- key study
- Study period:
- 23 March 2020 to 25 March 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline

- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- 52.93 s
- Sample tested:
- reference mixture 1: 1
- Parameter:
- mean pressure rise time
- Result:
- 2.449 s
- Interpretation of results:
- other: not classified according to EU criteria
- Conclusions:
- Under the conditions of the study, the sample of test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample, indicating that the material is not classified as an oxidising liquid.
- Executive summary:
The oxidising properties of the test material were investigated in a study which was conducted in accordance with the standardised guideline EU Method A.21 and under GLP conditions.
The test method measures the pressure rise time during deflagration. The test liquid was mixed in a 1:1 ratio (by mass) with fibrous cellulose and the mixture heated in a pressure vessel to evaluate the rate of pressure rise. The results were compared with data obtained in the same equipment for a 1:1 mixture of cellulose with a known, characterised oxidant (65 % aqueous nitric acid).
Under the conditions of the study, the sample of test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample, indicating that the material is not classified as an oxidising liquid.

The test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample, indicating that the material is not classified as an oxidising liquid.
A total of seven runs were conducted on the test material / cellulose mixture. The coil was observed to break in four of these runs. This may have been due to corrosion of the coil by the acidic test material. Since the fastest pressure rise time for the test material / cellulose mixture was significantly slower than that for the nitric acid / cellulose mixture, and the initial gradient of the graph before the coil broke was not as steep as that for the reference mixture, the test material is not considered to be an oxidising liquid.
Description of key information
Under the conditions of the study, the sample of test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample, indicating that the material is not classified as an oxidising liquid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
The oxidising properties of the test material were investigated in a study which was conducted in accordance with the standardised guideline EU Method A.21 and under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The test method measures the pressure rise time during deflagration. The test liquid was mixed in a 1:1 ratio (by mass) with fibrous cellulose and the mixture heated in a pressure vessel to evaluate the rate of pressure rise. The results were compared with data obtained in the same equipment for a 1:1 mixture of cellulose with a known, characterised oxidant (65 % aqueous nitric acid).
Under the conditions of the study, the sample of test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample, indicating that the material is not classified as an oxidising liquid.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to oxidising properties.
