EN 11507 Standard Test for Paints and Varnishes, Exposure of Coatings to Artificial Weathering, Exposure to Fluorescent UV Lamps and Water

EUROLAB laboratory provides testing and compliance services within the scope of EN 11507 standard. EN 11507 specifies exposure conditions for paint coatings exposed to artificial weathering in apparatus including fluorescent UV lamps and condensation or water spray.

The effects of weathering are evaluated individually by comparative tests of the selected parameters.

Due to the absence of visible and infrared energy in the light from such UV lamps compared to sunlight, the test pieces are not heated above the ambient air temperature as they would be in practical use.

Coatings made of paints, varnishes and similar materials are etched in the laboratory to simulate the aging processes that occur during natural weathering. In general, valid correlations between aging during artificial and natural weathering cannot be expected due to the large number of influencing factors.

Some relationships can only be expected if the influence of important parameters (spectral distribution of radiation in their photochemically relevant ranges, temperature of the sample, type of wetting, relative humidity of the wetting cycle) on the coating is known. However, unlike natural weathering, tests in the laboratory are performed taking into account a limited number of variables that can be controlled, so results are more reproducible.

EUROLAB assists manufacturers with EN 11507 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
