Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 2019-03-26 to 2019-03-28
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study performed to EU Method with no significant deviations and run in OECD GLP certified lab.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Purity: 98%
Batch No.: 800327680 - Contact with:
- powdered cellulose
- Duration of test (contact time):
- <= 60 s
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- 78.907 s
- Remarks on result:
- spontaneous ignition does not occur
- Interpretation of results:
- other: non oxidising
- Conclusions:
- The substance is not considered to be an oxidising liquid.
- Executive summary:
The oxidizing test of the test substance was measured according to EU Method A.21 (Oxidising Properties (Liquids)).
In total, six tests were conducted on the test item and cellulose mixture. In five of these tests the coil was observed to break before a pressure of 2070 kPa was achieved (possibly due to corrosion by the bromine present in the sample). In one of the tests a pressure of 2070 kPa was achieved, however the coil also broke in this test and the time taken to reach 2070 kPa was longer than it otherwise would have been.
Based on the gradient of the graph before the coil broke the sample is not considered to be an oxidising liquid.

Description of key information
The oxidizing test of the test substance was measured according to EU Method A.21 (Oxidising Properties (Liquids)).

In one of the tests a pressure of 2070 kPa was achieved, however the coil also broke in this test and the time taken to reach 2070 kPa was longer than it otherwise would have been.
Based on the gradient of the graph before the coil broke the sample is not considered to be an oxidising liquid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
In accordance with Regulation (EC) No. 1272/2008 section 2.13 Table 2.13.1, a substance or mixture shall not be classified as oxidizing if any substance or mixture which, in the 1:1 mixture, by mass, of substance (or mixture) and cellulose tested, exhibits a mean pressure rise time less than or equal to the mean pressure rise time of a 1:1 mixture, by mass, of 65 % aqueous nitric acid and cellulose; and the criteria for Category 1 and 2 are not met.
As a 1:1 mixture of the substance and cellulose exhibited a mean pressure rise time longer than the mean pressure rise time of a 1:1 mixture of 65 % aqueous nitric acid and cellulose, the substance should not be classified for oxidising liquid.
