28、225-5:2014-09 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 understanding between seller and buyer as well as a tool for communication with
29、 equipment manufacturers. It will also facilitate authority permission procedures and reporting.This part of ISO 17225 supports the use of graded firewood for residential, small commercial and public building applications.The residential, small commercial and public building applications require hig
30、her 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 Appliances are often located in residential and populated districtsNOTE 1 Firewood produced according
31、 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 152505and EN 158216, and boilers systems tested according to EN 30357.NOTE 2 For individual
32、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 obtain and use ISO 17225-1 in conjunction with these standards.EN ISO 17225-5:2014 (E) 4 DIN
33、EN ISO 17225-5:2014-09 1 ScopeThis part of ISO 17225 determines the fuel quality classes and specifications of graded firewood. This part of ISO 17225 covers only firewood produced from the following raw materials (see ISO 17225-1, Table 1): 1.1.1 Whole trees without roots 1.1.3 Stem wood 1.1.4 Logg
34、ing residues (thick branches, tops etc.) 1.2.1 Chemically untreated wood residues2 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 applies. For undate

39、applications, which can utilize a much wider array of materials and have vastly different fuel requirements.4 Symbols and abbreviated termsThe symbols and abbreviated terms used in this part of ISO 17225 comply with the SI system of units as far as possible.d dry (dry basis)ar as receivedw-% weight-

The determination of the properties shall be carried out in accordance with the methods mentioned in the normative references.Ash, N, S, Cl a
43、nd minor elements are not required as firewood is produced from virgin material which has been grown in uncontaminated soil and therefore the likelihood of contamination is very low.Firewood specified according to classes A1 and A2 are suitable to be used in stoves and fireplaces and class B in log
44、wood boilers.How to state the dimensions of firewood is expressed in Figure 1.EN ISO 17225-5:2014 (E) 6 DIN EN ISO 17225-5:2014-09 KeyD maximum diameterL maximum lengthFigure 1 Dimensions of firewoodNOTE Firewood amounts are given in cubic metres or in kilograms. A cubic metre of stacked wood means
45、a stack of wood that occupies a space of one cubic metre. A cubic metre of loose wood is equal to a box one cubic metre in size into which the split logs are “thrown”. This is also referred to as an “unstacked cubic metre”. Naturally, the conversion rates between the volumes will be affected by the
46、size of the logs and how they are arranged. Comparison of different cubic meters is shown in informative Annex B.If the properties being specified are sufficiently known through information about the origin and handling (or preparation method combined with experience) then analysis may not be needed
47、.To ensure resources are used appropriately and the declaration is accurate, use the most appropriate measure below:1) using previous measured values or obtained by experience of same raw material;2) calculation of properties, e.g. by using typical values and considering generally accepted and docum
48、ented specific values;3) carrying out of analysis:a) with simplified methods if available;b) with reference methods.The responsibility of the producer or supplier to provide correct and accurate information is exactly the same whether laboratory analysis is performed or not. Typical values do not release the producer or supplier from providing accurate and reliable information.Chemical treatment before harvesting of biomass does not need to be stated
