Endpoint:
flammable solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is completely molten at 160°C
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:

Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

Flammability: non flammable 

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The registered substance is a low melting point solid. The flammability of such substances can be assessed on the basis of flash point.

There is no indication on the basis of structure and experience in handling and use that the substance is pyrophoric (flammable in contact with air) or flammable in contact with water.

Therefore, in accordance with Section 1 of REACH Annex XI, there is no need to conduct further flammability testing.

In a secondary source to which reliability could not be assigned, a lower flammable limit and an upper flammable limit in air of 2.9 (vol%) and 16 (vol%) respectively were reported for the substance.

Justification for classification or non-classification

The substance is not classified for flammability on the basis of the available measured flash point of 99°C at 1013 hPa and boiling point of 206 - 220°C.
