16、 mens and womenscareer apparel shall conform to the specification requirement inTable 1.5. Significance and Use5.1 Upon mutual agreement between the purchaser and theseller, fabrics intended for this end use should meet all of therequirements listed in Table 1 of this specification.5.2 It is recogni
17、zed 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 modifed by mutualagreement between the purch
18、aser and the seller.5.2.1 In such cases, any references to the specification shallspecify that: “This fabric meets ASTM Specification D3995except for the following characteristic(s).”5.3 Where no prepurchase agreement has been reachedbetween the purchaser and the seller, and in case ofcontroversy, t
19、he 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 sections
20、 of thespecified test methods.6. Sampling6.1 Tests shall be performed on the fabric as it will reach theconsumer.Any “partially finished” or “post-finished” fabrics orthose which will be pleated, creased, steamed, or pressedduring manufacturing should be processed in accordance withthe fabric manufa
21、cturers instructions before tests are made.6.2 Unless otherwise agreed upon, as when specified in anapplicable material specification, take the number of specimensdirected in each of the applicable test methods.TABLE 1 Specification RequirementsNOTE 1The grades of colorfastness and SA rating are bas

29、cted in Test Methods D3787 or D3786.NOTE 2There is no overall correlation between the results obtainedwith the CRT machine equipped with a bursting attachment and thediaphragm bursting tester. Consequently, these two bursting testers cannotbe used interchangeably. In case of controversy, Method D378
30、7 shallprevail.NOTE 3The precision of the ball burst method using the CRT machineequipped 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 testingunless preceded
31、 by an interlaboratory check test in the laboratory of thepurchaser and the laboratory of the seller using randomized replicatespecimens of the material to be evaluated.7.2 Dimensional Change:7.2.1 Pressing and Finishing During GarmentManufacturingWhere applicable mark the specimen(s) asdirected in
32、Section 4.3.1 of AATCC Method 135. Press andfinish specimen(s) as agreed by the purchaser and the sellerwith respect to time, cycles, temperature, steam, vacuum, andmechanical pressure of the press head. Measure the speci-men(s) and calculate the dimensional change as directed inSections 6 and 7 of
33、AATCC Method 135.7.2.1.1 If no agreement has been made between the pur-chaser and the seller, press the specimen(s) using a flat-bedsteam press according to the cycle in 10.1.3.1 through 10.1.3.5of Test Methods D2724.7.2.2 Home Laundering Determine the maximum dimen-sional change after five launderi

35、drying procedure shall be as agreed upon between the pur-chaser and the seller.7.2.4 Drycleaning Determine the maximum dimensionalchange after three drycleanings as directed in 10.1.3.1 through10.1.3.5 of Test Methods D2724 (see Notes 4 and 5 ).NOTE 4Launderable fabrics are expected to be drycleanab
36、le exceptwhere all or part of the fabric is not drycleanable and is so labeled. Forexample, the fabric could contain a functional finish soluble in the solvent,or the fiber could be degraded by the solvent, which would be the casewith poly(vinyl) chloride fiber. “Drycleanable” goods are to be drycle
37、anedonly.NOTE 5Specimens prepared for 7.2.1 may be used for 7.2.2, 7.2.3,and 7.2.4 as desired. When this is done, the dimensional change due tolaundering or drycleaning is calculated using Eq 1, due to laundering. Thedimensional change to pressing and finishing will have occurred in thefabric before
38、 it reaches the user. Therefore, it should not be included as apart of the dimensional change to laundering or drycleaning of the fabricas it will reach the consumer (see 6.1).% dimensional change 5 100 D22 D1!/D2(1)where:D1= measurement after laundering or drycleaning, andD2= measurement after pres

43、tain a combination of polyester and spandex, or their blends, may notshow the full staining propensity of such fabrics in consumer use. It is,therefore, recommended that the staining results obtained by these testsnot be used for acceptance testing of such fabrics.7.5.2 Institutional LaunderingDeter

46、 in 7.2.4 asdirected in AATCC Method 23.7.5.6 LightDetermine colorfastness to light as directed inAATCC Method 16.3.NOTE 7There are distinct differences in spectral distribution betweenthe various types of machines listed in AATCC Method 16.3, with nooverall correlations between them. Consequently,
47、these machines cannotbe used interchangeably. In case of controversy, results obtained with theWater Cooled Xenon Arc machine listed in Option 3 shall prevail.7.5.7 Perspiration Determine the colorfastness to perspi-ration as directed in AATCC Method 15 (see Note 6).D3995 1437.5.8 Colorfastness to S
