标准范围

ISO/TS 21268-4:2007规定了获取材料短期和长期浸出行为及特性信息的试验方法。它适用于测定pH值对土壤和土壤材料中无机和有机成分可滤性的影响，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。ISO/TS 21268-4:2007中规定的试验程序产生的洗脱液随后通过物理、化学和生态毒理学标准方法进行表征。

ISO/TS 21268-4:2007 specifies a test method to obtain information on the short- and long-term leaching behaviour and characteristic properties of materials. It applies to the determination of the influence of pH on the leachability of inorganic and organic constituents from soil and soil material, and the ecotoxicological effects of eluates with respect to microorganisms, fauna and flora. The test is not suitable for constituents that are volatile under ambient conditions.The test procedure specified in ISO/TS 21268-4:2007 produces eluates that are subsequently characterized by physical, chemical and ecotoxicological standard methods.
