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 as to produce eluates for subsequent ecotoxicological testing. For ecotoxicological testing, see ISO 15799[6]and ISO 17616[7]. The test results enable the distinction between different release patterns, for instance wash-out and release under the influence of interaction with the matrix, when approaching local equilibrium between material and leachant. This test method produces eluates, which can subsequently be characterized by physical, chemical and ecotoxicological methods in accordance with existing standard methods. The results of eluate analysis are presented as a function of the liquid/solid (L/S) ratio. The test is not suitable for substances that are volatile under ambient conditions.Cross References:ISO 10523ISO 3696ISO 7027-1ISO 11465ISO 5725-1:1994ISO 5667-3:2018ISO 5725-2:1994ISO 18400-101ISO 18400-202ISO 11464ISO 18400-105ISO 18400-104ISO 15799DIN 19528EN 12920ISO 23909ISO 17616ISO 18772CEN/TS 14405:2004All current amendments available at time of purchase are included with the purchase of this document.
