ISO/TS 17225-8:2016 determines the fuel quality classes and specifications of graded densified solid biofuels produced from thermally treated biomass for non-industrial and industrial use. This document covers pellets and briquettes produced from the following raw materials (see ISO 17225‑1:2014, Table 1):
- 1.1 Forest, plantation and other virgin wood;
- 1.2 By-products and residues from wood processing industry;
- 1.3.1 Chemically untreated used wood;
- 2. Herbaceous biomass;
- 3. Fruit biomass;
- 4. Aquatic biomass.
Subcategories of the above stated raw materials are included.
ISO/TS 17225-8:2016 does not consider products, which are marketed as charcoal or as charcoal products. For these products, ISO 17225‑1:2014, Table 14 shall apply.
NOTE 1 For thermally treated powder, ISO 17225‑1:2014, Table 15 or Table 16 may be used for specification.
NOTE 2 Health, safety and environmental issues for solid biofuels are important and need special attention; however, they are outside the scope of this document.
