1、Designation: D5663 97 (Reapproved 2011)D5663 15 An American National StandardStandard 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 adopti

2、on or, in the 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 guide provides an approach for both the calculation and the substanti

3、ation of recycled content of finished packagingpaper and paperboard products.Amass balance approach is recommended for use by manufacturers since no physical or chemicaltest method is currently available to determine absolute recycled content of a finished paper product. Calculations are based on ti

4、meweighted average flows which are based on furnish component flow rates and consistency. Recommended approaches to thecalculations include by batch or by time weighted average for a specific grade or similar grades. It is not recommended that averagerecycle content be allocated by mathematical appo

5、rtionment rather than by actual fiber content. That is, if 50% recycled fiber isused over time that is the time weighted average. One cannot use this same data to report 50% of the production is 100% recycled.1.1.1 Percentage calculations are based on lb/ton or kg/tonne with the time frame constrain

6、ed by machine and grade (see10.1.1.1 and 10.1.1.2).1.1.2 Pulping and recycling yields are not used in these calculations. The calculations of recycled fiber content in the finishedproduct is solely a function of type of fibers in the furnish flows, the volume of flow and the time period considered.1

7、.2 This guide covers (1) recycled content of packaging paper and paperboard products that contain any amount or kind ofrecycled fiber; and (2) methods to calculate and substantiate the level(s) of recycled fiber content claimed by an agreement betweenthe buyer and the seller.1.2.1 This guide may be

8、used with or without modification to calculate or substantiate the recycled content of packaging paperand paperboard products when recovered nonfibrous materials (for example, filler) are a part of the recycled fiber furnish. Limitedguidance is provided for appropriate modifications to this guide fo

9、r the determination of amount of recycled nonfibrous materialsin paper products.1.3 This guide does not recommend either an amount or a kind of recycled fiber or material to use since (1) the amount andkind of recycled content in a packaging paper or paperboard product should be agreed upon between

10、the buyer and the seller, and(2) the calculation and substantiation procedures recommended may be used for any amount or kind of recycled material agreedupon between the buyer and the seller.1.4 The mass balance calculation method recommended by this guide may or may not comply with applicable feder

11、al, state,or local laws for recycled content statements intended to be received by consumers. Limited guidance on content statements is inAppendix X1.1.5 The following safety hazards caveat pertains only to the test method portion, Section 10, of this guide:This standard doesnot purport to address a

18、cedures and data used by the seller to monitor compliancewith the agreed-upon recycled content of product(s) under contract.6. Composition6.1 Recycled content of packaging paper and paperboard products supplied in accordance with this guide should be agreed uponbetween the buyer and the seller (see

19、5.1).6.2 The average recycled content for a packaging paper or paperboard product shipped from the seller to the buyer within aspecified time period (see 10.1.1 through 10.1.1.3) should be at least equal to the contracted recycled content or be within a degreeof variation (see 6.3) of that content.6

20、.3 The buyer and the seller may agree to a degree of variation in the recycled content in shipped product from the seller tothe buyer when multiple shipments will take place over the contract period; however, any degree of variation for recycled contentgreater than 10 % is not recommended. In additi

21、on, recycled content of a shipment of product that exceeds the degree of variationagreed upon by the buyer and the seller should be reported by the seller to the buyer in an agreed-upon manner.6.4 Recycled content of packaging products composed of two or more components should be reported as the wei

22、ghted meanrecycled content of the multiple components (see 10.2).6.5 All measures of recycled content should be on a dry weight (0 % moisture) basis.an air dry or conditioned weight basis asspecified by the buyer (see 5.1.2).7. Physical Attributes7.1 The average value of physical characteristics, wo

23、rkmanship, dimensions, and appearance for any product should meet therequirements agreed upon by the buyer and the seller with reference to appropriate ASTM or standards of other organizations.8. General Attributes8.1 Acceptable defect levels and quality levels should be agreed upon between the buye

24、r and the seller. The use of recycled fiberor other recycled material should not restrict the usefulness of the products covered under this guide, nor should it cause a productto not meet all specified requirements agreed upon between the buyer and the seller.9. Bid Samples9.1 When requested, the bi

25、dder should submit a representative product sample for examination purposes and data to support theclaimed recycled content. An explanation should be included of the specific method(s) used to substantiate that content, withindication over what time period the measurements will be made. A separate s

26、ample should be submitted for each class and type3 Available from the Technical Association of the Pulp and Paper Industry, P.O. Box 105113, Atlanta, GA 30348.D5663 152of packaging paper and paperboard product being bid on, along with supportive data and explanatory information for each. Eachsample

27、should be clearly marked with the bidders name and address, bid number, and manufacturers name or code number.10. Measurement Procedure10.1 Recycled fiber content should be calculated as the ratio of recycled fiber weight to total fiber weight in a given quantityof packaging paper or paperboard prod

28、uct and expressed as a percentage. The basic calculation method is as follows (see AppendixX1 for an example): example, see 10.4.1 Eq 3 and Eq 4 when mill paper machine broke is used):RFC,%5RFU3100VFU1RFU(1)RFC,%5RFU 3 100!VFU 1RFU! (1)where:RFC = recycled fiber content, %,RFU = recycled fiber used,

29、 andRFU = weight recycled fiber used (for example, kg fiber component per t of final product), andVFU = weight virgin fiber used.10.1.1 The calculation of recycled content should be for a fixed time period agreed upon between the buyer and the seller.10.1.1.1 It is recommended that a monthly or quar

