- UN Manual of Tests and Criteria: Test O.2 (Test for oxidizing liquids)
- Version / remarks:
- UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Revision 6, Part III, UN test O.2.
Depending on the results 65 % nitric acid, 40 % sodium chlorate (aqueous solution) and 50 % perchloric acid will be used as reference items for the oxidising properties. - Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on 20 and 21 June 2017 / signed on 04 September 2017
- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Remarks on result:
- maximum pressure of 2070 kPa not reached
- Sample tested:
- reference mixture with 65% nitric acid + cellulose (1:1 ratio)
- Parameter:
- mean pressure rise time
- Result:
- 5.25 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item had no oxidizing properties under the test conditions.
- Executive summary:
A study was conducted under GLP according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Revision 6, Part III, UN test O.2. Due to the obtained results the substance does not have to be classified as an “oxidizing liquid”, class 5.1, according to the transport regulations and chapter 2.13 according to GHS (CLP) regulations.
Reference
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 Table1the pressure rise times from 690 kPagto 2070 kPagfor the 1:1 mixtures, by mass, of 65 % (w/w) nitric acid and cellulose are shown.Figure1(page8) shows the time pressure profile.

No pressure rise up to 2070 kPagwas detected in any test.
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.
Final results
The test item had no oxidizing properties under the test conditions in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Test O.2.
Due to these results the substance does not have to be classified as an “oxidizing liquid”, class 5.1, according to the transport regulations and chapter 2.13 according to GHS (CLP) regulations.
Description of key information
The test item had no oxidizing properties under the test conditions.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
A GLP fully reliable experimental study was conducted according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Revision 6, Part III, UN test O.2, will be available. Therefore, it is considered as a key study. The result is retained as key data.
Justification for classification or non-classification
The test item had no oxidizing properties under the test conditions in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Test O.2.
Due to these results the substance does not have to be classified as an “oxidizing liquid”, class 5.1, according to the transport regulations and chapter 2.13[1] according to GHS (CLP) regulations.
