The tests need not be performed when available thermodynamic information (e.g. heat of formation, heat of decomposition) and/or absence of certain reactive groups (2) in the structural formula establishes beyond reasonable doubt that the substance is incapable of rapid decomposition with evolution of gases or release of heat (i.e. the material does not present any risk of explosion).

'energy recovery` shall mean the use of combustible packaging waste as a means to generate energy through direct incineration with or without other waste but with recovery of the heat;

Where cogeneration installations are equipped to generate separate electricity or heat production, such production should not be specified as cogeneration for issuing a guarantee of origin and for statistical purposes.

"recycling" means the reprocessing in a production process of the waste materials for the original purpose or for other purposes, but excluding energy recovery which means the use of combustible waste as a means of generating energy through direct incineration with or without other waste but with recovery of the heat;

'household appliance' means any machine, portion of a machine or installation manufactured principally for use in dwellings, including cellars, garages and other outbuildings, in particular household appliances for upkeep, cleaning purposes, preparation and storage of foodstuffs, production and distribution of heat and cold, air conditioning, and other appliances used for non-professional purposes;
