14、C700, West Conshohocken, PA 19428-2959. United States14. Specification Requirements4.1 The properties of fabrics for mens and boys knitteddress suits and sportswear jackets, slacks, and trousers shallconform to the specification requirements in Table 1.5. Significance and Use5.1 Knitted fabrics shou
15、ld meet all of the requirements inTable 1 to be suitable for use in the manufacture of dress suitsand sportswear jackets, slacks, and trousers for men and boys.5.2 It is recognized that for purposes of fashion or aestheticsthe ultimate consumer of articles made from these fabrics mayfind acceptable
16、some fabrics that do not conform to all of therequirements in Table 1. For example, the fabric could be dyedin shades that do not meet the requirement in Table 1 forcolorfastness to light, yet be acceptable to the ultimate con-sumer because the shade is fashionable. In such cases, one ormore of the
17、requirements may be modified by mutual agree-ment between the purchaser and the seller.5.2.1 If any of the requirements in Table 1 are modified bymutual agreement between the purchaser and the seller, anyreference to the specification shall specify that “this fabricmeets ASTM Specification D3782 exc
18、ept for the followingcharacteristic(s).”5.3 The uses and significance of particular properties arediscussed in the appropriate sections of the specific methods.6. Sampling6.1 Tests shall be performed on the fabric as it will reach theconsumer. Any “partially finished” or “post-finished” fabricsshoul
19、d first be processed in accordance with the fabric manu-facturers instructions.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 has been no prior agreement and the te
20、stmethod 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 average (that is, the average thatwou
21、ld be obtained by applying this method to the entire lot)when using a reliable estimate of variability of individualobservations on similar materials in the users laboratory underconditions of single-operator precision.7. Test Methods (See Note 1)7.1 Bursting StrengthDetermine the bursting strength,
22、 inthe standard atmosphere for testing textiles, as directed inMethod D231 using an approved type of constant-rate-of-traverse (CRT) machine equipped with a bursting attachmentor an approved type of diaphragm bursting tester as agreedupon between the purchaser and the seller.NOTE 2There is no overal
23、l 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, the CRT machineequipped with a bursting attachment method shall prevail
24、.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 by an interla
25、boratory 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 ManufacturingMarkspecimen(s) as directed in 4.3.1 of AATCC Method 135. Pressand finish

Measurethe specimen(s) and calculate the dimensional change asdirected in Sections 6 and 7 of AATCC Method 135.7.2.1.1 If no agreement ha
27、s 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 LaunderingDetermine the maximum dimensionalchange after five launderings as directed in the applicableprocedure in AATCC

29、irementsNOTE 1Class in a, b, c, and DP is based on a numerical scale of 5 fornegligible or no color change, color transfer, or wrinkle to 1 for verysevere color change, color transfer, or wrinkle.

Forexample, the fabric could contain a functional
34、 finish soluble in the solvent,or the fiber could be degraded by the solvent, which would be the casewith poly(vinyl chloride) fiber. “Dry-cleanable” goods are to be dry-cleaned only.NOTE 5Specimens prepared for 7.2.1 may be used for 7.2.2 and 7.2.3as desired. When this is done, subtract the pressin

The dimensional change topressing and finishing is determined on the fabric as it will reach the user.It is not additive to the dimensional change to laundering or dry cleanin
