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))

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.

Description of key information

The substance was determined to have oxidising properties

Key value for chemical safety assessment

Oxidising properties:
yes

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).
