Tiivistelmä: Proftest SYKE carried out the proficiency test (PT) in cooperation with the KVVY Tutkimus Oy for the laboratories conducting leaching tests for solid waste samples in spring 2021. The results of the up-flow percolation test (EN 14405:2017) for samples of bottom ash from biofuel combustion were compared and evaluated. In total, there were 7 participants in the PT. For all the measurands which were evaluated, the median or the mean of the reported results was used as the assigned value. The overall performance of the participants was evaluated by using En scores and 72 % of the evaluated results were satisfactory. The participant results were also evaluated by means of D% scores and 51 % of those were ≤ |25 %|. The pH results were evaluated by means of z scores and 82 % of results were satisfactory. Warm thanks to all participants in this proficiency test!
