Key result
Flash point:
105 °C
Atm. press.:
1 021 hPa

Preliminary test:

The estimated flash-point of the test substance was 108°C.

Main study:

The results of the main study on the determination of the flash-point of the test substance are given in Table 1 below.

The difference between the results obtained with the two tests was ≤ 6°C. From this, it was concluded that the flash-point of the test substance is the lowest flash-point obtained.

Interpretation of results:
GHS criteria not met
Conclusions:
A measured flash point of 105°C at 1021 hPa was determined for the substance in accordance with EU Method A.9 and in compliance with GLP. The result is considered reliable.

Description of key information

Flash point: 105°C at 1021 hPa (ISO 2719)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
105 °C

Additional information

A measured flash point of 105°C at 1021 hPa was determined for the substance using a closed-cup method in accordance with the ISO 2719 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as key study.

In another secondary source to which reliability could not be assigned, a limit flash point of >93°C was reported for the substance.

A flash point of 105°C at 1021 hPa and predicted boiling point of 300°C at 1013 hPa indicate the substance should not be classified as a flammable liquid according to the criteria of Regulation (EC) No. 1272/2008.
