In the main test the lowest temperature where an ignition was observed at ambient pressure was 152.5 °C. The measured flash point is corrected to the normal atmospheric pressure to be 152.50 °C. The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 152.0 °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 Method (listed in EU A.9 guideline) using a closed cup method.

In the main test, the lowest temperature where an ignition was observed at ambient pressure was 152.5 °C. The measured flash point is corrected to the normal atmospheric pressure to be 152.50 °C. The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 152.0 °C.

The flash point of test substance has been determined to be 152.0 °C at 1013 hPa.

Description of key information

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

Key value for chemical safety assessment

Flash point at 101 325 Pa:
152 °C

Additional information

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