0.25 vol%

Conclusions:

The surface tension of FAT 40034/F was determined to be 62.889 mN/m.

Executive summary:

The determination of the surface tension of the test item was based on OECD Guideline 115 and EU Method A.5. It was accomplished by means of a Tensiometer, using the Wilhelmy plate method. The surface tension of FAT 40034/F was determined to be 62.889 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.005394 mN/m.
