However since such high temperatures are not found under normal circumstances of transportation and use, thus test chemical was considered non-flammable for chemical safety assessment.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

Oxidising properties:

The study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
