The test item diniobium pentaoxide is classified as not undergoing spontaneous combustion when tested according to guideline 92/69/EWG method A.16. No exothermic effects were determined up to 420 °C.
Description of key information
Self-ignition is not considered to be of relevance for this substance, since this would require heat to be developed either by reaction of this substance with oxygen or by exothermic decomposition and which is not lost rapidly enough to the surroundings. As this substance contains niobium in an oxidised form, it is intrinsically not combustible and can safely be assumed not to be ignitable under the conditions given in EU-Method A.16.
The substance diniobium pentaoxide was tested according to EU Method A.16 for a Self-Ignition temperature (Section 4.12 Auto Flammability: s_Keldenich_2009_RA Nb2O5). Diniobium pentaoxide did not undergo spontaneous combustion up to a temperature of 420 °C.
In conclusion, the conduct of further experimental verification is not considered to be required (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
