适用范围

DIN ISO/TS 21268-4 specifies a test method to obtain information on the short- and long-term leaching behaviour and characteristic properties of materials. It applies to the determination of the influence of pH on the leachability of inorganic and organic constituents from soil and soil material and the ecotoxicological effects of eluates with respect to microorganisms, fauna and flora. The test is not suitable for constituents that are volatile under ambient conditions. Equilibrium condition, as defined in DIN ISO/TS 21268-4, is established by the addition of pre-determined amounts of acid or base to reach desired end pH values. The test procedure specified in DIN ISO/TS 21268-4 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.
