Reference
In the pre-test, the mixture of cellulose and test item ignited with the flame of the teclu burner. The top of the taper carbonized and for a moment a small flame was burned. The flame died and the mixture carbonized forward slowly. Also, smoke was observed. No sparks and no fizzles were observed. The mixture of reference/cellulose (2.0g/1.0g) was ignited with a flame. This mixture burned with a green-orange flame. Sparkling and fizzling was observed. The mixture carbonized completely.
In the main test,all test item mixtures showed no signs of oxidising properties. The mixtures 10/90, 20/80, 30/70, 40/60, 50/50 burned with orange flame and carbonized. But the flame of mixture 60/40 died before the mark was passed and the mixtures 70/30, 80/20 and 90/10 did not ignite through the flame. The place, where the flame contacted the mixture, was carbonized. No sparkling and cracks were observed. As the burning rate was lower than the highest burning rate of the reference item mixtures, the determination of burning rate was repeated five times for each of the three mixtures test item/cellulose (10%; 20%; 30%) with the highest burning rates.
The highest burning rate of the three mixtures test item/cellulose was determined to be 3.19 mm/s. The maximum burning rate of the reference item was determined to be 3.29 mm/s.
Description of key information
The oxidising properties of Cesium Tungsten Oxide were determined in a study following EU Method A.17. The burning rates of mixtures of the test item with cellulose (10/90, 20/80, 30/70, 40/60, 50/50) were determined. The burning rates of the three mixtures with the highest burning rates were determined six times.In all tests with the test item, no signs of oxidising properties were observed and no burning rate surpassed the burning rate of the reference item/cellulose mixtures. Therefore, the test item is considered to have no oxidising properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
No signs of oxidising properties were observed in the test item/cellulose mixtures and no burning rates surpassed the burning rate of the reference item/cellulose mixtures. Therefore, the test substance does not meet the Regulation (EC) No 1272/2008 as amended criteria for classification as an Oxidising Solid.
