This document specifies general terms and definitions for wettability. Some general principles are described in Annex A. This document is intended to be used in conjunction with ISO 4618.
Abstract
Overview
ISO 19403-1:2022 - Paints and varnishes - Wettability - Part 1: Vocabulary and general principles - defines the terminology and fundamental concepts used for wettability assessment of coatings, substrates and liquids. The standard establishes general terms and definitions for contact angles, surface free energy, surface tension, three‑phase points and related concepts, and provides informative general principles (Annex A) for interpreting contact‑angle and surface‑energy measurements. ISO 19403-1 is intended to be used in conjunction with ISO 4618 and other parts of the ISO 19403 series that specify test methods.
Key topics and technical requirements
- Vocabulary and definitions: precise terms for contact angle, base line, three‑phase point, pendant drop, fit error, shape parameter (B), interfacial energy and more.
- Surface energy concepts: distinction between surface free energy of solids and surface tension of liquids, including polar and dispersive (non‑polar) fractions.
- Wetting classifications: definitions for hydrophobic (>90° contact angle), hydrophilic (<90°), superhydrophobic (>150° with contact angle hysteresis
