标准摘要
[中文适用范围]： 本文件规定了一项测试，提供有关在下文指定的实验条件下，特别是在液固比为 10 l/kg 干物质下的土壤和土壤材料浸出的信息。 该文件的开发目的是测量土壤和类土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出液。 对于生态毒理学测试，请参见 ISO 15799[6] 和 ISO 17616[7]。 注 1：挥发性有机物质包括混合物中的低分子量物质，例如矿物油。 注 2：并不总是能够同时优化无机和有机物质的测试条件，并且不同有机物质组之间的最佳测试条件也可能有所不同。 有机物质的测试要求通常比无机物质更严格。 适用于测量有机物质释放的测试条件通常也适用于无机物质。 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（HOC）之间存在显着的行为差异。 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HOC在与其接触的不同材料（例如瓶子、过滤器）上的吸附损失可能更为重要。 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，测试和结果才能用于有机物质的浸出。 注 4 对于生态毒理学测试，需要代表无机和有机物质释放的洗脱液。 在本文件中，生态毒理学测试还包括遗传毒理学测试。 该测试方法产生洗出液，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的物质。 本程序不适用于干物质含量比低于 33% 的物料。 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，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。 [外文原描述]： 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.
