EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 19403-1 testing. This standard specifies general terms and definitions for wettability.
A liquid in contact with a solid surface is called wetting. As a result, the liquid forms a typical droplet shape. The characteristic feature of the drop is the angle formed by the tangent on the contour with the solid surface at the three phase points.
The position of the thermodynamic equilibrium state, which causes the static contact angle to occur, depends on the pressure and other thermodynamic state variables as well as the temperature. Because the interface free energy and surface energy are based on different forces between atoms or molecules, it is necessary to take polarity into account to evaluate wettability. The model described below is mainly based on the assumption that polar and diffuse interactions predominate.
EUROLAB assists manufacturers with EN ISO 19403-1 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
