Description of key information
The test substance has not oxidising properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
EU method A.17 - preleminary study.
In this preliminary test, the reference mixture burned with a flame, emitting a white smoke. The burning time was approximately 41 s. The test substance/cellulose pile burned but went out once the flame of the gas burner was removed. From this, it was concluded that the substance reacts less vigorously than the reference mixture.
Justification for classification or non-classification
No classification of the substance as to its oxidising properties.
