Tested according to ASTM international G73-10.
PolyTech is testing according to the ASTM G73-10 standard, which is the most widely used industry standard at the moment. The rain erosion test is widely accepted as being the most suitable test for evaluating anti-erosive properties of coatings on the leading edge of wind turbine blades.
The ASTM G73-10 and the ISO 17025 accreditation verifies the stability and repeatability of the test to ensure that the tests made are 100% comparable. A reference test is performed every 4 weeks.
