Scope

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.
