This part of ISO 17225 determines the fuel quality classes and specifications of graded wood chips. This part of ISO 17225 covers only wood chips 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

• 1.3.1 Chemically untreated used wood.

This standard covers only wood chips, which are produced with sharp tools, and does not cover hog fuel, which is produced with blunt tools.

This part of ISO 17225 determines the fuel quality classes and specifications of graded wood briquettes. This part of ISO 17225 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

— 1.3.1 Chemically untreated used wood

NOTE Thermally treated biomass briquettes (e.g. torrefied briquettes) are not included in the scope of this part of ISO 17225. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 – 300 °C.

This part of ISO 17225 determines the fuel quality classes and specifications for solid biofuels of raw and processed materials originating from

a) forestry and arboriculture;

b) agriculture and horticulture;

c) aquaculture.

Chemically treated material may not include halogenated organic compounds or heavy metals at levels higher than those in typical virgin material values (see Annex B) or higher than typical values of the country of origin.

NOTE Raw and processed material includes woody, herbaceous, fruit, aquatic biomass and biodegradable waste originating from above sectors.

This document specifies a classification system for solid recovered fuels (SRF), and a template containing a list of characteristics for the specification of their properties, enabling trade and use of SRF supporting the protection of the environment.

SRF are produced from non-hazardous waste.

NOTE 1 Untreated municipal solid waste as such cannot be considered SRF. Untreated municipal solid waste can however be feedstock to plants producing SRF.

NOTE 2 Chemically treated solid biofuels that do not contain halogenated organic compounds or heavy metals at levels higher than those in typical virgin material, can be defined as solid biofuels and thus be part of the standards series ISO 17225[1].

This international standard determines the terminology and definitions for solid biofuels. According to the scope of the ISO/TC 238 this standard only includes raw and processed material originating from

— forestry and arboriculture,

— agriculture and horticulture,

— aquaculture.

NOTE 1 Raw and processed material includes woody, herbaceous, fruit and aquatic biomass from the sectors mentioned above.

NOTE 2 Chemically treated material does not include halogenated organic compounds or heavy metals at levels higher than those in typical virgin material values or higher than typical values of the country of origin.

Materials originating from different recycling processes of end-of-life-products are not within the scope but relevant terms are included for information. Areas covered by ISO/TC 28/SC 7 "Liquid biofuels", ISO/TC 193 "Natural gas" and ISO/TC 300 "Solid recovered fuels" are excluded.

Other standards with a different scope than this International Standard may have different definitions than this standard.
