18、t is recognized that, for purposes of fashion 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 agreemen
19、tbetween the purchaser and the supplier.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
20、 case of controversy,the requirements listed in Table 1 are intended to be used as aguide only.As noted in 4.2, ultimate consumer demands dictatevarying performance parameters for a particular product.4.4 The uses and significance of particular properties andtest methods are discussed in the appropr
