Conclusion

The flash point of the test item was 60.0 ± 0.5°C (corrected value).

Interpretation of results:

study cannot be used for classification

Remarks:

Further sustained combustibility testing confirmed the substance does not meet GHS criteria for flammable liquids.

Conclusions:

A flash point value of 60.0 ± 0.5°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Flash point: 60°C at 1013 hPa (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:

60 °C

Additional information

A measured flash point of 60.0 ± 0.5°C at 1013 hPa was determined for the submission substance using a rapid equilibrium method in accordance with ISO 3679 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as key study.

In available secondary source to which reliability could not be assigned, a flash point value of 79°C at 1013 hPa was reported for the substance.

Further sustained combustibility testing found that the substance is not considered to support combustion. Therefore, the substance does not meet the criteria for classification as a Flammable liquid and vapour according to the criteria of Regulation (EC) No. 1272/2008.
