What is ISO 17225-3 about?
ISO 17225-3 determines the fuel quality classes and specifications of graded wood briquettes.
NOTE 1: ISO 17225-3 covers only wood briquettes produced from the following raw materials:
- Forest, plantation, and other virgin wood
- By-products and residues from the wood processing industry
- Chemically untreated used wood
NOTE 2: Thermally treated biomass briquettes (e.g. torrefied briquettes) are not included in ISO 17225- 3.
NOTE 3: Wood briquettes produced according to ISO 17225-3 can be used in stoves, fireplaces, cookers, room heaters, and multi fired sauna stoves.
Who is ISO 17225-3 for?
ISO 17225-3 on graded wood briquettes is beneficial for:
- Biofuel engineers
- Biodiesel operators
- Biochemical engineers
- Research labs
- Biodiesel producers
- Manufacturers of wood briquettes
Why should you use ISO 17225-3?
Wood briquettes for heat generation have been used in residential space heaters, boilers, and in distinct heating for several decades.
The objective of ISO 17225-3 is to provide the user with the unambiguous and clear classification principles for solid biofuels and to serve as a tool to enable efficient trading of biofuels and to enable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers. ISO 17225-3 facilitates authority permission procedures and reporting.
ISO 17225-3 supports the use of graded wood briquettes for residential, small commercial, and public building applications.
Overall, ISO 17225-3 is helpful as it assists with the fuel specifications and classes of graded wood briquettes, chemically treated wood by-products, and residues from the wood processing industry which can help you in your business.
What’s changed since the last update?
BS EN ISO 17225-3: 2021 supersedes BS EN ISO 17225‑3:2014, which is withdrawn. BS EN ISO 17225-3: 2021 cancels and replaces the first edition (ISO 172253:2014), which has been technically revised. The main changes compared to the previous edition are as follows:
