Soil quality. Leaching procedures for subsequent chemical and ecotoxicological testing of soil and soil-like materials - Up-flow percolation test1 Scope This document specifies a test, which is aimed at determining the leaching behaviour of inorganic and organic substances from a soil and soil like materials. The method is a once through up flow percolation test under standardized conditions of flow rate. The material is leached under dynamic hydraulic conditions. The document has been developed to measure the release of inorganic and organic substances from soil and soil like material as well
