DIN SPEC 1130:2010 PDF

Scope: DIN ISO/TS 21268-3 specifies a test, which is aimed at determining the leaching behaviour of inorganic and organic constituents from a soil and soil material. The method is a once-through percolation test with water (0,001 mol/L CaCl2) under standardised conditions of flow rate. The material is leached under dynamic hydraulic conditions. The eluates obtained can be used to determine the ecological properties of the soil with respect to micro-organisms, flora and fauna. 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. The test procedure specified in DIN ISO/TS 21268-3 produces eluates, which are subsequently characterised by existing physical, chemical and ecotoxicological standard methods. This test is mainly aimed at use for routine and control purposes, and alone it cannot be used to describe all leaching properties of a soil. Additional leaching tests are needed for that extended goal.
