Specification Requirements4.1 The properties of fabrics for woven neckties and scarfsshall conform to the specificatio
16、n requirements in Table 1.5. Significance and Use5.1 Upon mutual agreement between the purchaser and theseller, woven fabrics intended for this end use should meet allof the requirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aestheticsthe ultima
17、te 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 modified by mutualagreement between the purchaser and the seller.5.2.1 In such cases, any references
18、 to the specification shallspecify that: This fabric meets ASTM Specification D3785except for the following characteristic(s).5.3 Where no prepurchase agreement has been reachedbetween the purchaser and the seller, and in case ofcontroversy, the requirements listed in Table 1 are intended tobe used
19、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 of thespecified test methods.6. Sampling6.1 Tests shall
20、be performed on the fabric as it will reach theconsumer.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 speci
21、fy the number of specimens, use theprocedure 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 applyi
22、ng 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 Breaking Strength (Load)Determine the dry breakingstrength, in the standa
23、rd atmosphere for testing textiles, asdirected in the grab test procedure of Test Methods D1682,using a constant-rate-of traverse (CRT) tensile testing machinewith the speed of the pulling jaw at 12 6 0.5 in. (305 6 13mm)/min.NOTE 2If preferred, the use of a constant-rate-of-extension (CRE)tensile t
24、esting machine is permitted. The crosshead speed should be asagreed upon between the purchaser and the seller. There may be no overallcorrelation between the results obtained with the CRT machine. Conse-quently these two breaking load testers cannot be used interchangeably. Incase of controversy, th
25、e CRT method shall prevail.7.2 Resistance to Yarn SlippageDetermine the resistanceto yarn slippage as directed in Test Method D434.NOTE 3The precision of Test Method D434 is being established andit may not be suitable for fabrics with low yarn counts (see 5.2) in termsof ends and picks per inch.7.3
26、Tongue Tear StrengthDetermine the tongue tearstrength as directed in Test Method D2262.NOTE 4If preferred, use of Test Method D1424 is permitted withexisting requirements as given in this specification. There may be nooverall correlation between the results obtained with the tongue tearmachine and w
27、ith the Elmendorf machine. Consequently, these two teartesters cannot be used interchangeably. In case of controversy, TestMethod D2262 shall prevail.7.4 Yarn Distortion Determine the yarn distortion asdirected in Test Method D1336.7.5 Dimensional Change:TABLE 1 Specification RequirementsNOTE 1Grade

36、ystandard AATCC Test Methods, on fabrics dyed to dark shades thatcontain 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 ac
