本文件规定了一项测试，该测试提供了在下文规定的实验条件下，特别是在10L/kg干物质的液固比下，土壤和土壤材料的浸出信息。 该文件旨在测量土壤和类土壤材料中无机和有机物质的释放，并产生用于后续生态毒理学测试的洗脱液。生态毒理学试验见ISO 15799[6]和ISO 17616[7]。 注1挥发性有机物包括矿物油等混合物中的低分子量物质。 注2:同时优化无机和有机物质的测试条件并不总是可能的，不同有机物质组之间的最佳测试条件也可能不同。有机物的测试要求一般比无机物严格。适用于测量有机物释放的测试条件通常也适用于无机物。 注3:在有机物质类别中，极性较大、相对水溶性的化合物与非极性、疏水性有机物质之间的行为存在显著差异。在后一种情况下，释放机制（例如颗粒结合或溶解的有机碳结合）以及可溶性HOCs在它们接触的不同材料（例如瓶子、过滤器）上的吸附损失可能更为关键。只有在充分考虑相关物质的具体性质和相关潜在问题的情况下，才能将测试和结果用于有机物质的浸出。 注4对于生态毒理学试验，需要代表无机和有机物质释放的洗脱液。在本文件中，生态毒理学试验还包括遗传毒理学试验。 该测试方法产生洗脱液，随后可以根据现有标准方法通过物理、化学和生态毒理学方法对其进行表征。该测试不适用于在环境条件下挥发性的物质。 本规程不适用于干物质含量比低于33%的物料。 该测试主要旨在用于常规和控制目的，不能单独用于描述土壤的所有淋溶特性。为了实现这一扩展目标，需要进行额外的浸出测试。本文件不涉及与健康和安全相关的问题。它仅确定第4条中概述的浸出特性。

This document 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. The document has been developed to measure the release of inorganic and organic substances from soil and soil-like material as well as to produce eluates for subsequent ecotoxicological testing. For ecotoxicological testing, see ISO 15799^[6] and ISO 17616^[7]. NOTE 1 Volatile organic substances include the low-molecular-weight substances in mixtures such as mineral oil. NOTE 2 It is not always possible to optimize test conditions simultaneously for inorganic and organic substances and optimum test conditions can also vary between different groups of organic substances. Test requirements for organic substances are generally more stringent than those for inorganic substances. The test conditions suitable for measuring the release of organic substances will generally also be applicable to inorganic substances. NOTE 3 Within the category of organic substances, a significant difference in behaviour exists between the more polar, relatively water-soluble compounds and apolar, hydrophobic organic substances (HOCs). In the latter case, mechanisms of release (e.g. particle-bound or dissolved organic carbon-bound) can be more crucial as well as sorption losses of soluble HOCs on different materials with which they come in contact (e.g. bottles, filters). The test and the results should be used for leaching of organic substances only with thorough consideration of the specific properties of the substances in question and the associated potential problems. NOTE 4 For ecotoxicological testing, eluates representing the release of both inorganic and organic substances are needed. In this document, ecotoxicological testing is also meant to include genotoxicological testing. This test method produces eluates, which can subsequently be characterized by physical, chemical and ecotoxicological methods in accordance with existing standard methods. The test is not suitable for substances that are volatile under ambient conditions. 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. This document does not address issues related to health and safety. It only determines the leaching properties as outlined in Clause 4.
