dc.description.abstract Proftest SYKE carried out the proficiency test in cooperation with KVVY Tutkimus Oy for the laboratories conducting leaching tests for solid waste material in November-December 2018. The results of the one stage batch leaching test (EN 12457-2) for foundry sand samples were compared and evaluated. The tested measurands were metals (As, Ba, Cd, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Se, V, Zn), Cl-, SO4 2-, F-, DOC, pH, and conductivity. In total, 10 participants joined in the proficiency test. In this PT for all the evaluated measurands the median of the results reported by the participants was used as the assigned value. The measurands Ba, conductivity, DOC, Ni, pH, SO4, and Zn were evaluated with z scores and of those results 92 % were satisfactory, when deviation of 0.3 pH units and 20–30 % for other measurands was accepted from the assigned value. Further, measurands As, Cr, Cu, and V were evaluated with En scores and 76 % of the results were satisfactory. Warm thanks to all participants in this proficiency test! fi
