DIN EN ISO 21268-1:2018-03

DIN EN ISO 21268-1 specifies a test providing information on leaching of soil and soil materials under the experimental conditions specified hereafter, and particularly at a liquid to solid ratio of 2 l/kg dry matter. DIN EN ISO 21268-1 has been developed to measure the release of inorganic and organic constituents from soil and soil material and the ecotoxicological effects of eluates with respect to micro-organisms, fauna and flora. The test is not suitable for constituents that are volatile under ambient conditions. The test procedure specified in DIN EN ISO 21268-1 produces eluates, which are subsequently characterised by existing physical, chemical and ecotoxicological standard methods. This procedure is not applicable to materials with dry matter content lower than 33 %. 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.
