Paints and varnishes - Wettability - Part 6: Measurement of dynamic advancing and receding angle by changing the volume of a drop (ISO 19403‑6:2024)

This document specifies a method to measure the dynamic contact angle with an optical method. The dynamic advancing and the dynamic receding contact angles are determined. By using the measurement specified in this document, the wetting and dewetting properties can be characterized. The morphological and chemical homogeneity of interfaces can also be determined.
