- 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)
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 90 s
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- > 60 s
- Remarks on result:
- maximum pressure of 2070 kPa not reached
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test mixtures failed to create a sufficient pressure increase to enable the rise time to be measured. In accordance with the criteria of UN Test O.2, the test substance is not classified as an oxidizing substance.
- Executive summary:
The oxidising properties of the substance were determined in accordance with UN Test O.2 under GLP in a valid and reliable study. The study was carried out using a cylindric steel vessel, the pressure of which was monitored by a transducer mounted in a side-arm. The transducer is capable of responding to rates of pressure rise of 690 to 2070 kPa above atmospheric pressure in not more than 5 ms. One end of the vessel was closed with a firing plug fitted with two electrodes. An ignition system was attached to the electrodes. The opposite end of the vessel was closed with a bursting disc held in place by a retaining plug. The disc has a bursting pressure of ca. 2200 kPa.
The test substance was thoroughly mixed with dried cellulose in a ratio of 1:1 by weight and the mixture was added in small portions to the vessel by packing it around the ignition coil, which was then heated by applying a current of 10 A. The mixture was heated until the bursting disc ruptured or until at least 60 s had elapsed.
The signal produced by the pressure transducer was monitored and recorded throughout the test and a time pressure profile was produced in a graphical form. The time taken for the pressure to rise from 690 to 2070 kPa above atmospheric pressure was the calculated from the graphical data.
Five tests with the 1:1 mixture of dried cellulose and substance were conducted to determine the mean pressure rise time. The mean pressure rise time was also determined for a 1:1 reference mixture of 65% aqueous nitric acid with cellulose to classify the substance. However, the test mixtures failed to create sufficient pressure increase to enable the rise time to be measured.
Reference
In each of the five tests with the test mixture, the reaction failed to produce a pressure greater than the upper threshold of 2070 kPa, in which case the rise time could not be determined. The maximum pressure in the five tests ranged from 663 to 1232 kPa.

Description of key information
The oxidising properties of the substance have been determined reliably under GLP in accordance with UN Test O.2.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The test mixtures failed to create a sufficient pressure increase to enable the rise time to be measured. In accordance with the criteria of UN Test O.2, the test substance is not classified as an oxidizing substance.
