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 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	10.83	9.67	11.22	13.66	12.01
Time at 2070 kPag in s	14.54	14.50	14.75	17.46	16.34
Pressure rise time in s	3.71	4.83	3.54	3.80	4.34

The mean pressure rise time was 4.04 s. All measured values are within the tolerable range of ± 30 % (2.83- 5.25 s) of the mean pressure rise time.

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	17.72	16.72	19.76	19.37	16.05
Time at 2070 kPag in s	37.41	--	39.96	40.68	43.79
Pressure rise time in s	19.69	--	20.20	21.32	27.75

The mean pressure rise time was 22.24 s. One test was not included in the mean value because no pressure rise up to 2070 kPa_g was observed. All other measured values are within the tolerable range of ± 30 % (15.57- 28.91 s) of the mean pressure rise time.
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.
