Any other information on results incl. tables
Grinding, sieving and drying of the test item, barium nitrate and 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 ground, sieved < 0.12 mm and dried by treating the sample at 105 °C +/- 5 °C until the weight was
constant.
Preliminary test
Three test mixtures with the test item and cellulose 2:1 burned only for approximately 20s. Afterewards the flames extinguished. Subsequently the cones glowed for more than 15 min.
Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 58 s, 60 s and 63 s, respectively. 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. % oxidizer (barium nitrate). The results are shown in Table 1:

The highest burning rate of 1.77 mm/s was found for the mixture with 60 wt. % oxidizer.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The mixture of the test item with cellulose showed a lower burning rate than the reference mixture. Therefore, the test item has not to be classified as oxidizing solid according to Regulation (EC) No 1272/2008.
