14、 Conshohocken, PA 19428-2959. United States14. Significance and Use4.1 Upon mutual agreement between the purchaser and the supplier, woven high stretch fabrics used in apparel should meet allof the requirements listed in Table 1 of this specification.4.2 It is recognized that, for purposes of fashio
15、n or aesthetics, the ultimate consumer of articles made from these fabrics mayfind acceptable products that do not conform to all of the requirements listed in Table 1. Therefore, one or more of the requirementsin Table 1 may be modified by mutual agreement between the purchaser and the supplier.4.2
16、.1 In such cases, any references to the specifications should specify that: “This product meets ASTM specifications XXXXexcept for the following characteristic(s).”4.3 Where no pre-purchase agreement has been reached between the purchaser and supplier, and in case of controversy, therequirements lis
17、ted in Table 1 are intended to be used as a guide only.As noted in 4.2, ultimate consumer demands dictate varyingperformance parameters for a particular product.4.4 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specifiedtest meth
