Paints and varnishes — Coating systems for wind-turbine rotor blades — Part 6: Determination and evaluation of ice adhesion using centrifuge

This document describes 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

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.
