This International Standard specifies a method of measuring the contact angle of water droplets on corona-treated polymer film surfaces and subsequently determining the wetting tension of the film.
The method is applicable to practically any polymer film. It is not applicable, however, if the surface of the film exhibits a chemical affinity for water.
