Scope

This document describes a test method that can be used to evaluate the wear of materials and coatings in photovoltaic modules or other photovoltaic devices.
This document is applicable to components on the incident surface (including coatings, front panels, and glass) and the rear surface (including back panels or rear glass). The quantitative correlation between artificial wear and field erosion for specific materials or coatings (depending on factors such as climate, location of use, and application, e.g., use of trackers, mounting on frames, rooftop installation, building integration, or vehicle-mounted photovoltaics) is beyond the scope of this document. The correlation between the attenuation rates of different test methods (linear brush wear, rotating brush wear, sand drop, and high-pressure sandblasting impact) is beyond the scope of this document and may be addressed in reference documents. The correlation between the attenuation rates of unaged and aged samples is beyond the scope of this document and may be addressed in reference documents.
