Flash

 

Atmospheric pressure: 97.4 kPa

Corrected flash point: 154.9 °C

 

The flash point of the test material has been determined to be 155 ± 2 °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 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 ISO 3679 (listed in EU A9 guideline), using closed cup equilibrium method. The main test was performed in duplicate, and the mean result was retained, and corrected to normal atmospheric pressure:

Observed flash point: 154°C

Atmospheric pressure: 97.4 kPa

Corrected flash point: 154.9 °C

 

The flash point of the test substance has been determined to be 155 ± 2 °C.

Description of key information

The substance is NOT classified as a flammable liquid according to CLP and GHS criteria. 

Key value for chemical safety assessment

Flash point at 101 325 Pa:
155 °C

Additional information

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

This study is relevant for the classification regarding flammable properties.
