Significance and Use4.1 Upon mutual agreement between the purchaser and thesupplier, seamless knit garments intended for this end useshould meet all of the requirements listed in Table 1 of thisspecification.4.2 It is recognized that, for purposes of f
17、ashion or aesthet-ics, the ultimate consumer of articles made from these fabricsmay find acceptable products that do not conform to all of therequirements listed in Table 1. Therefore, one or more of therequirements in Table 1 may be modified by mutual agreementbetween the purchaser and the supplier
18、.4.2.1 In such cases, any references to the specificationsshould specify that: “This product meets ASTM specificationsXXXX except for the following characteristic(s).”4.3 Where no pre-purchase agreement has been reachedbetween the purchaser and supplier, and in case of controversy,the requirements l

Sampling5.1 Acceptance Testing LotUnless agreed otherwise, con-sider as a lot for acceptance testing all material of a single itemas a single shipment.5.2 Lot Samples and Laboratory SamplesFor acceptancetesting, take lot samples and laboratory samples as directed byeach of the applicable test
21、 methods.5.3 SpecimensTake the number of specimens directed ineach of the applicable test methods. Perform the tests on theproduct as it reaches the consumer. Any “partially finished” or“post-finish” fabrics should be processed in accordance withthe fabric manufacturers instructions.5.3.1 If the app
