Paints and varnishes - Coating systems for wind-turbine rotor blades - Part 5: Measurement of transmittance properties of UV protective coatings (ISO/TS 19392-5:2023)
This document specifies a test method to measure the ultraviolet (UV) and visible (VIS) spectral transmittance in the wavelength range from 280 nm to 700 nm of coatings for wind turbine rotor blades. Single and multilayer coatings or coating systems can be tested.
From the spectral transmittance the transmittance of UV, VIS and the combined UV and VIS wavelength range can be calculated.
It is applicable to free coatings films or coatings applied on a UV-transparent quartz substrate.
Beschichtungsstoffe - Beschichtungssysteme für Rotorblätter von Windenergieanlagen - Teil 5: Messung der Transmissionseigenschaften von UV-Schutzbeschichtungen (ISO/TS 19392-5:2023)
Dieses Dokument legt ein Prüfverfahren zum Messen des ultravioletten (UV) und sichtbaren (VIS) spektralen Transmissionsgrades im Wellenlängenbereich von 280 nm bis 700 nm von Beschichtungen für Rotorblätter von Windenergieanlagen fest. Es können ein- und mehrschichtige Beschichtungen oder Beschichtungssysteme geprüft werden.
Aus dem spektralen Transmissionsgrad kann der Transmissionsgrad für UV, VIS und den kombinierten UV- und VIS-Wellenlängenbereich berechnet werden.
Es ist anwendbar auf freie Beschichtungsfilme oder auf Beschichtungen, die auf einem UV-transparenten Quarzsubstrat aufgebracht sind.

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).

Introduction
In the wind energy industry, coatings are applied to rotor blades surface to protect the glass fibre
reinforced polymer composite substrate from environmental stresses. Rain drops and hailstones can
damage these coatings in such a way that individual layers come off or the whole coating delaminates
from the substrate. This applies mostly to the leading edge. Glass fibre reinforced polymer composites
and other blade materials can be also sensitive to UV degradation and thus can be damaged during
outdoor operation, if not protected accurately against irradiation by solar radiation. Failure of
protection can lead to delamination and a subsequent failure of the full blade.
An important function of the rotor blade coating is therefore to protect the blade material from UV
radiation. This applies to the leading edge, but also to the other surface areas of the blade.
The damage by solar radiation is mainly induced by the most energetic ultraviolet (UV) radiation, but
also visible (VIS) radiation (e.g. violet or blue radiation) is still
