Deviations:
no
Qualifier:
according to guideline
Guideline:
other: DIN EN 14370
Deviations:
no
Principles of method if other than guideline:
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.
GLP compliance:
yes

Storage: Room temperature
Expiration date: 2017-10-10
Surface tension:
66.4 mN/m
Temp.:
20 °C
Conc.:
0.1 other: %

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.

Results:

   Surface Tension (mN/m)
  Value 1  66.47
  Value 2  66.42
  Value 3  66.40
  Value 4  66.37
  Value 5  66.36
  Mean value  66.40
 Standard deviation  0.04
  Test time  83 s
Conclusions:
Bayscript Gelbkomponente shows a surface tension of 66.4 mN/m.
Executive summary:
