Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1 August 2012 to 23 August 2012
- 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)
- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- other: 2:1 test material to cellulose
- Parameter:
- preliminary test
- Remarks on result:
- vigorous reaction in the preliminary test
- Remarks:
- The cone immediately ignited and flared with a bright orange flame. The cone fully combusted within 2 seconds leaving a black fluffy residue.
- Interpretation of results:
- other: Classified as an oxidiser in accordance with EU criteria
- Conclusions:
- The test material was determined to have oxidising properties.
- Executive summary:
The oxidising properties of the test material were investigated in a GLP study which was conducted in accordance with the standardised guideline EU Method A.17. Powdered test material and cellulose were mixed in a 2:1 ratio and formed into a cone (approximately 3.5 cm diameter at the base and 2.5 cm high) on a non-porous, non-combustible board. The cone was ignited with an air-rich Bunsen burner flame and the mode, vigour and duration of the reaction recorded.
The cone immediately ignited and flared with a bright orange flame. The cone fully combusted within 2 seconds leaving a black fluffy residue. The test material was determined to have oxidising properties.

Additional information
The oxidising properties of the test material were investigated in a GLP study which was conducted in accordance with the standardised guideline EU Method A.17. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality detailed by Klimisch et al (1997).
Powdered test material and cellulose were mixed in a 2:1 ratio and formed into a cone (approximately 3.5 cm diameter at the base and 2.5 cm high) on a non-porous, non-combustible board. The cone was ignited with an air-rich Bunsen burner flame and the mode, vigour and duration of the reaction recorded.
The cone immediately ignited and flared with a bright orange flame. The cone fully combusted within 2 seconds leaving a black fluffy residue. The test material was determined to have oxidising properties.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material requires classification for oxidising properties as Category 1 (H271; May cause fire or explosion, strong oxidiser).
