- no
- GLP compliance:
- no
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- 0.081 other: mm/s (migrated information)

Description of key information
The substance is not an oxidiser, EU Method A.17, Atwal &Tremain (2009)
Key value for chemical safety assessment
- Oxidising properties:
- no
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.17.
Under the conditions of the study the test material was determined not to have oxidising properties as the test material/cellulose mixtures failed to propagate combustion at a rate greater than or equal to that of the barium nitrate/cellulose mixtures.
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 as an oxidiser.
