Reference

Reference 1

Endpoint:

flammable liquids: obsolete as covered by section 'Flash point'

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Reference 3

Endpoint:

pyrophoric liquids

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 flammability of liquids is 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 Section1 of REACH Annex XI, there is no need to conduct further flammability testing.

In a reliable study, a Lower and an Upper explosion limits of 0.7% and approximately >13.6% at 200°C and 1 bar respectively were obtained for the substance using DIN EN 1839 test method. In a secondary source to which reliability could not be assigned, a Lower explosion limit of 0.43 at 157°C was reported for the substance using DIN 51649 test method.

Justification for classification or non-classification

The substance is not classified for flammability as it has a flash point of 136°C.
