Paints and varnishes - Wettability - Part 7 : measurement of the dynamic contact angles and the roll-off angle on a tilt stage
This document specifies a method for the dynamic measurement of the roll-off angle on a tilt stage of a liquid drop on a solid surface. This document also specifies how the dynamic advancing and receding contact angles of the drop rolling off can be determined. The roll-off angle determined through this method can be applied when evaluating easy-to-clean or anti-adherent surfaces.

ISO 19403-7:2017 specifies a method for the dynamic measurement of the roll-off angle of a liquid drop on a solid surface. From the dynamic measurement, the advancing and receding angles of the drop rolling off can also be determined. The roll-off angle plays a role when evaluating, for example, easy-to-clean or anti-adherent surfaces.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
