14、textile terms see Terminol-ogy D123.4. Specification Requirements4.1 The properties of woven comforter fabrics shall con-form to the specification requirements in Table 1.5. Significance and Use5.1 Upon mutual agreement between the purchaser andseller, fabrics intended for this end use should meet a
15、ll therequirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aestheticsthe ultimate consumer of articles made from these fabrics mayfind acceptable fabrics that do not conform to all of therequirements in Table 1. Therefore, one or more of therequir
16、ements listed in Table 1 may be modified by mutualagreement between the purchaser and seller.5.2.1 If any of the requirements in Table 1 are modified bymutual agreement between purchaser and seller, any referenceto the specification shall state that: “This fabric meets ASTMSpecification D4769, excep
17、t for the following characteris-tic(s).”5.3 Where no prepurchase agreement has been reachedbetween the purchaser and seller, and in case of controversy,the requirements listed in Table 1 are intended to be used as aguide only. As stated in 5.2, ultimate consumer demandsdictate varying performance pa
18、rameters for any particular styleof fabric.5.4 The significance and use of particular properties and testmethods are discussed in the appropriate sections of thespecified test methods.6. Sampling6.1 Acceptance Testing LotUnless there is prior agree-ment, consider as a lot for acceptance testing all
19、material of asingle item received as a single shipment.6.2 Lot Samples and Laboratory Samples For acceptancetesting, take lot samples and laboratory samples as directed ineach of the applicable test methods.6.3 Test SpecimensTake the number of specimens di-rected in each of the applicable test metho
20、ds. Perform the testson the fabric as it will reach the customer. Any “partiallyfinished” or “post-finish” fabrics should be processed inaccordance with the fabric manufacturers instructions.6.4 If the applicable test method does not specify thenumber of specimens, use the procedures in Practice D29
21、05 todetermine the number of specimens per laboratory samplingunit. Use (1) a reliable estimate of the variability of individualobservations on similar materials in the users laboratory, (2)a95 % probability level, and ( 3) an allowable difference of 5 %of the average between the test results on lab
22、oratory samplingunits and the average for the laboratory sampling unit. Theaverage for a laboratory sampling unit is the average thatwould be obtained by applying the test method to all of thepotential specimens from that laboratory sampling unit.7. Test Methods (See Note 1)7.1 Breaking StrengthDete
23、rmine the breaking strength asdirected in Test Method D5034, using a constant-rate-of-extension (CRE) tensile-testing machine.NOTE 2If preferred, the use of a constant-rate-of-traverse (CRT)tensile testing machine is permitted. There may be no overall correlationbetween the results obtained with the
24、 CRT machine and the CRE machine.Consequently, these two breaking force testers cannot be used inter-changeably. In case of controversy, the CRE method (Test Method D5034)shall prevail.7.2 Bursting StrengthDetermine the bursting strength ofknit fabrics in the standard atmosphere for testing textiles
25、, asdirected in Test Method D3786, or Test Method D6797 asagreed between the purchaser and seller.NOTE 3There is no overall correlation between the results obtainedwith the CRE machine equipped with a bursting attachment and thediaphragm bursting tester. Consequently, these two bursting testers cann
26、otbe used interchangeably. In case of controversy, the motor-driven dia-phragm tester method (Test Method D3786) shall prevail.NOTE 4The precision of the bursting strength testers has not beenestablished. The methods are accordingly not recommended for accep-tance testing unless preceded by an inter
27、laboratory check in the labora-tories of the purchaser and seller, using randomized replicate specimens ofthe material to be evaluated.7.3 Tear StrengthDetermine the tear strength of wovenfabrics as directed in Test Method D1424.NOTE 5If preferred, the use of Test Methods D2261 is permitted, withexi
28、sting requirements as given in this specification. There may be nooverall correlation between the results obtained with the tongue tearmethod (Test Method D2261), and the Elmendorf machine (D1424).Consequently, these three testers cannot be used interchangeably. In caseof controversy, Test Method D1
29、424 shall prevail.7.4 Dimensional Change:7.4.1 LaunderingDetermine the maximum dimensionalchange after five launderings as directed in AATCCMethod 135, using the wash conditions and drying proceduresspecified by the seller.TABLE 1 Specification RequirementsNOTE 1Class in A, B, and C, and D.P. rating

37、ines listed in AATCC Test Method 16 with nooverall correlation between them. Consequently, these machines cannot beused interchangeably.
