen content of 35 %. Furthermore, 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. Sodium metavanadate 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). In addition, long-term industrial experience in handling shows that sodium metavanadate is not 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 sodium metavanadate 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 sodium metavanadate 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 sodium metavanadate 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 sodium metavanadate shows that it does not react with water and will not ignite with water or humid air.

Justification for classification or non-classification

Sodium metavanadate does not need to be classified according to CLP Regulation (EC) No 1272/2008 since flammability is not considered relevant based on the chemical structure and lack of functional groups.
