Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.2 (Test for oxidizing liquids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material: 4133/00-K0
- Expiration date of the lot/batch: June 08, 2021
- Purity test date: Certificate dated from December 03, 2020, Umicore, Germany
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature (10°C to 30 °C), dark, dry
FORM OF TEST MATERIAL
- Content: Pt 1.820 % (ICP-OES)
- Form: liquid
- Appearance: Pale yellow clear liquid - Contact with:
- other: fibrous cellulose
- Duration of test (contact time):
- 10 min
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Remarks on result:
- other: in three out of the five measurements the pressure of 2070 kPa could not be reached and two measurements showed a more than 10-fold higher pressure rise time than that of a 1:1 mixture, by mass, of 65 % (w/w) nitric acid and cellulose
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 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 to GHS (CLP) regulations.
- Executive summary:
Huber-Lohr (2021) is a GLP-compliant study following UN Test O2 (liquids). It is reliable without restrictions and can be used as a key study for this endpoint.
The 1:1 mixture, by mass, of test item and cellulose had a pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % (w/w) nitric acid and cellulose. Therefore, the test item had no oxidizing properties and no further reference mixtures had to be measured.
The test item had no oxidizing properties under the test conditions in the sense of the UN Manual of Tests and Criteria, revision 7 (2019) 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 to GHS (CLP) regulations.

Remark: * No value could be measured as the corresponding pressure was not reached within the timeframe of the test.
Since for the 1:1 mixture, by mass, of test item and cellulose in three out of the five measurements the pressure of 2070 kPa could not be reached and two measurements showed a more than 10-fold higher pressure rise time 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.
Description of key information
The test item had no oxidizing properties under the test conditions in the sense of the UN Manual of Tests and Criteria, revision 7 (2019) Test O.2.
