- key study
- Study period:
- 13 July 2017 to 21 July 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)

- test mixture as specified
- Remarks:
- 2:1 sample-to-cellulose ratio
- Parameter:
- preliminary test
- Remarks on result:
- slow smouldering
- Key result
- Sample tested:

- Remarks:

- Remarks:
- yellow/green flame with sparks
- Interpretation of results:
- other: Not classified in accordance with EU Criteria
- Conclusions:
- Under the conditions of this study the reaction of the test material and cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the test material is not an oxidising solid.
- Executive summary:
The oxidising properties of the test material were investigated in accordance with the standardised guideline EU Method A17, under GLP conditions.
The test material, powdered cellulose and the reference material (barium nitrate) were dried at 105 °C until constant weight was obtained. For the preliminary test the dried test material was thoroughly mixed with cellulose in the proportions, 2 of test material to 1 of cellulose, by weight and the mixture was formed, without tamping, into a small cone-shaped pile of dimensions 3.5 cm (diameter of base) x 2.5 cm (height). The pile was placed on a cool, non-combustible, non-porous and low heat-conducting base plate. The ignition source, a hot flame from a gas burner, was put in contact with the cone. The vigour and duration of the resultant reaction were observed and recorded.
The test material and cellulose mixture smouldered with sparks and grey smoke (636 seconds). On completion of testing the sample changed from black to green and had expanded by approximately 3 times its initial volume. The reference mixture burned vigorously with a yellow/green flame and sparks (54 seconds).
Under the conditions of this study the reaction of the test material and cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the test material is not an oxidising solid.

Description of key information
Under the conditions of this study the reaction of the test material and cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the test material is not an oxidising solid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
The oxidising properties of the test material were investigated in accordance with the standardised guideline EU Method A17, 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 material, powdered cellulose and the reference material (barium nitrate) were dried at 105 °C until constant weight was obtained. For the preliminary test the dried test material was thoroughly mixed with cellulose in the proportions, 2 of test material to 1 of cellulose, by weight and the mixture was formed, without tamping, into a small cone-shaped pile of dimensions 3.5 cm (diameter of base) x 2.5 cm (height). The pile was placed on a cool, non-combustible, non-porous and low heat-conducting base plate. The ignition source, a hot flame from a gas burner, was put in contact with the cone. The vigour and duration of the resultant reaction were observed and recorded.
The test material and cellulose mixture smouldered with sparks and grey smoke (636 seconds). On completion of testing the sample changed from black to green and had expanded by approximately 3 times its initial volume. The reference mixture burned vigorously with a yellow/green flame and sparks (54 seconds).
Under the conditions of this study the reaction of the test material and cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the test material is not an oxidising solid.
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.
