1、Designation: E 870 82 (Reapproved 2006)Standard Test Methods forAnalysis of Wood Fuels1This standard is issued under the fixed designation E 870; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i

2、n parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the proximate and ultimateanalysis of wood fuels and the determination of the grosscaloric value of wood fuels sample

3、d and prepared by pre-scribed test methods and analyzed according to ASTM estab-lished procedures. Test methods as herein described may beused to establish the rank of fuels, to show the ratio ofcombustible to incombustible constituents, to provide the basisfor buying and selling, and to evaluate fo
