Significance and Use5.1 Upon mutual agreement between the purchaser and theseller, fabrics intended for this end use should meet all of
16、therequirements 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 conform to all of therequirements in Table 1. Therefore, one or more of therequireme
17、nts listed in Table 1 may be modifed by mutualagreement between the purchaser 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
18、reachedbetween the purchaser and the seller, 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 performance parameters for anyparticular style of fabric.5.4 The significance and use of partic
19、ular properties and testmethods are discussed in the appropriate sections 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 presseddur
20、ing manufacturing should be processed in accordance withthe fabric manufacturers 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.6.2.1 If there h
21、as been no prior agreement and the testmethod does not specify the number of specimens, use theprocedures in Practice D2905 to determine the number ofspecimens, such that the user may expect at the 95 % prob-ability level that the test result is no more than 5 % of theaverage above or below the lot
22、average (that is, the average thatwould be obtained by applying this method to the entire lot)using a reliable estimate of variability of individual observa-tions on similar materials in the users laboratory underconditions of single-operator precision.TABLE 1 Specification RequirementsNOTE 1The cla

28、 Bursting StrengthDetermine the bursting strength asdirected 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 u
29、sed interchangeably. In case of controversy, Method D3787 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 according
30、ly not recommended for acceptance testingunless preceded 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 GarmentManufactu
31、ringWhere applicable mark the specimen(s) asdirected in 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 t
32、he dimensional change as directed inSections 6 and 7 of 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 Deter
33、mine the maximum dimen-sional change after five launderings as directed in the appli-cable procedure in AATCC Method 135 or as agreed uponbetween the purchaser and the seller.7.2.2.1 The wash conditions and drying procedure shall beas agreed upon between the purchaser and the seller (see Notes4 and
34、5).7.2.3 Institutional LaunderingThe wash conditions anddrying 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 )
35、.NOTE 4Launderable fabrics are expected to be drycleanable 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(viny
36、l) chloride fiber. “Drycleanable” goods are to be drycleanedonly.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 press
37、ing and finishing will have occurred in thefabric before 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
38、laundering or drycleaning, andD2= measurement after pressing and finishing.7.3 Fabric Smoothness AppearanceDetermine the fabricsmoothness appearance, as directed in AATCC Method 124,after laundering using the wash-and-wear cycle, or the normalcycle as agreed upon between the purchaser and the seller

40、 fabric smoothness durable press (DP) rating ofsuch fabrics, and the DP rating of drycleaned fabrics, shallhave decreased no more than 1/2 DP rating from that of thefabric before it is laundered or drycleaned.7.4 Flammability The flammability requirements shall beas agreed upon between the purchaser
41、 and the seller, exceptwhen regulated by applicable Government mandatory stan-dards.7.5 Colorfastness:7.5.1 Home Laundering Determine the colorfastness tolaundering of home laundered fabrics as directed in MethodAATCC 61.7.5.2 Institutional LaunderingDetermine the colorfast-ness to laundering of ins

Consequently, these machines cannotbe used interchangeably. In case of
45、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 15.7.5.8 Colorfastness to Sodium Hypochlorite BleachDetermine the colorfastness to sodium hypochlorite ble
