Overview

CEN ISO/TS 19392-2:2022 (identical to ISO/TS 19392-2:2018) defines a laboratory test method to determine and evaluate resistance to rain erosion of coating systems and tapes for wind‑turbine rotor blades using a rotating‑arm apparatus. The technique accelerates coated test panels through a simulated rain field; damage is assessed visually or microscopically at intervals until the composite substrate is exposed. The document is a Technical Specification published by CEN for provisional application (June 2022).

Key topics and technical requirements

Scope and purpose: Test method for rain erosion resistance of paints and varnishes applied to wind‑turbine rotor blades (including tapes).

Principle: Coated specimens mounted on a rotating arm pass repeatedly through a controlled rain field; impinging droplets produce progressive erosion.

Apparatus: Rotating‑arm test rig with rain generator and specimen mounts (general arrangement and components described).

Specimen preparation: Substrate selection, coating application, conditioning and film‑thickness control (references to ISO film thickness and sampling standards).

Test procedure: Number of determinations, pre‑exposure examination, calibration of rig, exposure intervals, and criteria for test termination (test ends when substrate is exposed).

Evaluation: Visual and microscopic inspection methods, damage assessment and pass/fail or comparative ranking of coating systems.

Precision and reporting: Requirements for test reporting and precision statements; normative references underpinning test consistency.

Normative references: Includes related ISO methods (e.g., ISO 291, ISO 2808, ISO 4618, ISO 4628 series, ISO 13076) and ASTM G73-10 as related background.

Applications and who uses it

This Technical Specification is intended for:

Coating manufacturers developing and validating wind‑turbine blade paints and protective tapes.

Wind‑turbine OEMs and blade fabricators specifying coatings for durability and warranties.

Independent testing laboratories performing comparative rain‑erosion tests and quality control.

R&D and materials engineers investigating erosion mechanisms and improving formulations.

Procurement and certification bodies using standardized test results for supplier evaluation and acceptance criteria.

Practical uses include product development, comparative benchmarking of coating systems, quality assurance of production batches, and failure analysis of blade surface degradation.
