Powdered test material and cellulose were mixed in a 2:1 ratio and formed into a cone (approximately 3.5 cm diameter at the base and 2.5 cm high) on a non-porous, non-combustible board. The cone was ignited with an air-rich Bunsen burner flame and the mode, vigour and duration of the reaction recorded.
The cone immediately ignited and flared with a bright orange flame. The cone fully combusted within 2 seconds leaving a black fluffy residue. The test material was determined to have oxidising properties.

Additional information
Key Study: Lammers (2019)
The oxidising properties of the test material were assessed according to EC Guideline A.17 and UN Test O.1 in accordance with the principles of GLP using reference mixtures of potassium bromate and cellulose in a 3:7, 2:3 and 3:2 (w/w) ratios. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as outlined by Klimisch et al. (1997).
The mean burning time of the 4:1 test material mixture was less than the mean burning time of the 3:2 (w/w) reference mixture. According to this, the test material has oxidising properties and is to be classified as Division 5.1 in packing group I.
Supporting Study:
The oxidising properties of the read across substance, sodium periodate, were investigated in a GLP study which was conducted in accordance with the standardised guideline EU Method A.17. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as outlined by Klimisch et al (1997), however, since the data is available on a read across substance an overall reliability score of 2 is considered appropriate. Sodium periodate is considered to be a suitable substance for read across since it is the sodium salt of periodic acid.
During the study, powdered test material and cellulose were mixed in a 2:1 ratio and formed into a cone (approximately 3.5 cm diameter at the base and 2.5 cm high) on a non-porous, non-combustible board. The cone was ignited with an air-rich Bunsen burner flame and the mode, vigour and duration of the reaction recorded.
The cone immediately ignited and flared with a bright orange flame. The cone fully combusted within 2 seconds leaving a black fluffy residue. The test material was determined to have oxidising properties.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material requires classification for oxidising properties as Category 1 (H271; May cause fire or explosion, strong oxidiser).
