Overview

CEN ISO/TS 19392-3:2022 (adoption of ISO/TS 19392-3:2018) specifies laboratory test methods for assessing the resistance of coating systems and tapes on wind‑turbine rotor blades to rain erosion using a controlled water jet test. The document describes how to simulate rain impacts with defined water‑jet geometry and pressure, and how to detect and evaluate coating damage until the composite substrate is exposed.

Key topics and technical requirements

Scope and purpose: Determination and evaluation of rain erosion resistance for coatings and protective tapes used on rotor blades.

Test principles: Three main exposure methods:

Interrupted/pulsating water jet on a fixed panel (PJET).
Continuous water jet on a slowly moving panel with a vertical rotation axis.
Continuous water jet on a slowly moving panel with a horizontal rotation axis.

End point and evaluation: Test proceeds until coating defects uncover the substrate; damage is detected visually or microscopically. Results support pass/fail decisions and comparative ranking of systems.

Test setup and procedure elements (documented in dedicated clauses):

Apparatus, sampling, test‑panel substrate and preparation, conditioning, coating thickness measurement.
Calibration of equipment and defined exposure procedures (number of determinations, interrupted vs continuous jets).
Pre‑ and post‑exposure examination, documentation and test reporting.

Normative references and related test methods: The specification cites ISO standards for sampling, film thickness, visual assessment and coating degradation evaluation (for example ISO 291, ISO 2808, ISO 4628 series) and references ASTM G73 for liquid impingement erosion.

Practical applications

Qualification and comparison of coating systems for new rotor‑blade designs.

Quality control during production to verify rain‑erosion resistance against specified requirements.

R&D and product development to optimize formulations and multilayer systems for erosion resistance.

Failure analysis and maintenance planning by reproducing erosion modes observed in service.

Procurement and certification: specifying test methods in tenders and conformity assessments for wind‑turbine components.
