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
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:
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: flash point of 45°C to ca. 109°C at 1013 hPa

Key value for chemical safety assessment

Additional information

The flammability of liquids is assessed on the basis of flash point.

There is no indication on the basis of chemical 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.

A Lower Explosion Limit (LEL) of 0.3 - 0.5% and an Upper Explosion Limit (UEL) of >13.5% was determined for the substance using a bomb method in accordance with DIN EN 1839.

In Haas 2012, sustained combustibility study was conducted for the substance in accordance with ISO 9038 test method and in compliance with a known quality system (ISO 9001:2008). Value of >110°C at 1013 hPa was determined for the registered substance. However, no interpretation of the result was indicated in the study report and as such, the result has not been considered further.

Justification for classification or non-classification

Flash point values of 45°C, 82°C, 100°C and approximately 109°C with boiling point of 259.6°C were reported for the registered substance.

The flash point of 45°C indicates that the registered substance should be classified as follows:

Classification and Labelling according to Regulation (EC) No. 1272/2008: Flam. Liq. 3, H226: Flammable Liquid and Vapour

The flash point values of 82°C, 100°C and approximately 109°C indicate that the substance should not be classified for flammability.
