FP measured = 142.5°C

FP corrected = 142.5+ 0.025 (1013-1015.6) = 142.4°C

The lowest flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5 °C: 142.0 °C.
Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
The flash point of the test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore the test substance is NOT classified as a flammable liquid.
Executive summary:

The flash point of the test substance was determined under GLP according to EU guideline A.9, using a closed cup equilibrium method.

The lowest measured value was corrected to normal atmP.

The normal flash point was 142.0°C (under 1013 hPa).

Description of key information

The substance is NOT classified as a flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
142 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU guideline (equilibrium closed cup method) and under GLP, is available. It is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties. (see IU Section 4.13 endpoint summary for justification of non-classification)
