Erosion test - Maximize service life of your wind turbine blades
Polytech has two accredited test centers. At our center in Bramming, Denmark, we perform erosion tests on wind turbine blades in accordance with the recommended practice: DNV-RP-0171.

Wind turbine blades are continuously exposed to UV rays from the sun, as well as to a constant barrage of rain drops, grains of sand, dust particles, hail, insects and more. The protective properties of the surface are therefore crucial to the service life of the blade – especially on the leading edge, which bears the brunt of the impacts.
It is essential to choose the best possible surface so as to maximise service life, fulfil warranty obligations and control costs.
Polytech has two accredited test centers in Denmark. At our center in Bramming, we perform erosion tests on wind turbine blades in accordance with the latest recommended practice: DNV-RP-0171.
The test is designed to establish the durability of the protective layer on the leading edge.
It is possible to combine the erosion test with an accelerated weathering test, such as ISO 20340 (Simulation of impacts in offshore environment).
We calibrate our test equipment in accordance with DNVGL-RP-0171 whenever critical parameters are changed, as well as at fixed, predefined intervals.
The pictures from an erosion test can be converted into a graph by measuring the development of the erosion (mm) in each interval and plotting them in. On comparison of several tests, the leading edge protection with the shallowest slope will be the most resistant to erosion.
Two valid parameters for the development of erosion are:
Independent third-party tests
The Polytech Test Center is accredited by DANAK in accordance with the ISO 17025 standard and operates as an independent test institute.
