Scope1.1 This test method covers the quantitative determinationof the components found in plumage. The test method isapplicable for plumage found in bulk

3、 form or in finishedconsumer products.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 address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the u

4、ser of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Test Method4.1 A representative sample of plumage is selected from theproduct being tested. The contents of th

7、e sample are identifiedand separated into component parts. Those component partsare measured and reported as a percentage of the whole.5. Significance and Use5.1 This test method may be used for acceptance testing ofcommercial shipments of bulk plumage.Acceptance tolerancesof content must be establi

8、shed between the purchaser and sellerof bulk shipments of plumage, which also must comply withstate and federal agency regulations, as appropriate.5.1.1 In case of a dispute arising from differences inreported test results when using Test Method D4524 foracceptance testing of commercial shipments, t

9、he purchaser andthe supplier should conduct comparative tests to determine ifthere is a statistical bias between their laboratories. Competentstatistical assistance is recommended for the investigation ofbias. As a minimum, the two parties should take a group of testspecimens that are as homogeneous

10、 as possible and that arefrom a lot of material of the type in question. The testspecimens should then be randomly assigned in equal numbersto each laboratory for testing. The average results from the twolaboratories should be compared using Students t-test forunpaired data and an acceptable probabi

11、lity level chosen by thetwo parties before the testing is begun. If a bias is found, eitherits cause must be found and corrected or the purchaser and thesupplier must agree to interpret test results in the light of theknown bias.5.2 This test method may also be applicable to the accep-tance of consu

12、mer products that use plumage as a fillingmaterial. Such consumer products include pillows, comforters,sleeping bags, garments, furniture, and mattresses.

16、Box C700, West Conshohocken, PA 19428-2959, United States.tolerances of content are established by distributors, importers,state or federal regulatory agencies. See 5.1.1.6. Apparatus6.1 Separating CabinetA box or cabinet for separatingand identifying the components of plumage. The box shouldhave th

17、e following approximate dimensions:Base450 by 300 mm (18 by 12 in.) wideFront150 mm (6 in.) highBack300 mm (12 in.) highThe top of the box will be glass to permit the separation tobe observed visually. The front of the box will have an opensection that will permit the operators hands to enter thecab

18、inet. Sufficient freedom of movement must be allowed sothat the components can be examined and segregated. Thecabinet should be equipped with a light to provide sufficientillumination of its interior. The interior cabinet color must be ofdark color to provide contrast with the plumage. See Fig. 1.6.

19、2 Weighing ContainersTen tared weighing bottles orbeakers to segregate the components and contain them duringweighing.6.3 Forceps, suitable for picking up components of theplumage.6.4 Balance, having a capability adequate for weighingspecimens and containers with a sensitivity of 0.0001 g.6.5 Mixing

20、 ContainersOne large box or container ap-proximately 500 by 500 by 500 mm that is used to hold thesample plumage to be analyzed. Another smaller mixingcontainer approximately 300 by 300 by 150 mm. The interiorof the mixing boxes shall be smooth to avoid plumageentrapment.7. Sampling7.1 Lot SampleAs

21、a lot sample for acceptance testing,select at random the number of bales, bags, or other shippingcontainers as directed in an applicable material specification orother agreement between the purchaser and the supplier. In theabsence of such an agreement, randomly select 30 % of theshipping containers

22、. From each of the shipping containersselected, remove a sample sufficient in mass to obtain a total lotsample of 300 g. Consider the shipping containers to be theprimary sampling units.NOTE 1An adequate specification or other agreement between thepurchaser and the supplier requires taking into acco

23、unt the variabilitybetween and within shipping containers to provide a sampling plan witha meaningful producers risk, consumers risk, acceptable quality level,and limiting quality level.7.2 Laboratory SampleAs a laboratory sample for accep-tance testing, randomly take portions of plumage from each l

24、otsample submitted weighing at least 10 g each from the upper,middle, and lower portion of the sample submitted, drawingeach sample from the middle of the submitted sample. Com-bine the three portions from the lot sample into a compositesample and use it as a test specimen for that sample submitted.

25、8. Procedure8.1 Specimen Reduction:8.1.1 Place the sample plumage in the larger mixing con-tainer and mix well by turning the plumage with the hands. Donot stir the sample with a stick.8.1.2 Draw the specimen to be analyzed from three sectionsof the mixing container (top, middle, and bottom) to weig

26、happroximately 4 g.8.2 Preliminary Separation:8.2.1 Place the test specimen in the separating cabinet andbegin the separation into plumage components.8.2.2 With the forceps, remove all feathers from the plum-age. Brush the feathers between the thumb and index fingers ofone hand to remove any down, f

27、iber, or residue caught therein.8.2.3 Separate the feathers into whole waterfowl feathers(Container A), damaged waterfowl feathers (Container C), andlandfowl feathers (Container B) and place each into anindividual tared weighing container.8.2.4 Place the down cluster, plumules, down fiber, andfeathe

28、r fiber that are all combined in the fourth tared weighingcontainer (Container E).8.2.5 Place the quill feathers in a fifth tared weighingcontainer (Container Q).8.2.6 Place the residue in a sixth weighing container (Con-tainer D).8.2.7 Weigh the contents of the six containers to the nearest0.0001 g

29、.8.3 Down and Fiber Separation:8.3.1 Place the contents of the container in 8.2.4 in thesmaller mixing container. Mix the contents by turning with thehands.FIG. 1 Down and Feather Separating CabinetD4524 86 (2012)28.3.2 Draw a sub-specimen to be analyzed that weighs aminimum of 0.200 g. Draw the plu

30、mage to be separated fromthree sections of the mixing container.8.3.3 Place the 0.200-g sub-specimen in the separatingcabinet. Separate the components as follows:8.3.3.1 With forceps remove a down cluster or plumule andshake five times from an up position to a down position and upagain. Slightly fli

31、ck the cluster as you go down and up again.8.3.3.2 Carefully remove the entwined feather fiber from thecluster or plumule with the forceps.8.3.3.3 Place the cluster or plumule into a weighing con-tainer (Container F). Place the feather fiber into a secondcontainer (Container H). Pick up the down fib

32、er with theforceps and place into a third weighing container (ContainerG).8.3.3.4 Do not remove entwined down fiber from theclusters. Only remove the down fiber that shakes loose.8.3.3.5 If landfowl feather, fiber is present, place it in afourth container (Container J).8.3.3.6 If residue is found in

33、 this portion of the separation,place it in a fifth container (Container K).8.3.3.7 Weigh the contents of the five containers to thenearest 0.0001 g.9. Calculations9.1 Preliminary Separation:9.1.1 Obtain total contents analyzed by adding together theweight of the waterfowl feathers, landfowl feather
