This European Standard describes the necessary steps to be performed before carrying out
ecotoxicity tests on wastes. The purpose of this European Standard is to provide guidance on the
taking of the sample, transport, storage of wastes and to define preparation, for the determination of
ecotoxicological properties of wastes under the conditions specified in this European Standard by
biological testing either as raw wastes or water extracts from wastes. Sample preparation for other
applications (e.g. assessment of waste effects on aquatic and terrestrial organisms in a disposal
scenario) is not considered. Specifying a test battery to characterize ecotoxicological properties of wastes is not in the scope of this European Standard. This European Standard is applicable to solid and liquid wastes.
