Terminology3.1 Definitions:3.1.1 plumage, nthe outgrowth of fowl, consisting offeathers and down (waterfowl) or feathers

6、only (nonwater-fowl).3.2 For the definitions of terms used in this standard, refer toTerminology D 123 and Terminology D 4523.4. Summary of Test Method4.1 A representative sample of plumage is selected from theproduct being tested. The contents of the sample are identifiedand separated into componen

7、t 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 established between the purchaser and sellerof bulk shipm

8、ents 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 D 4524 foracceptance testing of commercial shipments, the purchaser andthe supplier should conduct compa

9、rative 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 as possible and that arefrom a lot of material o

10、f 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 probability level chosen by thetwo parties before the te

11、sting 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 consumer products that use plumage as a fillingmateria

12、l. Such consumer products include pillows, comforters,sleeping bags, garments, furniture, and mattresses. Acceptancetolerances of content are established by distributors, importers,state or federal regulatory agencies. See 5.1.1.1This test method is under the jurisdiction of ASTM Committee D13 on Te

13、xtilesand is the direct responsibility of Subcommittee D 13.61 on Apparel.Current edition approved Sept. 1, 2005. Published December 2005. Originallyapproved in 1986.

16、ates.6. Apparatus6.1 Separating CabinetA box or cabinet for separatingand identifying the components of plumage. The box shouldhave the 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

17、 separation tobe observed visually. The front of the box will have an opensection that will permit the operators hands to enter thecabinet. Sufficient freedom of movement must be allowed sothat the components can be examined and segregated. Thecabinet should be equipped with a light to provide suffi

18、cientillumination of its interior. The interior cabinet color must be ofdark color to provide contrast with the plumage. See Fig. 1.6.2 Weighing ContainersTen tared weighing bottles orbeakers to segregate the components and contain them duringweighing.6.3 Forceps, suitable for picking up components

19、of theplumage.6.4 Balance, having a capability adequate for weighingspecimens and containers with a sensitivity of 0.0001 g.6.5 Mixing 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 appro

20、ximately 300 by 300 by 150 mm. The interiorof the mixing boxes shall be smooth to avoid plumageentrapment.7. Sampling7.1 Lot SampleAs a lot sample for acceptance testing,select at random the number of bales, bags, or other shippingcontainers as directed in an applicable material specification orothe

21、r agreement between the purchaser and the supplier. In theabsence of such an agreement, randomly select 30 % of theshipping containers. 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 thepri

22、mary sampling units.NOTE 1An adequate specification or other agreement between thepurchaser and the supplier requires taking into account the variabilitybetween and within shipping containers to provide a sampling plan witha meaningful producers risk, consumers risk, acceptable quality level,and lim

23、iting quality level.7.2 Laboratory SampleAs a laboratory sample for accep-tance testing, randomly take portions of plumage from each lotsample 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 s

24、ample. Com-bine the three portions from the lot sample into a compositesample and use it as a test specimen for that sample submitted.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 s

25、ample with a stick.8.1.2 Draw the specimen to be analyzed from three sectionsof the mixing container (top, middle, and bottom) to weighapproximately 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 f

26、orceps, remove all feathers from the plum-age. Brush the feathers between the thumb and index fingers ofone hand to remove any down, fiber, or residue caught therein.8.2.3 Separate the feathers into whole waterfowl feathers(Container A), damaged waterfowl feathers (Container C), andlandfowl feathers

27、 (Container B) and place each into anindividual tared weighing container.8.2.4 Place the down cluster, plumules, down fiber, andfeather 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.

28、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.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 Dow

Draw the plumage 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

30、.3.1 With forceps remove a down cluster or plumule andshake five times from an up position to a down position and upagain. Slightly flick 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

31、or plumule into a weighing con-tainer (Container F). Place the feather fiber into a secondcontainer (Container H). Pick up the down fiber 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

32、 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 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.
