This CEN/TR is to provide comprehensive information on two key aspects ofwaste testing, content and leaching. Some information is already available as informative annex in certain standard prepared by CEN/TC 292. But these annexes are not fully coherent and address only partly these two aspects, content and leaching. This CEN/TR provides, for instance for content testing, coherent and comprehensive information on the extraction methods and the interpretation of test results as well as guidance on the choice of such a method. This CEN/TR also provides, for instance for leaching tests, coherent and comprehensive information on the leaching methods, guidance on the selection of the adequate leaching test for the relevant scenario, and the interpretation of test results. In case of mass balance studies content is of relevance. Content is also of relevance for substances that are banned (zero level does not exist) or when leaching is not or not yet feasible for the substances of interest. Analysis of the content of substances in waste or waste derived products is of limited relevance from an environmental impact perspective, as generally only a very minor fraction of the total content of a substance in waste or waste derived product is leachable and thus can be transported from the waste or waste derived product to its surroundings through the water phase. For assessing impact of waste or a waste derived product the application of leaching tests is the preferred approach.
