标准范围

ISO/TS 21268-1:2007规定了在下文规定的试验条件下，尤其是在2 l/kg干物质的液固比条件下，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 21268-1:2007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的生态毒理学影响-生物、动植物。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 21268-1:2007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。本程序不适用于干物质含量比低于33%的材料。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 21268-1:2007未涉及与健康和安全相关的问题。它只决定浸出性质。

ISO/TS 21268-1:2007 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.
