Significance and Use4.1 Upon mutual agreement between the purchaser and thesupplier, woven high stretch fabrics used in apparel shouldmeet all of the requirements listed in Table 1 of this specifi-cation.4.2 It is recognized that, for purposes of fashion
10、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.4.2.1
11、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 listed i
