Measured flash point = 122°C; accuracy ± 2 °C

Atmospheric pressure = 102.19 kPa

Corrected flash point = 122 °C

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
The flash point of test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore, test substance is not a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was determined under GLP according to ISO 3679 (listed in EU Method A.9), using a closed cup equilibrium method.

 

The flash point of test substance has been determined to be 122 ± 2 °C, corrected to normal atmP.

Description of key information

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

Key value for chemical safety assessment

Flash point at 101 325 Pa:
122 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EC method (closed cup), 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.
