General Attributes8.1 Accepta
17、ble defect levels and quality levels should beagreed upon between the buyer and the seller. The use ofrecycled fiber or other recycled material should not restrict theusefulness of the products covered under this guide, nor shouldit cause a product to not meet all specified requirements agreedupon b
18、etween the buyer and the seller.9. Bid Samples9.1 When requested, the bidder should submit a representa-tive product sample for examination purposes and data tosupport the claimed recycled content.An explanation should beincluded of the specific method(s) used to substantiate thatcontent, with indic
19、ation over what time period the measure-ments will be made.Aseparate sample should be submitted foreach class and type of packaging paper and paperboard productbeing bid on, along with supportive data and explanatoryinformation for each. Each sample should be clearly markedwith the bidders name and
20、address, bid number, and manu-facturers name or code number.10. Measurement Procedure10.1 Recycled fiber content should be calculated as the ratioof recycled fiber weight to total fiber weight in a given quantityof packaging paper or paperboard product and expressed as apercentage. The basic calcula
21、tion method is as follows (seeAppendix X1 for an example):RFC,%5RFU3 100VFU1 RFU(1)where:RFC= recycled fiber content, %,RFU= recycled fiber used, andVFU= virgin fiber used.10.1.1 The calculation of recycled content should be for afixed time period agreed upon between the buyer and the seller.10.1.1.
22、1 It is recommended that a monthly or quarterly timeperiod be used, as appropriate to the duration of the contractand production runs, for monitoring compliance of shippedproduct with its claimed level of recycled content during theterm of the buyer-seller agreement. An alternative time period,howev
23、er, may be agreed upon between the buyer and the seller.10.1.1.2 When multiple products of varying recycled con-tent are manufactured within a specified time period on a singlepaper machine, then the recycled content for a specific productshould be calculated based upon those time intervals withinth
24、at time period during which that specific product wasmanufactured.NOTE 1For example, if a calculation of monthly recycled content ina paperboard product is needed, and that product is manufactured for 10of the 30 days within that month on a specific paper machine, then onlythe amount and kinds of va
25、rious recycled and virgin materials used tomake that paper product on that paper machine during that 10-day periodshould be used to calculate the recycled content for that product using Eq1.10.1.1.3 When the same product of an agreed upon recycledcontent is manufactured within a specified time perio
26、d onseveral paper machines, then the recycled content for thatspecific product should be calculated based only upon thoseintervals within that time period, for each paper machine used,during which that specific product was manufactured. Forexample, if a calculation of monthly recycled content in apa
27、perboard product is needed, and that product is manufac-tured for 10 of the 30 days within that month on one papermachine and for 15 of the 30 days within that month on asecond paper machine, then only the amount and kinds ofvarious recycled and virgin materials used to make that paperproduct during
28、 those 10 and 15-day periods on the respectivepaper machines should be used to calculate the recycledcontent for that product by using Eq 1.10.2 The recycled content for a composite packaging paperor paperboard product composed of two or more components(for example, corrugating medium plus liner boa
29、rd) should beD5663 97 (2011)2calculated as the weighted mean recycled content of each of itscomponents, as follows (see Appendix X1 for an example):X1!P1! 1 X2!P2! 1 . 1 Xn!Pn!1005 recycled content, % (2)where:n = number of components in the composite paper pack-aging material,Xn= weight of recycled
30、 material in the nthcomponentcalculated using Eq 1, %, andPn= weight of the nthcomponent in a composite packag-ing material, %.10.2.1 An individual calculation of recycled content withina given time period (see 10.1.1 through 10.1.1.3) for eachcomponent should be made and recorded.10.3 The amount of
31、 recycled material in a given quantity ofpaper product (that is, used in Eq 1) should be determined bythe method in 10.3.1 or 10.3.2, as follows:10.3.1 When the paper manufacturer processes non-virginmaterial into recycled fiber, then the recycled content of aspecific paper product made from that re
32、cycled fiber should becalculated using the amount of recycled fiber obtained afterprocessing that recovered material; that is, from the actualyield of recycled fiber used in the furnish. The amount ofrecycled fiber obtained after processing may be calculated bymultiplying the weight of the recovered
33、 paper material pro-cessed by an appropriate yield factor for that material (relativeto recycled fiber) in that manufacturers specific process, asfollows:RFO5 NMP3 YF (3)where:RFO= recycled fiber obtained,NMP= nonvirgin material processed, andYF = yield factor.10.3.1.1 If several types of recovered
