标准范围

ISO/TS 21268-2:2007规定了在下文规定的实验条件下，尤其是在10 l/kg干物质的液固比下，提供土壤和土壤材料浸出信息的试验。适用于土壤和粒径小于或等于4mm的土壤材料。ISO/TS 21268-2:2007旨在测量土壤和土壤材料中无机和有机成分的释放，以及淋洗液对微生物、动植物的生态毒理学影响。该试验不适用于在环境条件下易挥发的成分。有关生态毒理学测试，请参见ISO 15799。ISO/TS 21268-2:2007中规定的试验程序产生洗脱液，随后通过现有的物理、化学和生态毒理学标准方法对其进行表征。该测试主要用于常规和控制目的，不能单独用于描述土壤的所有淋滤特性。为了实现这一扩展目标，还需要进行额外的浸出试验。ISO/TS 21268-2:2007未涉及与健康和安全相关的问题。它只决定浸出性质。

ISO/TS 21268-2:2007 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 10 l/kg dry matter. It applies to soil and soil material with a particle size less than or equal to 4 mm.ISO/TS 21268-2:2007 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 21268-2:2007 produces eluates, which are subsequently characterised by existing physical, chemical and ecotoxicological standard methods.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 21268-2:2007 does not address issues related to health and safety. It only determines the leaching properties.
