Atmospheric pressure: 95.9 kPa

Corrected flash point: 142.2 °C

accuracy ± 2 °C

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
Despite the test substance is solid a ambient temperature, this study is relevant for classification purpose, as the melting point is below the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria), therefore the substance is liquid in this range.
As the test result is above these criteria, the substance is NOT classified as a flammable liquid in the two systems.
Executive summary:

The flash point of the test substance was determined under GLP according to ISO3279 (listed in EU A.9 guideline), using a closed cup equilibrium method.

The flash point of test substance has been determined to be 142 ± 2 °C at normal atmospheric pressure.

Description of key information

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

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 EC method (closed cup), is available. It is considered as a key study, and the result is retained as key data.

Despite the substance is solid at ambient temperature, this study is relevant for the classification regarding flammable properties, as low melting point leads to liquid state below the classification temperature criteria:

The result is above the thresholds of Regulation (EC) 1272/2008 (CLP) and UN Globally Harmonised System (GHS), respectively 60°C and 93°C, therefore the test substance is NOT classified as flammable liquid in the two systems.
