適用范圍：This part of ISO/TS 21268 specifies a test providing information on leaching of soil and soil materials underthe experimental conditions specified hereafter, and particularly at a liquid to solid ratio of 2 l/kg dry matter. Itapplies to soil and soil material with a particle size less than or equal to 4 mm.This part of ISO/TS 21268 has been developed to measure the release of inorganic and organic constituentsfrom soil and soil material and the ecotoxicological effects of eluates with respect to micro-organisms, faunaand flora. The test is not suitable for constituents that are volatile under ambient conditions. Forecotoxicological testing, see ISO 15799.NOTE 1 Volatile organic constituents include the low-molecular-weight components in mixtures such as mineral oil.NOTE 2 It is not always possible to optimise test conditions simultaneously for inorganic and organic constituents andoptimum test conditions may also vary between different groups of organic constituents. Test requirements for organicconstituents are generally more stringent than those for inorganic constituents. The test conditions suitable for measuringthe release of organic constituents will generally also be applicable to inorganic constituents.NOTE 3 For ecotoxicological testing, eluates representing the release of both inorganic and organic contaminants areneeded. In this document, ecotoxicological testing is also meant to include genotoxicological testing.The test procedure specified in this part of ISO/TS 21268 produces eluates, which are subsequentlycharacterised 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 todescribe all leaching properties of a soil. Additional leaching tests are needed for that extended goal. This partof ISO/TS 21268 does not address issues related to health and safety. It only determines the leachingproperties as outlined in Clause 4.
