1、Designation:D566315(Reapproved 2020)Standard Guide forValidating Recycled Content in Packaging Paper andPaperboard1This standard is issued under the fixed designation D5663;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of
2、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 guide provides an approach for both the calculationand the substantiation of recycled content of finished packag-ing p
3、aper and paperboard products.Amass balance approach isrecommended for use by manufacturers since no physical orchemical test method is currently available to determineabsolute recycled content of a finished paper product.Calcu-lations are based on time weighted average flows which arebased on furnis
4、h component flow rates and consistency.Rec-ommended approaches to the calculations include by batch orby time weighted average for a specific grade or similar grades.It is not recommended that average recycle content be allocatedby mathematical apportionment rather than by actual fibercontent.That i

6、lping and recycling yields are not used in thesecalculations.The calculations of recycled fiber content in thefinished product is solely a function of type of fibers in thefurnish flows,the volume of flow and the time period consid-ered.1.2 This guide covers(1)recycled content of packagingpaper and
