本文件规定了获取材料短期和长期浸出行为及特性信息的试验。 该文件旨在测量土壤和类土壤材料中无机和有机物质的pH依赖性释放，并为后续生态毒理学测试生成洗脱液。有关生态毒理学测试，请参见ISO 15799和ISO 17616。本文件中定义的平衡条件是通过添加预定量的酸或碱来达到所需的最终pH值。 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:无机物和有机物的试验条件并非总是可以同时优化，不同有机物组的最佳试验条件也可能不同。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试验条件通常也适用于无机物质。 注3:在有机物质类别中，极性较高、相对水溶性的化合物与非极性、疏水性的有机物质（HOC）之间的行为存在显著差异。在后一种情况下，释放机制（e。 g、 颗粒结合或溶解有机碳结合）以及可溶性HOC在与之接触的不同材料（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特性和相关潜在问题的情况下，才能将试验和结果用于有机物质的浸出。 注4:对于生态毒理学测试，需要代表无机物和有机物释放的洗脱液。在本文件中，生态毒理学测试包括基因毒理学测试。 试验方法产生洗脱液，随后可根据现有标准方法，通过物理、化学和生态毒理学方法对其进行表征。 本试验不适用于环境条件下易挥发的物质。 为了进行生态毒理学试验，相关pH范围（见8.2）通常为pH 5至pH 9。 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。本文件不涉及与健康和安全相关的问题。它仅确定第5条中概述的浸出性质。

This document specifies a test to obtain information on the short- and long-term leaching behaviour and characteristic properties of materials. The document has been developed to measure the pH-dependent 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 and ISO 17616. The equilibrium condition, as defined in this document, is established by the addition of predetermined amounts of acid or base to reach desired final pH values. 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 meant to include genotoxicological testing. The 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. For the purposes of ecotoxicological tests, the relevant pH range (see 8.2) will usually be pH 5 to pH 9. 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 outlined in Clause 5.
