This European Standard determines the fuel quality classes and specifications for solid biofuels. According to the mandate given for the standardisation work, the scope of the CEN/TC 335 only includes solid biofuels originating from the following sources: a) products from agriculture and forestry; b) vegetable waste from agriculture and forestry; c) vegetable waste from the food processing industry; d) wood waste, with the exception of wood waste which can contain halogenated organic compounds or heavy metals as a result of treatment with wood preservatives or coating, and which includes in particular such wood waste originated from construction and demolition waste; e) fibrous vegetable waste from virgin pulp production and from production of paper from pulp, if it is co-incinerated at the place of production and heat generated is recovered; f) cork waste. NOTE 1 For the avoidance of doubt, demolition wood is not included in the scope of this European Standard. Demolition wood is ""used wood arising from demolition of buildings or civil engineering installations"" (CEN/TS 14588). NOTE 2 Aquatic biomass is not included in the scope of this European Standard.
