ISO 19403-1:2017 to ISO 19403-7:2017
Paints and varnishes – Wettability
This standard series 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 disperse parts
- for the determination of the surface tension of liquids, including the polar and disperse parts
- for the checking of the measurement arrangement with reference materials.
It can be applied for the characterization of substrates, coatings, and coating materials. The applicability can be restricted for liquids with non-Newtonian rheology.
ISO 19403-1:2017 specifies terms and definitions and defines the general principles.
