DIN EN ISO 17225-4:2014-09 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 enable good und
31、erstanding between seller and buyer as well as a tool for communication with equipment manufacturers. It also facilitates authority permission procedures and reporting.This part of ISO 17225 supports the use of graded wood chips for residential, small commercial and public building applications.The
32、residential, small commercial and public building applications require higher quality fuel for the following reasons: Small-scale equipment usually does not have advanced controls and flue gas cleaning. Appliances are not generally managed by professional heating engineers. Appliances are often loca
33、ted in residential and populated districts.NOTE 1 Wood chips produced according to this part of ISO 17225 may be used in boilers tested according to EN 30351.NOTE 2 For individual contracts, ISO 17225-1 can be used.Although these product standards may be obtained separately, they require a general u
34、nderstanding of the standards based on and supporting ISO 17225-1. It is recommended to obtain and use ISO 17225-1 in conjunction with these standards.EN ISO 17225-4:2014 (E) 4 DIN EN ISO 17225-4:2014-09 1 ScopeThis part of ISO 17225 determines the fuel quality classes and specifications of graded w
35、ood 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 wood2 Normative referencesThe followi
36、ng 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 applies.
