14、ion 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 should meet all of the requirements inTable 1 to be suitable for use in
15、 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 some fabrics that do not conform to all of therequirements in Table
16、 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 requirements may be modified by mutual agree-ment between the purch
17、aser 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 except for the followingcharacteristic(s).”5.3 The uses and significan
18、ce 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” fabricsshould first be processed in accordance with the fabric manu-facturers i
19、nstructions.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 testmethod does not specify the number of specimens, use theprocedure
20、s 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 thatwould be obtained by applying this method to the entire lot)when using
21、 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, inthe standard atmosphere for testing textiles, as directed inMeth
22、od 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 overall correlation between the results obtainedwith the CRT machine equi
23、pped 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.NOTE 3The precision of the ball burst method using the CRT machine
24、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 testingunless preceded by an interlaboratory check test in the laboratory of thepurchaser and the labor

Forexample, the fabric could contain a functional finish soluble in the solvent,or the fiber co
34、uld 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 pressing and finishingdimensional change from the tot
35、al dimensional change to obtain thatportion due to laundering or dry cleaning. 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 cleaningof the fabric as it will reach the consumer (

38、ation 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.7.3.3 Dry CleaningDetermine colorfastness to dry

41、em. Consequently, these machines cannotbe used interchangeably. In case of controversy, results obtained with thewater-cooled xenon-arc machine listed in Option 3 shall prevail.7.3.7 Colorfastness to Sodium Hypochlorite BleachDetermine colorfastness to sodium hypochlorite bleach asdirected in AATCC
