GB/T 14216-2008 "Plastics - Film and sheeting - Determination of wetting tension" specifies the method for determining the surface wetting tension of plastic films and sheets. The standard method is the liquid application method, which involves drawing a line on the plastic surface using a series of test liquids with known surface tensions and observing whether the liquid film breaks within a specified time (usually 2 seconds) to determine and characterize the wettability of the plastic surface.
