Introduction
Ice accretion on rotor blade surfaces of wind turbines can decrease the efficiency and limit the performance
of wind turbines in cold, humid environments. Ice formation can also lead to damage of the rotor blade and
can be hazardous, if ice falls off the blade. Icephobic coatings (“icephobics”) can be applied to rotor blade
surfaces to reduce or prevent the adhesion of ice by removing ice prior to reaching a critical ice mass for the
rotor blades. They can also increase the efficiency of thermal ice protection systems.

Paints and varnishes — Coating systems for wind-turbine

Part 6:
Determination and evaluation of ice adhesion using
centrifuge
1 Scope
This document specifies a method to measure ice adhesion from artificial ice on test substrates by using
a centrifuge. Basic ice types are defined and test parameters for the ice removal are described to achieve
reproducibility of test results for ice adhesion measurements for rotor blade coatings. This document does
not intend to provide fixed test parameter to account for the diversity of relevant icing scenarios in this field
of application.
NOTE In practice, ice adhesion can be determined by two different measurement principles, the centrifugal test
(covered in this document) and the shear test, which differ in dynamic and quasistatic shear rates.
This test method can be used to test the adhesion of dynamic ice on the coating system of a wind turbine
rotor blade under operation.

Introduction

spacing: Exactly 12 pt
Ice accretion on rotor blade surfaces of wind turbines can decrease the efficiency and limit the
performance of wind turbines in cold, humid environments. Ice formation can also lead to damage of
the rotor blade and can be hazardous, if ice falls off the blade. Icephobic coatings (“icephobics”) can be
applied to rotor blade surfaces to reduce or prevent the adhesion of ice by removing ice prior to reaching
a critical ice mass for the rotor blades. They can also increase the efficiency of thermal ice protection
systems.

(covered in this document) and the shear test, which differ in dynamic and quasistatic shear rates. Formatted: std_docTitle, Font: Not Italic, No underline
