1、Designation: E791 08 (Reapproved 2016)Standard Test Method forCalculating Refuse-Derived Fuel Analysis Data from As-Determined to Different Bases1This standard is issued under the fixed designation E791; the number immediately following the designation indicates the year oforiginal adoption or, in t

2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method gives equations to enable analyticaldata from the application of RDF

3、 analyses procedures to beexpressed on various different bases in common use. Suchbases are: as-received; dry; dry, ash-free; and others.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standard does not purport to a
