The method indicates the relative ease of printability/adherability of poly-olefin films and coated surfaces by the measurement of wetting tension.
This method is written to improve the precision of wetting tension measure-ments by eliminating sources of error due to reagent contamination, amount of reagent application, chemical varia-tions in cotton swabs, and the subjective interpretations of T 698.
Because variables other than surface tension are involved, this procedure should not be used to establish absolute limits for printability or adherability between laboratories. Its use is to set quality specification limits, with prior specific agreement between individual parties.
