ResumoFaçade coatings are exposed to weathering. Driving rain events can cause façade runoff bearing the potential to release substances from the coating. In order to derive reliable and reproducible information about this so-called leaching (emission into water), a laboratory test method has been developed, that has been published as European Standard EN 16105:2011. An interlaboratory comparison has been performed with 8 participants in order to validate the test method. This article describes the test results that reveal statistics on the quality of the test method and allows further insights to the leaching mechanism in coatings.
