- other: Short summary of results
- Qualifier:
- equivalent or similar to guideline
- Version / remarks:
- Wilhelmy Plate method
- Principles of method if other than guideline:
- The surface tension of a liquid is determined according to the plate method using a K20 of KRUSS. A platinum (Pt) plate is dipped into a vessel containing the liquid sample. Pt is used in order to achieve perfect wetting of the plate by the liquid. When a vertically suspended plate touches a liquid surface or interface, then a force F, which correlates with the surface tension or interfacial tension σ and with the contact angle θ according to the following equation, acts on this plate: σ = F/(L*cos θ). The wetted length L of the plate is equal to its perimeter. To measure the force F, the plate is attached to a force sensor of a tensiometer. For reliable measurements, the viscosity of the liquids should be lower than 10000cps, and this method can be only used when the products have flowability. The results are reported at 25°C.
