ISO/TC 35/SC 9/WG 32 - Coating materials for wind-turbine rotor blades

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.

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.

This document specifies a test method for the determination of resistance of coating systems or tape for wind-turbine rotor blades to rain erosion by using the rotating arm test.

This document specifies test methods for the determination of resistance of coating systems or tape for wind-turbine rotor blades to rain erosion by using the water jet test.

This document specifies minimum requirements and weathering for coating systems for wind-turbine rotor blades.
