Results for the test item (1:1, test item and cellulose)
The table below summarizes the results of the 1:1 mixtures of test item with cellulose.
| Test 1 | Test 2 | Test 3 | Test 4 | Test 5 | Mean | Tolerance | |
Time [s] to 690 kPa | 26.00(1) | 29.09(1) | 23.20 | 24.45(1) | 27.24(1) | 23.20 | Minimum | Maximum |
Time [s] to 2,070 kPa | Not reached | Not reached | 44.06 | Not reached | Not reached | 44.06 | - 30 % | + 30 % |
Time for pressure rise [s] | --- | --- | 20.86 | --- | --- | 20.86 | 14.60 | 27.12 |
(1) Not used for the calculation of the mean value
Only in one out of five tests with the test item a pressure of 2,070 kPa was reached within 60 s. The time taken for the pressure to rise from 690 kPa to 2,070 kPa of test 3 is 20.86 s.
Results for the reference item (1:1, nitric acid 65% and cellulose)
The table below gives the results of the 1:1 mixtures of reference item (nitric acid 65 %) with cellulose.
| Test 1 | Test 2 | Test 3 | Test 4 | Test 5 | Mean | Tolerance | |
Time [s] at 690 kPa | 19.58 | 17.85 | 18.10 | 17.00 | 16.92 | 17.89 | Minimum | Maximum |
Time [s] at 2,070 kPa | 21.94 | 21.15 | 21.17 | 19.66 | 19.37 | 20.66 | - 30 % | + 30 % |
Time for pressure rise [s] | 2.36 | 3.30 | 3.07 | 2.66 | 2.45 | 2.77 | 1.94 | 3.6 |
The mean time taken for the pressure to rise from 690 kPa to 2,070 kPa for the reference item (nitric acid 65 %) is 2.77 s. The times taken for the pressure to rise from 690 kPa to 2,070 kPa for all 5 tests lie within the required range of ± 30 % of the arithmetic mean (1.94 s – 3.60 s).
Only in one out of five tests with the test item Triethylene glycol dimethanesulfonate a pressure of 2,070 kPa was reached within 60 s. According to the tests, the pressure rise time for the test item (20.86 s) taken from one test is greater than the mean pressure rise time for the reference item (2.77 s).
