This part of the European Standard EN 13965, Characterization of waste - Terminology, Part 1: Material related terms and definitions, concerns concepts which are related to different types of waste. It gives a compilation of selected and updated terms and definitions for use by for example producers, waste industry and legislators in the waste management field. It is harmonized with the current language used in management as well as in regulation. It includes, with references, national terms and definitions where such needs have been expressed. It does not include terms related to specialized activities. The scope of TC 292 excludes radio active wastes. Therefore such concepts are not included in this standard. Definitions in other standards with a scope different from the scope of this European Standard can be different from the definitions in this standard. NOTE In the context of European waste legislation an object can change from being a waste to being a non-waste during its life cycle. Typical examples are concepts making reference to e.g. a residue that may well be either a waste or a non-waste. The intention of this European Standard is not to distinguish between the two states but applies only to objects which have already been classified as waste on the basis of current regulations.
