Nanotechnologies — Superhydrophobic surfaces and coatings: characteristics and performance assessment

Scope

This technical specification (TS) specifies the performance assessment method/s for superhydrophobic
surfaces and coatings subjected to mechanical stress, solar radiation and weathering, liquids, and
thermal cycling, where applicable based on the agreement between interested parties. The
performance assessment is carried out based on comparative measurements of the advancing and
receding angles and calculating the contact angle hysteresis before and after the above-mentioned
working/environmental conditions. This document does not address safety and environmental related
issues of such coatings.
Note 1. This TS is applicable to any superhydrophobic surfaces and coatings on which measuring the
advancing and receding angles is possible.
