Any other information on results incl. tables

Individual results
Test series of at least 5 tests each were performed with the test item and with 65 % nitric acid in 1:1 mixture, by mass, with cellulose. The cellulose was dried at 105 ± 5 °C until the weight was constant. Due to the particle size of the cellulose (approximately 60 µm) grinding and sieving was not necessary.

Reference substance
In the Table below the pressure rise times from 690 kPa_g to 2070 kPa_g for the 1:1 mixtures, by mass, of 65 % (w/w) nitric acid and cellulose are shown.

	Test 1	Test 2	Test 3	Test 4	Test 5
Time at 690 kPag in s	14.21	13.17	12.43	12.50	12.06
Time at 2070 kPag in s	20.63	19.27	17.95	18.54	17.44
Pressure rise time in s	6.42	6.10	5.52	6.04	5.38

The mean pressure rise time was 5.89 s.

Test item
In the Table below the pressure rise times from 690 kPa_g to 2070 kPa_g for the 1:1 mixtures, by mass, of the test item and cellulose are shown.

	Test 1	Test 2	Test 3	Test 4	Test 5
Time at 690 kPag in s	17.08	15.29	17.30	17.10	16.92
Time at 2070 kPag in s	44.05	37.43	39.94	39.52	39.97
Pressure rise time in s	26.97	22.14	22.65	22.43	23.05

The mean pressure rise time was 23.44 s. 
Due to the fact that the 1:1 mixture, by mass, of test item and cellulose had a mean pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % (w/w) nitric acid and cellulose the test item had no oxidizing properties and no further reference mixtures had to be measured.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The test item had no oxidizing properties under the test conditions in the sense of the UN Manual of Tests and Criteria, Test O.2.
Due to these results the substance does not have to be classified as an “oxidising liquid”, class 5.1, according to the transport regulations and chapter 2.13 according to GHS (CLP) regulations.
