DIN EN ISO 17225-3:2014-09 IntroductionThe objective of the ISO 17225 series is to provide unambiguous and clear classification principles for solid biofuels; to serve as a tool to enable efficient trading of biofuels; to e
30、nable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers. It will also facilitate authority permission procedures and reporting.This part of ISO 17225 supports the use of graded wood briquettes for residential, small commercial and public bui
31、lding applications.The residential, small commercial and public building applications require higher quality fuel for the following reasons: Small-scale equipment does not usually have advanced controls and flue gas cleaning Appliances are not generally managed by professional heating engineers Appl
32、iances are often located in residential districtsNOTE 1 Wood briquettes produced according to this part of ISO 17225 may be used in stoves, fireplaces, cookers, roomheaters and multifired sauna stoves, which are tested according to European standards EN 132291, EN 128152, EN 128093, EN 132404, EN 15
33、2505and EN 158216, and boilers systems tested according to EN 30357.NOTE 2 For individual contracts ISO 17225-1 can be used.Although these product standards may be obtained separately, they require a general understanding of the standards based on and supporting ISO 17225-1. It is recommended to obt
34、ain and use ISO 17225-1 in conjunction with these standards.EN ISO 17225-3:2014 (E) 4 DIN EN ISO 17225-3:2014-09 1 ScopeThis 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 follow
35、ing 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 woodNOTE Thermally treated biomass briquettes (e.g. torrefied briquettes) are not included in the scope of this part o
36、f ISO 17225. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 C to 300 C.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited
37、 applies. For undated references, the latest edition of the referenced document (including any amendments) applies.NOTE ISO standards describing methods for analysis of fuel properties listed in the Bibliography, will become normative references when they are published.ISO 16559, Solid biofuels Term
