CEN/TC 139
| Projekta Nr. | LVS EN ISO 19403-4:2020 |
|---|---|
| Nosaukums | The standard series IS ISO 19403 specifies optical test methods — for the measurement of the contact angle, — for the determination of the free surface energy of a solid surface including the polar and dispersive fractions, — for the determination of the surface tension of liquids including the polar and dispersive fractions, — for the checking of the measurement arrangement with reference materials. It can be applied for the characterization of substrates, coatings, and coating materials. Part 4 of the standard specifies a test method to determine the polar and dispersive fraction of the surface tension of liquids with optical methods. The method can be applied for the characterization of liquid coating materials, especially when drying effects occur during measurement. |
