Specification Requirements4.1 The properties of fabrics for woven neckties and scarfsshall conform to the specification requirements in Table 1.5. Significance and Use5.1 Upon mutual agreement between th
16、e 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 ultimate consumer of articles made from these fabrics mayfind acceptable fabrics that do no
17、t 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 to the specification shallspecify that: This fabric meets ASTM Specification D3785ex
18、cept 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 as a guide only. As noted in 5.2, ultimate consumerdemands dictate varying performanc
19、e 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 be performed on the fabric as it will reach theconsumer.6.2 Unless otherwise agreed u
20、pon, 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 in Practice D2905 to determine the numbe
21、r 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 a reliable estimate of variability of ind
22、ividualobservations on similar materials in the users laboratory underconditions of single-operator precision.7.

24、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, the CRT method shall prevail.7.2 Resistance to Yarn SlippageDetermine the resistanceto

There may be nooverall correlation between the results obtained with the tongue tearmachine and with the Elmendorf machine. Consequently, these two teartesters cannot be used interch