34、or recycled materialare used in the manufacture of a recycled content packagingpaper or paperboard product, then the recycled content of thatspecific paper product should be calculated by Method 1 or 2,as follows:(1) Method for Processing IndividuallyFor situationswhere one, or more, of the several
35、types of recovered materialsto be used are processed individually into their respectiverecycled fibers, the recycled content of the resultant paperproduct should be calculated using the amounts of each ofthose recycled fibers obtained after processing their respectiverecovered materials in both the
36、numerator and denominator ofEq 2, that is, from the actual weights of recycled fiber used inthe paper product furnish. For example, recovered old news-print and used office writing paper may be processed separatelyto acquire recycled groundwood and Kraft fiber, respectively.The yields of each of the
37、se fibers should be used to calculatethe recycled fiber weights to be used in Eq 1.(2) Method for Processing TogetherFor situations whereall of the several types of recovered materials used areprocessed together into recycled fibers, the recycled content ofthe resultant paper product should be calcu
38、lated as in 10.3.1from the amount of recycled fiber obtained after processing themixture of recovered materials; that is, from the actual yield ofrecycled fiber used in the paper product furnish. For example,recovered old newsprint and used office writing paper may beprocessed together to acquire a
39、mixture of recycled fiber. Theyield of mixed recycled fiber should be used in Eq 1.10.3.2 When the paper manufacturer uses recycled fiberprocessed by a recycled pulp supplier, that pulp supplier shouldsubstantiate the amount of recycled fiber in its recycled pulp.This may be calculated using the amo
40、unt of recycled fiberobtained after processing that recovered material; that is, byaccounting for the yield of recycled fiber from recovered papermaterial in its process (as in Eq 3). The recycled-pulp suppli-ers substantiated amount of recycled fiber content should beused to determine recycled cont
41、ent in a specified paper productmade from that fiber by the packaging paper or paperboardmanufacturer.10.4 The amount of virgin fiber used in a given quantity ofpaper product (that is, used in Eq 1), if present, should bedetermined by the method in 10.4.1 or 10.4.2, as follows:10.4.1 When the paper
42、manufacturer utilizes mill broke inthe manufacture of a paper product, then the virgin fibercontent of that mill broke is determined by calculating theamount of virgin fiber obtained after processing that millbroke; that is, from the actual yield of virgin fiber used in thepapermaking furnish. The a
43、mount of virgin fiber obtained afterprocessing may be calculated by multiplying the weight of thevirgin fiber portion of mill broke processed by an appropriateyield factor for that material (relative to virgin fiber) asfollows:VFO5 VFMBP3 YF (4)where:VFO= virgin fiber obtained,VFMBP= virgin fiber po
44、rtion of mill broke processed, andYF = yield factor.10.4.2 When the paper manufacturer uses virgin fiber pro-cessed by a pulp supplier, that pulp supplier should substantiatethe amount of virgin fiber in its pulp material by accounting forthe yield of virgin fiber from whatever material source is us
45、edin its process (as in Eq 4). The pulp suppliers substantiatedamount of virgin fiber content should be used in Eq 1.10.5 Yield factors (for Eq 3 or Eq 4) may be derived fromone or more of the following records:10.5.1 Periodic records of recovered paper material, virginfiber portion of mill broke, r
46、ecycled fiber or virgin fiber used,and levels of loss for each in preparation of fibers for inclusionin the paper manufacturing process,10.5.2 Periodic records of calibrated flowmeters and con-sistency regulators which monitor known fiber sources used inthe paper manufacturing process, or10.5.3 Peri
47、odic records of flow rates and fiber consistenciesof the various fiber sources used in the paper manufacturingprocess. Fiber consistencies may be determined by routineanalysis of samples taken from the fiber furnish stock tanks thatfeed into the paper machine.10.6 Other methods of calculating fiber
48、levels in the paperproducts are permissible, provided they can be documentedand standardized to the satisfaction of the buyer.D5663 97 (2011)311. Inspection of Recycled Content SubstantiationProcedure11.1 The buyer may request to review the procedures usedto substantiate the recycled content of a pa
49、ckaging paper orpaperboard product being bid upon or purchased.11.1.1 Inspection time(s) and frequency should be agreedupon between the buyer and the seller.12. Rejection and Rehearing12.1 If an inspection (see 11.1) or supplied substantiationdata with explanation fails to meet the bid award or otherpurchase specifications agreed upon between the buyer and theseller, the entire shipment of the class and type of product maybe subject to rejection, and the seller should be notified by thebuyer. Further procedures may be subject to prior agreementbetween the buyer and the se
