Reference
Individual results
Grinding, sieving and drying of the test item, barium nitrate, cellulose
The cellulose was dried by treating the sample at 105 °C±5 °C until the weight was constant. Due to the particle size of the cellulose grinding and sieving was not necessary. The barium nitrate was ground, sieved < 0.12 mm and dried by treating the sample at 105 °C ± 5 °C until the weight was constant. The test item was a solidified melt with a low melting range (sponsor's information). Therefore the test item was only ground with a mortar and sieved < 0.5 mm. The test item was dried by treating the sample at room temperature under vacuum until the weight was constant.
Preliminary test
Three test mixtures with the test item and cellulose 2:1 burned down completely in 289 s, 314 s and 310 s. Three test mixtures with barium nitrate and cellulose 2:1 burned down completely in 59 s, 55 s and 56 s. Due to the results of the preliminary test the main test had to be performed.
Main test
Four tests were performed for the reference mixture (barium nitrate and cellulose) with 50, 55, 60 and 70 wt. % of oxidizer (barium nitrate).

The highest burning rate of 1.59 mm/s was found for the mixture with 60 wt. % of oxidizer.
Mixtures of the test item with cellulose were prepared in different percentages.

Due to the fact that the maximum burning rate of the mixtures of the test item with cellulose is lower than the maximum burning rate of the reference mixture, six tests were performed with the three mixtures with the highest burning rates of 10, 20 and 30 wt.% of test item to verify these values.

The maximum burning rate of the mixtures of the test item and cellulose (1.03 mm/s) was less than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.59 mm/s).
Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, it was concluded that the test item has no oxidizing properties.
Description of key information
The test item, technical substance, had no oxidizing properties in the sense of the Method A. 17.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
The test substance does not contain oxygen components capable of oxidising combustible materials
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 chemical structure the substance is not oxidising.
