• small-scale equipment does not usually have advanced controls and flue gas cleaning; • it is not generally managed by professional heating engineers; • they are often located in living and populated districts. NOTE Wood briquettes produced according to this European Standard can be used in stoves, fireplaces, cookers, roomheaters and multifired sauna stoves, which are tested according to EN 13229, EN 12815, EN 12809, EN 13240,
EN 15250 and EN 15821, and boilers systems tested according to EN 303-5 (< 500 kWth). SIST EN 14961-3:2011

densified biofuel made with or without additives in the form of cubiform or cylindrical units, produced by compressing pulverised biomass NOTE 1 The raw material for wood briquettes is woody biomass in accordance with Table 1 of EN 14961-1:2010. NOTE 2 Biofuel briquettes are usually manufactured in a piston press, with the total moisture content usually being less than 15 % of the mass on wet basis.
3.2 additive material which improves the quality of the fuel (e.g. combustion properties), reduces emissions or makes production more efficient 3.3 chemical treatment any treatment with chemicals other than air, water or heat (e.g. glue and paint)
NOTE Examples of chemical treatments are listed in informative Annex C of EN 14961-1:2010. 4 Symbols and abbreviations The symbols and abbreviations used in this European Standard comply with the SI system of units as far as possible. d
