The concentration of the test item in water was 0.1 %. Double distilled
water was used for preparing the solution. The temperature of the
solution at the time of the test was 20 °C. Time of tempering was 20
minutes. The calculation of the surface tension was done under
consideration of the correction of the test equipment and according to
Zuidema and Waters by the measuring device.
The test was performed as stipulated in EC Test Procedure A.5 'Surface
Tension' and DIN EN 14370 'Surface active agents - determination of
The ring method was used to determine the surface tension. In this test
the force is measured which is necessary to draw a horizontal ring,
which is horizontal suspended from the surface of liquid. The surface
tension is then calculated.
Bayscript Gelbkomponente shows a surface tension of 66.4 mN/m.
