Description of key information
Based on a GLP study according to UN O.1 (K1, Ciric, 2017), T001202 is considered not to have oxidising properties. T001202 can be concluded to be incapable of causing fire or enhancing the risk of fire when in contact with combustible material.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
T001202 does not need to be classified as an oxidising substance since the mean burning time of the test item mixtures was higher than the mean burning time of the reference mixure.
