In the main test the lowest temperature where an ignition was observed was 137.0 °C.

The mean measured flash point is corrected to the ambient pressure to be 137.22 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 137.0 °C.

 

Final Results

The test item has a flash point of 137.0 °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).

UN Transport Regulation: With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid in class 3 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.

Conclusions:
A flash point value of 137.0 °C (at 1013 hPa) was determined for the test substance according to EU Method A.9.
