ISO/TS 21268-1:2007 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. It applies to soil and soil material with a particle size less than or equal to 4 mm.ISO/TS 21268-1:2007 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. For ecotoxicological testing, see ISO 15799.The test procedure specified in ISO/TS 21268-1:2007 produces eluates, which are subsequently characterised by existing physical, chemical and ecotoxicological standard methods.This procedure is not applicable to materials with a dry-matter-content ratio lower than 33 %.This test is mainly aimed at being used for routine and control purposes, and it cannot be used alone to describe all leaching properties of a soil. Additional leaching tests are needed for that extended goal. ISO/TS 21268-1:2007 does not address issues related to health and safety. It only determines the leaching properties.
