Results
Preliminary test
Three test mixtures with the test item and cellulose 2:1 burned for 196, 206 and 215 s respectively. After that the flame extinguished and the cone glowed down a total time of approx. 250 – 270 s.
Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 59 s, 57 s and 60 s.
Due to the results of the preliminary test the full 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 results are shown in the following table.

The highest burning rate of 1.61 mm/s was found for the mixture with 60 wt. % of oxidizer.
Mixtures of the test item with cellulose were prepared in 10 % increments between 10 and 80 wt. % and 100 wt. % test item and tested.
The following table shows the results.

A mixture with the test item and cellulose of 90 wt. % was not tested because the 80% mixture burned a short time without propagation and the 100 % mixture melted.
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 only 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 (1.20 mm/s) was less than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.61 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.
Results
Three test mixtures with the test item and cellulose 2:1 burned for 124, 120 and 140 s respectively. The test item burned with a sooting flame.
Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 84 s, 80 s and 83 s.
Due to the results of the preliminary test the full test had to be performed.
Main test
Six tests were performed for the reference mixture (barium nitrate and cellulose) with 40, 50, 55, 60, 65 and 70 wt. % of oxidizer (barium nitrate). The results are shown in the following table.

The highest burning rate of 1.29 mm/s was found for the mixture with 55 wt. % of oxidizer.
Mixtures of the test item with cellulose were prepared in 10 % increments between 10 and
70 wt % of the test item and tested. Additional tests with 5 %, 15 % and 100 % were performed.

The maximum burning rate of the mixtures of the test item and cellulose (1.18 mm/s) was less than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.29 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
Pure grade and technical grade: not oxidising
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
The oxidising properties of the test item were determined according to EU Method A.17.
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 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification: No oxidizing properties in a test according to EU Method A.17.
