In the main test the lowest temperature where an ignition was observed was 56.0 °C.

The average measured flash point is corrected to the ambient pressure to be 56.71 °C

The resulting average corrected flash point rounded down to the nearest multiple of 56.5 °C.

 

Final Results

The test item has a flash point of 144.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) according to Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 2719 (2003)

Conclusions:
A flash point value of 56.5 °C (at 1004.6 hPa) was determined for the test substance according to EU Method A.9.

Description of key information

Flash point: 56.5 °C at 1004.6 hPa (E.U. Method A.9.). The test item has to be classified as flammable liquid of category 3.

Key value for chemical safety assessment

Additional information

A flash point value of 56.5 °C (at 1004.6 hPa) was determined for the test substance according to E.U. Method A.9.
