Specification Requirements4.1 The properties of knitted fabrics for womens and girls sport
18、swear shall conform to the specification requirements in Table1.5. Significance and Use5.1 Upon mutual agreement between the purchaser and the seller, fabrics intended for this end use should meet all of therequirements listed in Table 1 of this performance specification.5.2 It is recognized that fo
19、r purposes of fashion or aesthetics the ultimate consumer of articles made from these fabrics may findacceptable fabrics that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed inTable 1 may be modified by mutual agreement between the purchaser an
20、d the seller.5.2.1 In such cases, any references to the specification shall specify that: “This fabric meetsASTM Specification D4156 exceptfor the following characteristic(s).”5.3 Where no prepurchase agreement has been reached between the purchaser and the seller, and in case of controversy, thereq
21、uirements listed in Table 1 are intended to be used as a guide only.As noted in 5.2, ultimate consumer demands dictate varyingperformance parameters for any particular style of fabric.5.4 The uses and significance of particular properties and test methods are discussed in the appropriate sections of
22、 the specifiedtest methods.6. Sampling6.1 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 the supplier, such as an agreement to use MIL-STD-105D.6.2 Laboratory SampleFrom each
23、roll or piece in the lot sample, cut two laboratory samples the full width of the fabric andat least 375 mm (15 in.) along the selvage,7. Test Methods (See Note 1)7.1 Bursting StrengthDetermine the bursting strength as directed in Test Methods D3786 or D3787 as agreed between thepurchaser and the se
24、ller.NOTE 2Care should be taken to subtract the tare diaphragm pressure from the gross pressure to obtain actual bursting strength of fabric when usingthe diaphragm bursting tester. Calibrate the equipment according to the manufacturers instruction before use. Since there is no overall correlation b
25、etweenthe results obtained with the CRT machine equipped with a bursting attachment and the diaphragm bursting tester, these two bursting testers cannot beused interchangeably. In case of controversy, Test Method D3786 shall prevail.NOTE 3The precision of the ball burst method using the CRT machine
26、equipped with a bursting attachment and the precision of the diaphragmbursting tester method are being established by Subcommittee D13.59. The methods are accordingly not recommended for acceptance testing unless5 Available from Standardization Documents Order Desk, Bldg. 4 Section D, 700 Robbins Av

If the difference betw
40、een the percent stretch of thelaundered fabric and the percent shrinkage due to laundering does not exceed 3 % shrinkage then the fabric meets the specificationrequirement in Table 1.7.2.3 DrycleaningDetermine the maximum dimensional change after three drycleanings or as agreed between the purchaser
41、and the seller in accordance with Sections 10.1.1 through 10.1.5 of Test Methods D2724 (Notes 5 and 6 ).NOTE 5Launderable fabrics are expected to be drycleanable except where all or part of the fabric is not drycleanable and is so labeled. For example,the fabric could contain a functional finish sol
42、uble in the solvent, or the fiber could be degraded by the solvent, which would be the case with poly(vinylchloride) fiber. “Drycleanable” goods are to be drycleaned only.NOTE 6Specimens prepared for 7.2.1 may be used for 7.2.2 and 7.2.3 as desired. When this is done the dimensional change due to la
43、undering ordrycleaning is calculated using Eq 1.The dimensional change to pressing and finishing is determined on the fabric as it will reach the user.

47、 in consumer use. It is, therefore,recommended that the staining results obtained by these tests not be used for acceptance testing of such fabrics.7.3.3 DrycleaningDetermine colorfastness to drycleaning as directed in AATCC Method 132 (see Note 6).7.3.4 CrockingDetermine colorfastness to dry and we
