The lowest flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5 °C: 77.0 °C.

Final results

The flash point of the test item was 77.0 °C under atmospheric conditions (1013 hPa).

Interpretation of results:
Category 4 (combustible liquids) based on GHS criteria
Conclusions:
The corrected flash point of the test item was determined to be 77°C at 101.3 kPa
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 corrected flash point of the test item was determined to be 77°C at 101.3 kPa.

Test item is NOT classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) but it is classified as Flammable liquid category 4 according to UN Globally Harmonised System (GHS).

Description of key information

The flash point of the test item was stated as 77°C.

Test item is NOT classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) but it is classified as Flammable liquid category 4 according to UN Globally Harmonised System (GHS).

 

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:
77 °C

Additional information

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). It is considered as a key study. The result is retained as key data for purpose of CSA.
