- key study
- Study period:
- 23 August 2012 - 29 August 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- other: Test O.1 of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, 5th revised edition 2009
- Deviations:
- yes
- Remarks:
- see below
- Principles of method if other than guideline:
- The electrical resistance of the ignition wire used was 3.9 Ω/m, which is a deviation from the electrical resistance of 6.0 ± 0.5 Ω/m specified in the Method O.1. However, the material (Nickel/Chromium), length (30 cm) and diameter (0.6 mm) of the wire met the method specifications. In addition, the appropriate combination of current and voltage was used to ensure that the electrical power dissipation in the wire (150 ± 7 W) also met the method specifications. Therefore, as the physical parameters of the wire and the power dissipation (i.e. the heat applied to the test) meet the method specifications, the deviation from the electrical resistance of the wire had no effect on the test.

- other: no oxidising properties
- Conclusions:
- Under the conditions of this study, the test material has been determined not to be an oxidising solid and requires no classification in accordance with EU criteria.
- Executive summary:
The oxidising properties of the test material were investigated using a procedure designed to be compatible with Test O.1 of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, 5th revised edition 2009 and Section 2.14 of Regulation (EC) No 1272/2008 of 16 December 2008 on Classification Labelling and Packaging of Substances and Mixtures.
The burning time of test material/cellulose mixtures (4:1 and 1:1 ratio by mass) were compared with the burning time of potassium bromate/cellulose mixtures (3:7 ratio by mass).
The mean burning times obtained for the mixtures of test material and cellulose were greater than the mean burning time of potassium bromate/cellulose mixtures (3:7 ratio by mass).
Under the conditions of this study, the test material has been determined not to be an oxidising solid and requires no classification in accordance with EU criteria.

Discussion
The ignition wire broke during each of the tests for the mixtures of test material and cellulose. Breaking of the ignition wire often occurs with test material and cellulose mixtures but this is not the case for the reference mixtures. Test O.1 states that if the wire breaks during the test, then the test should be repeated unless the wire breaking clearly does not affect the result. In each case that the wire broke, it was judged not to have affected the test.
As the mean burning times for the mixtures of test material and cellulose were greater than the mean burning time for the 3:7 (by mass) mixture of potassium bromate and cellulose, it was not necessary to determine the mean burning times for the faster burning reference mixtures.
Description of key information
The test material has been determined not to be an oxidising solid.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
The key study was conducted in line with GLP and Test O.1 of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, 5th revised edition 2009 and Section 2.14 of Regulation (EC) No 1272/2008 of 16 December 2008 on Classification Labelling and Packaging of Substances and Mixtures. It was assigned a reliability score of 1 in accordance with the criteria detailed by Klimisch (1997).
The burning time of test material/cellulose mixtures (4:1 and 1:1 ratio by mass) were compared with the burning time of potassium bromate/cellulose mixtures (3:7 ratio by mass). The mean burning times obtained for the mixtures of test material and cellulose were greater than the mean burning time of potassium bromate/cellulose mixtures (3:7 ratio by mass).
Under the conditions of this study, the test material has been determined not to be an oxidising solid.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation 1272/2008, the test material does not require classification for oxidising properties.
