- Type of method:
- ring method
- Key result
- Surface tension:
- 70 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- After correction with respect to the table given in the directive A.5. (Harkins-Jordan correction), the final value for the surface tension at 20 °C is:
W = 70.0 mN/m - Executive summary:
The purpose of the test was the determination of the surface tension according to Guideline 92/69/EEC PartA.5. Surface tension using the Ring Method. Study conducted in compliance with GLP.
The method is based on the measurement of the maximum vertical force, which is necessary to separate a ring being in contact with the liquid filled in a measuring cup, from the surface of this liquid.
Instrument: Digital-Tensiometer K10T (Kruss, Hamburg)
After correction with respect to the table given in the directive A.5. (Harkins-Jordan correction), the final value for the surface tension at 20 °C is: W = 70.0 mN/m.