30、terly time period be used, as appropriate to the duration of the contract andproduction runs, for monitoring compliance of shipped product with its claimed level of recycled content during the term of thebuyer-seller agreement. An alternative time period, however, may be agreed upon between the buye

31、r and the seller.10.1.1.2 When multiple products of varying recycled content are manufactured within a specified time period on a single papermachine, then the recycled content for a specific product should be calculated based upon those time intervals within that timeperiod during which that specif

32、ic product was manufactured.NOTE 1For example, if a calculation of monthly recycled content in a paperboard product is needed, and that product is manufactured for 10 of the30 days within that month on a specific paper machine, then only the amount and kinds of various recycled and virgin materials

33、used to make that paperproduct on that paper machine during that 10-day period should be used to calculate the recycled content for that product using Eq 1.10.1.1.3 When the same product of an agreed upon recycled content is manufactured within a specified time period on severalpaper machines, then

34、the recycled content for that specific product should be calculated based only upon those intervals within thattime period, for each paper machine used, during which that specific product was manufactured. For example, if a calculation ofmonthly recycled content in a paperboard product is needed, an

35、d that product is manufactured for 10 of the 30 days within thatmonth on one paper machine and for 15 of the 30 days within that month on a second paper machine, then only the amount andkinds of various recycled and virgin materials used to make that paper product during those 10 and 15-day periods

36、on the respectivepaper machines should be used to calculate the recycled content for that product by using Eq 1.10.2 The recycled content for a composite packaging paper or paperboard product composed of two or more components (forexample, corrugating medium plus liner board) should be calculated as

37、 the weighted mean recycled content of each of itscomponents, as follows (see Appendix Appendix X1X1.4 for an example):X1!P1!1X2!P2!11Xn!Pn!100 5recycled content,% (2)X1!P1!1X2!P2!11Xn!Pn!#31005recycled content,% (2)where:n = number of components in the composite paper packaging material,Xn = weight

38、 of recycled material in the nth component calculated using Eq 1, %, andXn = weight percent of recycled material in the nth component calculated using Eq 1, andPn = weight percent of the nth component in a composite packaging material, %.10.2.1 An individual calculation of recycled content within a

39、given time period (see 10.1.1 through 10.1.1.3) for eachcomponent should be made and recorded.10.3 The amount of recycled material in a given quantity of paper product (that is, used in Eq 1) should be determined by themethod in 10.3.1 or 10.3.2, as follows:10.3.1 When the paper manufacturer process

40、es non-virgin material into recycled fiber, then the recycled content of a specificpaper product made from that recycled fiber should be calculated using the amount of recycled fiber obtained after processing thatrecovered material; that is, from the actual yield of recycled fiber used in the furnis

41、h. The amount of recycled fiber obtained afterprocessing may be calculated by multiplying the weight of the recovered paper material processed by an appropriate yield factorfor that material (relative to recycled fiber) in that manufacturers specific process, as follows: material.RFO5NMP3YF (3)where

42、:D5663 153RFO = recycled fiber obtained,NMP = nonvirgin material processed, andYF = yield factor.10.3.1.1 If several types of recovered or recycled material are used in the manufacture of a recycled content packaging paperor paperboard product, then the recycled content of that specific paper produc

43、t should be calculated by Method 1 or 2, as follows:(1) Method for Processing IndividuallyIndividuallyForFor situations where one, or more, of the several types of recoveredmaterials to be used are processed individually into their respective recycled fibers, the recycled content of the resultant pa

44、perproduct should be calculated using the amounts of each of those recycled fibers obtained after processing their respective recoveredmaterials in both the numerator and denominator of Eq 2, that is, from the actual weights of recycled fiber used in the paper productfurnish. For example, recovered

45、old newsprint and used office writing paper may be processed separately to acquire recycledgroundwood and Kraft fiber, respectively. The yields of each of these fibers should be used to calculate the recycled fiber weightsto be used in Eq 1.(2) Method for Processing TogetherTogetherForFor situations

46、 where all of the several types of recovered materials usedare processed together into recycled fibers, the recycled content of the resultant paper product should be calculated as in 10.3.1fromthe amount of recycled fiber obtained after processing the mixture of recovered materials; that is, from th

47、e actual yield of recycledfiber used in the paper product furnish. For example, recovered old newsprint and used office writing paper may be processedtogether to acquire a mixture of recycled fiber. The yield of mixed recycled fiber should be used in Eq 1.10.3.2 When the paper manufacturer uses recy

48、cled fiber processed by a recycled pulp supplier, that pulp supplier shouldsubstantiate the amount of recycled fiber in its recycled pulp. This may be calculated using the amount of recycled fiber obtainedafter processing that recovered material; that is, by accounting for the yield of recycled fibe

49、r from recovered paper material in itsprocess (as in material. Eq 3). The recycled-pulp suppliers substantiated amount of recycled fiber content should be used todetermine recycled content in a specified paper product made from that fiber by the packaging paper or paperboard manufacturer.10.4 The amount of virgin fiber used in a given quantity of paper product (that is, used in Eq 1), if present, should be determinedby the method in 10.4.1 or 10.4.2, as follows:10.4.1 When the The paper manufacturer utilizes mill may utilize mill paper machine broke in the m
