In all tests with the test item and Cellulose in the ratio 4:1, the mixture decomposed flameless very slowly over the complete pile. In each case, the power supply was switched off after 3 min.

In all tests with the test item and Cellulose in the ratio 1:1, the mixture decomposed with a light bluish flame very slowly over the complete pile. In each case, the power supply was switched off after 3 min.

The mean burning times of the test item-to-Cellulose ratio 4.1 and 1:1 were significantly greater than the mean burning time of a 3:7 mixture of Potassium bromate and Cellulose.

Interpretation of results:
GHS criteria not met
Conclusions:
UN-Transport regulations
The product does not need to be classified as oxidizing solid in Division 5.1 according to the UN-Transport Regulations.

GHS and EC 1272/2008 (CLP-Guideline)
The product does not need to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP-Guideline) Annex 1: 2.14.

Description of key information

Divanadium pentaoxide is not oxidising.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Divanadium pentaoxide (having an oxygen content of 44%) is not oxidising according to the experimental determination of oxidizing properties according to UN-Test O.1. Thus, other vanadium oxides with lower or similar oxygen content are not expected to have oxidising properties either.

Justification for classification or non-classification

Divanadium pentaoxide (having an oxygen content of 44%) is not oxidising according to the experimental determination of oxidizing properties according to UN-Test O.1.

Divanadium pentaoxide does not need to be classified as oxidizing solid in Division 5.1 according to the UN-Transport Regulations and to GHS and EC 1272/2008 (CLP-Guideline) Annex 1: 2.14.
