For terms relating tochemical or colorfastness testing, refer to specific AATCCmethods.4. Specification Requirements4.1 The properties of fabric

16、s for woven swimwear shallconform to the specification requirements in Table 1.5. Significance and Use5.1 Upon mutual agreement between the purchaser and thesupplier, woven fabrics intended for this end use should meetall of the requirements listed in Table 1 of this specification.5.2 It is recogniz

17、ed 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 therequirements listed in Table 1 may be modified by mutualagreement between the purch

18、aser and the supplier.5.2.1 In such cases, any references to the specification shallspecify that: “This fabric meets ASTM Specification D3994,except for the following characteristic(s).”5.3 Where no prepurchase agreement has been reachedbetween the purchaser and the supplier, and in case ofcontrover

19、sy, the requirements listed in Table 1 are intended tobe used as a guide only. As noted in 5.2, ultimate consumerdemands dictate varying performance parameters for anyparticular style of fabric.5.4 The significance and use of particular properties and testmethods are discussed in the appropriate sec

20、tions of thespecified test methods.6. Sampling6.1 Acceptance Testing LotUnless there is prior agreementconsider as a lot for acceptance testing all material of a singleitem received as a single shipment.6.2 Lot SampleAs a lot sample for acceptance testing, takeat random the number of rolls as direct

21、ed in an applicablespecification or other agreement between the purchaser and theseller, such as an agreement to use MIL-STD-105D.6.3 Laboratory SampleFrom each roll or piece in the lotsample, cut two laboratory samples the full width of the fabricand at least 375 mm (15 in.) along the selvage.TABLE

Perform the testson the fabric as it will reach the customer. Any “partiallyfinished” or “post-finish” fabrics should

27、be processed inaccordance with the fabric manufacturers instructions.6.5 If the applicable test method does not specify thenumber of specimens, use the procedures in Practice D2905 todetermine the number of specimens per laboratory samplingunit. Use (1) a reliable estimate of the variability of indi

28、vidualobservations 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 laboratory samplingunits and the average for the laboratory sampling unit. Theaverage for a laboratory sampling unit is the av

29、erage thatwould be obtained by applying the test method to all of thepotential specimens from that laboratory sampling unit.7. Test Methods7.1 Breaking Force Determine the dry breaking force, inthe standard atmosphere for testing textiles, as directed in TestMethod D5034, using a constant rate of tr

30、averse (CRT) tensiletesting machine with the speed of the pulling clamp at 300 + 10mm (12 + 0.5 in.)/min.NOTE 2Fabrics that include fibers which are known to lose strengthwhen wet, such as rayon, should be tested for wet breaking strength, also.NOTE 3If preferred, the use of a constant-rate-of-exten

31、sion (CRE)testing machine is permitted. The crosshead speed should be as agreedbetween the purchaser and the supplier. There may be no overallcorrelation between the results obtained with the CRT and the CREmachines. Consequently these two breaking load testers cannot be usedinterchangeably. In case

32、 of controversy, the CRT machine shall prevail.7.2 Resistance to Yarn SlippageDetermine the resistanceto yarn slippage as directed in Test Method D434.NOTE 4The precision of Test Method D434 has not been established,and it may not be suitable for fabrics with low yarn counts in terms of thenumber of

33、 ends and picks per inch.7.3 Tear Strength Determine the tear strength in thenonstretch direction as directed in Test Method D1424.NOTE 5If preferred, the use of Test Methods D2261 or D2622 ispermitted with existing requirements as given in this standard. There maybe no overall correlation between t

34、he results obtained by the tongue tearmethod and the Elmendorf method. Consequently these two tear testerscannot be used interchangeably. In case of controversy, Test MethodD1424 shall prevail.7.4 Dimensional Change:7.4.1 LaunderingDetermine the maximum dimensionalchange after five launderings as di

35、rected in the applicableprocedure in AATCC 135 or as agreed between the purchaserand supplier.7.4.1.1 The wash conditions and drying procedure shall beas agreed between the purchaser and the supplier.7.5 Colorfastness:7.5.1 Burnt Gas Fumes Determine the colorfastness toburnt gas fumes on the origina

40、E 7There are distinct differences in spectral distribution betweenthe various types of machines listed in AATCC Test Method 16.3, with nooverall correlations between them. Consequently, these machines cannotbe used interchangeably. In case of controversy, results obtained with theWater Cooled Xenon
