标准范围

ISO 18772:2008提供了关于适当使用土壤和土壤材料浸出试验的指导，以便在影响评估框架内确定浸出行为，或出于合规和比较目的，包括以下信息:浸出试验的选择，取决于要解决的问题的性质和不同试验的具体特点；测试结果的解释；测试的局限性。在这方面，重要的是要记住，浸出测试的目的不是模拟真实的现场条件，而是旨在解决固相和液相之间的接触，用于ISO 18772:2008中描述的不同目的。ISO 18772:2008仅涉及天然、受污染和农业土壤和土壤材料。ISO 18772:2008未涵盖与废物浸出有关的问题。它也不包括ISO 17402涵盖的污染物对活生物体的生物利用度。

ISO 18772:2008 provides guidance on the appropriate use of leaching tests on soil and soil materials, in order to determine the leaching behaviour in the framework of impact assessment, or for compliance and comparison purposes, including information on the following:

• the choice of leaching tests, depending on the nature of the problem to be solved and the specific features of the different tests;
• the interpretation of the test results;
• the limitations of the tests.

In this respect, it is important to keep in mind that leaching tests do not aim to simulate real field conditions, but are designed to address the contact between a solid and a liquid phase for different purposes that are described in ISO 18772:2008.ISO 18772:2008 only concerns natural, contaminated and agricultural soils and soil materials. Questions relating to the leaching of wastes are not covered by ISO 18772:2008. It also does not cover the subject of bioavailability of contaminants to living organisms, which is covered by ISO 17402.
