The method to calculate the surface tension component is defined in ISO 19403-5:2017 standard.
Surface tension can be measured with force tensiometer using Du Noüy ring or Wilhelmy plate. Or with optical tensiometer using the pendant drop method.
Du Noüy method utilizes the interaction of a platinum ring with the surface of the liquid.
Surface tension of blood is an important characteristic when protective materials are being evaluated.
A basic requirement of any coating is that it should form a uniform, defect-free surface. Surface and interfacial tensions play a key role in that.
Surfactants are used in many industrial fields. Characterization of surfactants is thus important to optimize their performance and the products they are applied to. Surface and interfacial tension measurements offer versatile method to study the properties and behavior of the surfactant solution.
