Results and discussion
Test results (Oxidising liquids)open allclose all
- Sample tested:
- reference mixture with 65% nitric acid + cellulose (1:1 ratio)
- Parameter:
- mean pressure rise time
- Result:
- 1.65 s
- Remarks on result:
- other: The mean value of the last five reference tests is 2.02 s. The deviation of the new reference value is -18 %.
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- 5.4 s
- Remarks on result:
- other: The time for pressure rise is between 4.6-6.5 s, the maximum deviation of the mean value is 18 %. As the times for pressure rise obtained for the test item exceed the reference value, all runs may be used for reporting.
Any other information on results incl. tables
| Mixture (1:1) | Time for Pressure Rise from 690 kPa to 2070 kPa |
| Nitric acid (65%) / Cellulose (reference) | 1.65 s |
| Test item / Cellulose No. 1 | 6.5 s |
| Test item / Cellulose No. 2 | 5.0 s |
| Test item / Cellulose No. 3 | 5.4 s |
| Test item / Cellulose No. 4 | 4.6 s |
| Test item / Cellulose No. 5 | 5.5 s |
The mean value of the last five reference tests is 2.02 s. The deviation of the new reference value is -18 %.
The mean value of all tests is 5.4 s, the maximum deviation of the mean value is 18 %. As the times for pressure rise obtained for the test item exceed the reference value, all runs may be used for reporting.
All determined values for the pressure rise from 690 to 2070 kPa of the given sample exceed the obtained value for the reference measurement. Therefore, the test item is to be classified to have no oxidizing properties according to UN-MTC.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- All determined values for the pressure rise from 690 to 2070 kPa of the given sample exceed the obtained value for the reference measurement. The sample is to be classified to have no oxidizing properties according to UN-MTC.
