ISO 304 Surfactants - Determination of Surface Tension by Drawing Liquid Films

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 304 testing. This international standard specifies a test method for the determination of the surface tension of aqueous or organic solutions of surfactants and mixtures containing one or more surfactants by forming liquid films.

ISO 304 Surfactants - Determination of Surface Tension by Drawing Liquid Films

It also applies to the measurement of surface tension of pure liquids or solutions other than those mentioned above. Surface tension is a fundamental property of liquids in general and aqueous solutions of surfactants in particular.

However, the measurement of this property can be measured in the case of solutions of surfactants, their detergency, wetting, foaming, emulsifying activities, etc. does not allow any assumptions about Indeed, no connection can be made between the surface tension performance characteristics of surfactants and their solutions.

The maximum force required to move vertically on a stirrup or ring in contact with the surface of the liquid being examined is measured on a rimmed plate or placed in a measuring cup to separate it from this surface. The surface tension of pure liquids or other solutions can also be measured by this method.

EUROLAB assists manufacturers with ISO 304 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.
