This International Standard determines the fuel quality classes and specifications of graded wood briquettes for non-industrial and industrial use. This International Standard covers only wood briquettes produced from the following raw materials (see ISO 17225-1 table 1):- 1.1 Forest, plantation and other virgin wood- 1.2 By-products and residues from wood processing industry- 1.3 Used woodNOTE 1 For the avoidance of doubt, demolition wood is not included in the scope of this International Standard. Demolition wood is "used wood arising from demolition of buildings or civil engineering installations".NOTE 2 Thermally treated briquettes (e.g. torrefied briquettes) are not included in the scope of this International Standard. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 - 300 C.
