The lowest flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5 °C: 125.5 °C

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item is therefore 125.5 °C at 1013 hPa
Executive summary:

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a Rapid equilibrium closed cup method (ISO3679, 2015).

The flashpoint of the test item is stated as 125.5°C (298.65 K) at 1013 hPa.

Description of key information

The substance is NOT classified as a Flammable Liquid according to Regulation (EC) N°1272/2008 (CLP criteria).

and UN Globally Harmonized System (GHS criteria).

 

Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
125.5 °C

Additional information

A fully reliable study conducted under GLP according to EU Method A.9 (Flash-Point), using a Rapid-equilibrium closed cup method (ISO3679) is available. It is considered as a key study. The result is retained as key data for purpose of CSA.

This study is relevant for the classification regarding flammable properties.
