Significance and Use5.1 Upon agreement between the purchaser and the supplier,fabrics intended for this end use should meet all of therequirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aesth

16、eticsthe 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 upon agree-ment between the purchaser and the supplier.5.2.1 In such cases,

17、any references to the specification shallspecify that: “This fabric meets ASTM Specification D 4112except 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

18、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 uses and significance of particular properties andmethods are discussed in the appropriate sections of thespecified methods.6. Sampling6.1 Lo

19、t 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 thesupplier, such as an agreement to use MIL-STD-105D.6.2 Laboratory SampleFrom each roll or piece in the lotsample, cut two labora

20、tory samples the full width of the fabricand at least 375 mm (15 in.) along the selvage.7. Test Methods (see Note 1)7.1 Breaking ForceDetermine the dry breaking force asdirected in Test Method D 5034, using a constant rate oftraverse (CRT) tensile testing machine with the speed of thepulling clamp a

21、t 300 6 10 mm (12 6 0.5 in.)/min.NOTE 2If preferred, the use of a constant-rate-of-extension (CRE)testing machine is permitted. The crosshead speed should be as agreedupon between the purchaser and the supplier. There may be no overallcorrelation between the results obtained with the CRT machine and

22、 theCRE machine. Consequently, these two breaking-load testers cannot beused interchangeably. In case of controversy, the CRT machine shallprevail.7.2 Resistance to Yarn SlippageDetermine the resistanceto yarn slippage as directed in Test Method D 434.NOTE 3The precision of Test Method D 434 is bein

23、g established, andit may not be suitable for fabrics with low-yarn counts in terms of endsand picks per inch (see 5.2).7.3 Yarn DistortionDetermine the yarn distortion as di-rected in Test Method D 1336.7.4 Tear StrengthDetermine the tear strength as directedin Test Method D 2262.NOTE 4If preferred,

24、 the use of Test Methods D 1424 and D 2261 ispermitted with existing requirements as given in this specification. Theremay be no overall correlation between the results obtained with thetongue-tear machines and the Elmendorf machine. Consequently, thesetear testers cannot be used interchangeably. In

25、 case of controversy, TestMethod D 2262 shall prevail.7.5 Colorfastness:7.5.1 GasDetermine the colorfastness to Burnt GasFumes (on the original fabric and after one laundering) asdirected in AATCC Method 23 after 1 cycle.7.5.2 LightDetermine the colorfastness to light as di-rected in AATCC Method 16

26、.NOTE 5There are distinct differences in spectral distribution betweenthe various types of machines listed in AATCC Test Method 16, with nooverall correlations between them. Consequently, these machines cannotbe used interchangeably. In case of controversy, results obtained with theWater-Cooled Xeno

27、n-Arc machine listed in Option E shall prevail.7.5.3 CrockingDetermine the colorfastness to crocking asdirected in AATCC Test Method 8 for solid shades and AATCCTest Method 116 for prints, or as agreed upon between thepurchaser and the supplier.7.5.4 OzoneDetermine the colorfastness to ozone as di-r

28、ected in AATCC Method 129.7.5.5 Colorfastness to Chlorine BleachDetermine the col-orfastness to chlorine bleach as directed in AATCCMethod 188.TABLE 1 Specification RequirementsNOTE 1Class for color change and color transfer is based on anumerical scale of 5 for negligible or no color change or colo
