Plastics -- Film and sheeting -- Measurement of water-contact angle of corona-treated films
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
ISO 15989:2004 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.
