Evaluation and Result

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 80.0 +- 0.5 °C (corresponding to 353.2 +- 0.5 K).

Interpretation of results:
other: No classification according to CLP criteria
Conclusions:
The flash point of the test item was determined according to EU A.9. and found to be 80 °C at 1013 hPa.
Executive summary:

The flash point of the test item was determined according to EU A.9. and found to be 80 °C at 1013 hPa.

Description of key information
