Reference
Preliminary Test
The mixture of test item and cellulose (2 portions of test item and 1 portion cellulose) was ignited at the tip of the cone. The vigour and duration of the resultant reaction was observed and recorded.
No vigorous reaction was observed. Grey smoke was observed during ignition with the flame. After removing of the ignition source no independent burning or glowing of the mixture of test item and cellulose was observed. After the test a residue of grey till brown colour was found on the top of the cone.
Main Test
The main test was performed with each one of the ranges of mixtures of the reference. The determined burning rates are given inTable1.

Because the burning rates of the single determinations (Table2) showed that there was no reaction zone which travelled along the pile the test item was not considered to be an oxidizing substance and no further testing was performed.
Description of key information
not oxidising
(EU method A.17)
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Diniobium Pentaoxide is not considered to be an oxidising substance because there was no reaction zone which travelled along the pile for each tested mixture of Diniobium Pentaoxide and cellulose.
Justification for classification or non-classification
The available data on oxidising properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: based on the test according to EU Method A.17 the substance is not oxidising.
