16、finitions found in a dictionary ofcommon terms are suitable for terms used in this specification.4. Specification Requirements4.1 The properties of fabrics for woven swimwear shallconform to the specification requirements in Table 1.5. Significance and Use5.1 Upon mutual agreement between the purcha

17、ser 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 recognized that for purposes of fashion or aestheticsthe ultimate consumer of articles made from these fabrics mayfind acceptable fabrics that do not conf

18、orm to all of therequirements in Table 1. Therefore, one or more of therequirements listed in Table 1 may be modified by mutualagreement between the purchaser and the supplier.5.2.1 In such cases, any references to the specification shallspecify that: “This fabric meets ASTM Specification D 3994,exc

19、ept for the following characteristic(s).”5.3 Where no prepurchase agreement has been reachedbetween the purchaser and the supplier, and in case ofcontroversy, the requirements listed in Table 1 are intended tobe used as a guide only. As noted in 5.2, ultimate consumerdemands dictate varying performa

20、nce parameters for anyparticular style of 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

21、 all material of asingle item received as a single shipment.6.2 Lot SampleAs a lot sample for acceptance testing,take at random the number of rolls as directed in an applicablespecification or other agreement between the purchaser and theseller, such as an agreement to use MIL-STD-105D.6.3 Laborator

22、y 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.6.4 Test Specimens Take the number of specimens di-rected in each of the applicable test methods. Perform the testson the fabric as it will reach th

23、e customer. Any “partiallyfinished” or “post-finish” fabrics should 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 D 2905 toTABLE 1 Specification RequirementsNOTE 1Class in

24、 a, b, and c is based on a numerical scale of 5 for negligible or no color change or color transfer to 1 for very severe color changeor color transfer.Characteristic Requirements SectionBreaking strength (load)A(CRT): 7.1Nonstretch fabrics 133 N (30 lbf), minStretch fabrics 89 N (20 lbf), min 40 % o

29、st results on laboratory 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 Methods7.1 Breaking Force De

30、termine the dry breaking force, inthe standard atmosphere for testing textiles, as directed in TestMethod D 5034, using a constant rate of traverse (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 l

31、ose strengthwhen wet, such as rayon, should be tested for wet breaking strength, also.NOTE 3If preferred, the use of a constant-rate-of-extension (CRE)testing machine is permitted. The crosshead speed should be as agreedbetween the purchaser and the supplier. There may be no overallcorrelation betwe

32、en the results obtained with the CRT and the CREmachines. Consequently these two breaking load testers cannot be usedinterchangeably. In case of controversy, the CRT machine shall prevail.7.2 Resistance to Yarn SlippageDetermine the resistanceto yarn slippage as directed in Test Method D 434.NOTE 4T

33、he precision of Test Method D 434 has not been established,and it may not be suitable for fabrics with low yarn counts in terms of thenumber of ends and picks per inch.7.3 Tear Strength Determine the tear strength in thenonstretch direction as directed in Test Method D 1424.NOTE 5If preferred, the u

34、se of Test Methods D 2261 or D 2262 ispermitted with existing requirements as given in this standard. There maybe no overall correlation between the results obtained by the tongue tearmethod and the Elmendorf method. Consequently these two tear testerscannot be used interchangeably. In case of contr

35、oversy, Test MethodD 1424 shall prevail.7.4 Dimensional Change:7.4.1 LaunderingDetermine the maximum dimensionalchange after five launderings as directed 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

36、 agreed between the purchaser and the supplier.7.5 Colorfastness:7.5.1 Burnt Gas Fumes Determine the colorfastness toburnt gas fumes on the original fabric and after one launderingas directed in AATCC Test Method 23.NOTE 6Washing conditions shall be the same as those used in 7.4.1.1.7.5.2 Laundering

41、 between them. Consequently, these machines cannotbe used interchangeably. In case of controversy, results obtained with theWater Cooled Xenon Arc machine listed in Option E shall prevail.7.5.10 Colorfastness to Chlorine BleachDetermine thecolorfastness to chlorine bleach as directed in AATCC TestMe
