Overview
SIST-TS CEN ISO/TS 19392-6:2026 specifies a standardized test method to determine and evaluate the adhesion strength of artificial ice on coated substrates using a centrifuge. Focused on paints and varnishes for wind-turbine rotor blades, this technical specification defines basic ice types, outlines test sample preparation, and establishes parameters for reproducible ice adhesion measurement. It supports performance validation of icephobic coatings under simulated operational conditions. While the method aims to standardize procedure, it does not prescribe fixed parameters to encompass all real-world icing scenarios on wind turbines.
Key Topics
- Ice adhesion measurement: The core of the standard is the use of a centrifuge to quantify the force needed to detach artificial ice from test panels coated with candidate rotor blade coatings.
- Ice types:
- Static ice: Created from liquid water without dynamic effects.
- Impact ice: Produced by exposing the test surface to supercooled water droplets at high velocity in an ice wind tunnel.
- Test reproducibility: Specifies critical parameters such as temperature, ice mass, iced area, and centrifuge acceleration to ensure consistent, comparable results.
- Substrate and coating preparation: Recommends the use of flat panels (e.g., glass fiber composites or aluminium), proper coating application, and conditioning protocols to replicate field conditions.
- Failure mode analysis: Distinguishes between adhesive (clean detachment) and cohesive (residual ice) failure to provide both quantitative and qualitative evaluation of coating performance.
Applications
- Rotor blade coatings evaluation: Essential for manufacturers, researchers, and quality assurance teams assessing the icephobic performance of paints and varnishes under controlled laboratory conditions.
- Wind turbine maintenance optimization: By simulating operational ice loads, the test method helps optimize coatings that reduce ice buildup, mitigating energy losses, maintenance costs, and safety risks associated with ice shedding.
- Product development and certification: Assists coating developers in benchmarking new materials and supports certification efforts where standardized de-icing characteristics are required.
- Research and innovation: Facilitates R&D into improved materials and techniques for ice mitigation on wind turbines, promoting efficiency and reliability in cold climate wind power installations.
