DIN SPEC 1129-2010 土质.土壤和土壤材料的连续化学和毒物学测试的浸出过程.第2部分:液固比为101/kg干物质的批量试验(ISO/TS 21268-2-2007).德文版本CEN ISO/TS 21268-2-2009
Soil quality - Leaching procedures for subsequent chemical and ecotoxicological testing of soil and soil materials - Part 2: Batch test using a liquid to solid ratio of 10 l/kg dry matter (ISO/TS 21268-2:2007); German version CEN ISO/TS 21268-2:2009
DIN ISO/TS 21268-2 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 10 l/kg dry matter. It applies to soil and soil material with a particle size less than or equal to 4 mm. DIN ISO/TS 21268-2 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 ISO/TS 21268-2 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.
